'Both Sides' Of The Climate Change Debate? How Bad We Think It Is, And How Bad It Really Is

The Guardian

It’s time to stop being mealy-mouthed about this. No more silent passes to climate science deniers

Over the past couple of weeks things have been happening on the climate change front but, unfortunately, little is changing in parliament, where the government’s direct action policy has continued to be an utter failure and a Queensland LNP MP suggested in his first speech in the House of Representatives that schools should teach both sides of the climate change debate in school – to prevent them being “brainwashed with extreme left or right ideologies”.
Last week came news that BHP was going to spend US$400m over five years on a “climate investment program to develop technologies to reduce emissions from its own operations as well as those generated from the use of its resources”.
Its CEO, Andrew Mackenzie, stated in a speech in London, “Society’s combustion of fossil fuels and industrial processes like steelmaking and agriculture have released greenhouse gases at rates much faster than at any other time in the geological past.”
To ram the message home he concluded: “The evidence is abundant: global warming is indisputable. The planet will survive. Many species may not.”
Just ponder that: many species will not survive.
Thus it was not particularly surprising really to hear this week that the NSW HSC was going to include climate change in geography classes. The surprising element was that it doesn’t already.
The government is utterly failing to achieve even its own pathetically low emissions reduction targets
Neither was it surprising to see conservatives across the media come out against it, arguing that if they are to teach climate change then they need to teach “both sides”. The IPA’s “director of the foundations of western civilisation program” Bella d’Abrera (yeah, I know) suggested on Sky News that “they’re going to hear hopefully that climate change is not necessary manmade”.
Or in other words, students should hear that conspiracy theories are real.
This is the type of guff that you expect to hear from the libertarian romper room that Sky News is now. It’s a station that gives a voice to the likes of Andrew Bolt, who this week devoted a column to calling 16-year-old climate-change activist Greta Thunberg “deeply disturbed” and mocking her autism diagnosis.
She responded by flicking him away with ease – which to be honest was not wholly difficult given I’ve had cases of tinea that have contributed more to our national intelligence than has Bolt’s entire media career. But she did it with class.
In parliament you would hope for better than the dredge we get on Sky News. But no.
On Wednesday, newly elected Queensland MP Terry Young gave his first speech, in which he stated “we want our children and grandchildren to hear the theories of evolution and creation, different religions, climate change advocates and climate change sceptics. I can say what we don’t want for us and our kids is to be brainwashed with extreme left or right ideologies.”
“Theories of creation”? Religion is a theory now?

He continued arguing, “When I hear a school principal stand up at school assembly and say ‘if this government doesn’t do anything about climate change, the world will end in 2030’ I get angry, because we should not indoctrinate our kids with fear mongering.”
Now, firstly, I’d like to know where that happened because I can find no record of it. It sort of happened in the TV show Big Little Lies, so maybe that was it.
But here’s the thing, he should get angry if he hears that – not because it is brainwashing but because his government is not doing anything about climate change.
The world is not going to end in 2030, but if we have not taken massive steps by then, our ability to prevent massive global degradation and harm due to climate change will be beyond us.
This is not extremist, it is science – science that was announced in October by the UN IPCC. Its co-chair said at the time: “This is the largest clarion bell from the science community and I hope it mobilises people and dents the mood of complacency.”
But no, it didn’t.
Young went on to suggest personal responsibility was more important and the fact his family own a hybrid car and have solar panels was a sign of how conservatives go about things the right way.
It is much the same line we have heard by so many conservatives – a variant of if we all plant a tree and recycle then that’s all we can do.
It won’t be anywhere near enough, and it might seem like “common sense” to Young but it is not. Just how lacking the LNP’s climate change policy is in anything approaching substance was revealed this week when its latest auction under the “emissions reduction fund” bought cuts equivalent to only 0.01% of Australia’s annual greenhouse gas pollution.
The government is utterly failing to achieve even its own pathetically low emissions reduction targets.
And time is running out fast.
This week in the Monthly, ANU climate scientist Dr Joëlle Gergis wrote that, while in 2013 scientists had estimated that a doubling of CO2 levels from pre-industrial levels (which we’re on track to do by 2060) would lead to a temperature increase of between 1.5C to 4.5C, now as scientists continue to get more data, their models suggest the temperature increase is more likely to be between 2.8C and 5.8C.
That’s scary because all efforts at the moment are assuming if we reduce emissions by 45% by 2030 we can limit warming to 1.5C. That might now be rather too optimistic.
Add into the mix came further news this week that glaciers appear to be melting 10 to 100 times faster than expected.
It’s time to stop being mealy-mouthed about this and to give silent passes to those peddling climate-change denialism either explicitly or implicitly by demanding we listen to both sides.
But OK, here’s both sides of the debate – for well over 40 years scientists have been researching and testing evidence that climate change is occurring due to CO2 emissions. They have found conclusive evidence that there is a link and that on the current path by 2100 global temperatures will likely reach 3C above pre-industrial levels.
The other side is that they have kept researching and testing the data, and sorry, they were wrong – it’s even worse than they thought.

How Climate Change Could Trigger The Next Global Financial Crisis

The Atlantic

The Federal Reserve should act aggressively to reduce that risk, a leading economic historian argues.

A few years ago, Mark Carney, a former Goldman Sachs director who now leads the Bank of England, sounded a warning. Global warming, he said, could send the world economy spiraling into another 2008-like crisis. He called for central banks to act aggressively and immediately to reduce the risk of climate-related catastrophe, taking the warming planet as seriously as they would a cooling economy.
Adam Tooze, a history professor at Columbia University, knows quite a bit about central banks—and the Great Recession. Last year he published Crashed, an award-winning account of the 2008 collapse and its aftermath. In that book, he argues that the U.S. Federal Reserve was the pivotal American institution in stopping a second Great Depression. Its actions were “historically unprecedented, spectacular in scale,” he writes, and widely understood by experts to be the “decisive innovation of the crisis.”
Now, in an article this month in Foreign Policy, Tooze asserts that the Fed needs to battle climate change in the same way. “If the world is to cope with climate change, policymakers will need to pull every lever at their disposal,” he writes. “Faced with this threat, to indulge in the idea that central banks, as key agencies of the state, can limit themselves to worrying about financial stability … is its own form of denial.”
Jerome Powell, the Fed chairman, would not call himself a climate-change denier. Indeed, he is probably the most powerful person in the American government who affirms climate science. Yet he has taken a subdued approach to mitigating climate change. In April, in a letter to Senator Brian Schatz, Powell wrote that “addressing climate change is a responsibility that Congress has entrusted to other agencies.”
The Federal Reserve, he added, is using its tools to “prepare financial institutions for severe weather.” In England, by contrast, Carney has convened 33 central banks to investigate how to “green the financial system.According to Axios, every powerful central bank is working with him—except for Banco do Brasil and the Fed. I talked with Tooze last week about whether climate change could really cause another global crash, how to think about climate policy in history, and what the Fed could do to decarbonize the economy. Our conversation has been edited for length and clarity.



Robinson Meyer: In your Foreign Policy piece, you draw an analogy between the financial crisis of 2008 and what’s happening now with climate change. You describe a crisis in a near-term future, one where climate change has taken hold but where much of the economy is still tied up in oil. I will say: I’m a little skeptical. I’m not sure you could get the kind of sudden financial stop through climate change that you got in 2007 and 2008. What’s the right way to think about that analogy?
Adam Tooze: That skepticism is perfectly warranted. I’d say that in some sense, I’m here writing with my historian’s hat on, and all I’m really observing is that Mark Carney, the governor of the Bank of England, in 2015, in a speech which has subsequently received massive coverage—and he is a man, after all, absolutely of the global financial establishment—coined the idea of a climate Minsky moment. [Editor’s note: A Minsky moment is when an asset’s price suddenly collapses after a long period of growth.]
So the point, to me, is not so much the realism of that prospect, of the fact that we could have some kind of subprimelike scenario. For me, the significant thing is that the argument is actually going on inside the establishment, in the network of financial regulators and central-bank thinkers.
Are we likely to see a financial Minsky moment? I think that is a reasonable question mark. We would need [fossil-fuel assets] to be on the balance sheet of actors who were under huge pressure in a fire-sale situation and who couldn’t deal with a sudden revaluation. We would need an entire network of causation to be there, which is what produced the unique crisis of 2007 to 2008.

Meyer: What would cause that kind of sudden revaluation? Would there need to be a policy shock, such as the United States suddenly imposing a climate policy?
Tooze: That would be one way in which this could be sudden. So imagine that we stay on our current path, and we’re headed toward 3 or 4 degrees’ [Celsius] temperature change. And then imagine some of the nonlinearities kick in, which the climate scientists tell us about, and we face a Fukushima-style event.
What happens next? You then get nervous democratic politicians—and not necessarily those who are known for their populism, but just nervous democratic politicians—suddenly deciding that we have to stop doing one or another part of our carbon-based economy.
It has to stop, and it has to stop immediately. And then you get big shocks. Then you get sudden revaluations.
That, I think, is the sort of scenario that the Bank of England people are working with. In other words, the success of the delaying tactics of the carbon lobby create a situation in which we’re then faced with the possibility of a sudden regulatory shock, something that really inflicts major losses.

Meyer: You quote this astonishing statistic: “One-third of equity and fixed income assets issued in global financial markets can be classified as belonging to the natural resource and extraction sectors, as well as carbon-intensive power utilities, chemicals, construction, and industrial goods firms.” Who is in that group? Are those the oil majors such as Exxon, or does that encompass every construction firm?
Tooze: It isn’t just the oil and gas majors, because they wouldn’t get you to 30 percent. Exxon isn’t big enough to get you to that kind of percentage. It’s Exxon, and [the major automakers] Daimler and BMW, and the entire carbon-exposed complex.
In Germany right now, there’s a very serious conversation about whether BMW and Daimler are too big to fail. Americans don’t have that sense of a manufacturing industry anymore—except, of course, we did end up bailing out GM in 2008.
But Germany is far, far more exposed. A huge slice of their economy is basically all about internal combustion engines, and so that number includes all of those stocks, for sure.

Meyer: And just to get back to the financial-crisis point, if there were some kind of immediate crunch, and all those stocks tanked …
Tooze: Yes. If we saw a huge shock to, say, European equity [exchange-traded funds], which were heavily in German automotive, that’s the sort of trigger that we might be looking at.

Meyer: In your view, what do you see as the goal of climate policy? Is it only to reduce carbon emissions? Do you see any benefits to the economic transition that we scientifically have to make, beyond mitigating climate change?
Tooze: I mean, that’s been the green-modernization agenda of climate politics, certainly in Europe, since the 1980s, right? This is not simply a zero-sum game; this is a structural transformation that has many very attractive properties.
There’s loads of excellent jobs that could be created in this kind of transition. There’s no reason why, even by conventional GDP-type metrics, it need even be associated with the kind of feel-bad factor of slow GDP growth.
Then [you could] also link it to a revival of social democracy for the United States. From a progressive political point of view, that’s obviously extremely attractive.
Whether that will, in fact, ease the formation of majorities in Congress is another question. Because, after all, it does somehow have to get through the Senate, you know.

Meyer: Yes, well, welcome to the life of a climate-change reporter. You get to talk about lots of ideas and policies, but then it’s all about what will survive the Senate.
Tooze: Exactly. I mean, ever since the 1990s that’s been the logjam on any serious American commitment. So …

Meyer: I think part of what I’m asking is: When you look at a third of securities tied up in the carbon economy and the evidence for decoupling GDP growth from carbon emissions maybe not being as strong as we’d like, do you think the change that needs to happen is realistic?
Tooze: Realistic? No. I mean, depends what you mean by realism. The scale of the challenge requires a boldness of action for which there is no precedent. That’s the only good purpose that the war analogies serve, in my mind.
I think in many ways the war-emergency analogy is terribly unhelpful because [climate change] is not that kind of challenge at all really, but at least that gives you some measure of the scale and urgency of what’s necessary.

Meyer: In your piece, you write: “Those in the United States who call for a Green New Deal or a Green Marshall Plan are, if anything, understating the scale of what is needed.” Do you think climate action needs to be larger than, say, the U.S. mobilization for World War II?
Tooze: Well, less large in absolute terms. Because even the U.S. was spending almost 40 percent of GDP on World War II. And if you’re the Soviet Union, you’re spending 55 to 60 percent in 1940. We don’t need to do anything like that.
It needs to be much bigger than the New Deal, which in fiscal-policy terms was really quite trivial. Crucially, what makes it totally unlike the war is that there’s no happy end. There’s no moment where you win and then everything goes back to the way it was before, but just better.
That’s a misunderstanding.
This isn’t crash dieting; this is a permanent change in lifestyle, and we need to love that and we need to live it and we need to own it and we need to reconcile ourselves to the fact that this is for us and for all subsequent generations of humans.
And furthermore—and much more fundamentally than any of those things—this isn’t really about America. I mean, America can be an obstacle and get in the way, but none of the really hard choices needs to be made by America, and all the really hard choices need to be made by people like China and India and Pakistan and Bangladesh and Indonesia.
Our choices are all trivially easy, because for all the assets that we’re going to lose, we need to create $5 trillion worth of new ones.

Meyer: What’s the closest analogy to what needs to happen? Is there a single historical analogy that we could think of—of a broad transition with no happy victory parades at the end?
Tooze: I don’t think I’m uncomfortable with saying that this is unprecedented, so I’m not sure that looking for analogies is all that helpful, to be honest. I don’t write lessons-from-history-type pieces, because I really buy the hockey stick.
[Editor’s note: The “hockey stick” graph shows that economic growth over the past 300 years has been unprecedented compared with human history before it.]
In other words, we have never had to fundamentally rethink the energy basis of our way of life. I mean, we never have.

Meyer: Industrialization has only happened once.
Tooze: Exactly. And furthermore, it has turned out to be exponential—a hockey-stick-style process. So no, it’s not obvious to me that [analogies are] a terribly helpful way of thinking about it. It strikes me, perhaps, as an indication of the poverty of our democratic imagination right now that we go backwards so much.
One of the striking things about the American left is its nostalgia. There’s always some moment that you can handily pick up, a lesson you can learn from the New Deal. Or if not the New Deal, then the Progressive era. Or if not from the Progressive era, then the Homestead Strike. Like there’s some heritage of struggle that you want to draw on.
And that backwards move is—even among the smartest, smartest people on the American left—is a compulsion, almost. It seems to me, in some sense, a mirror image of the strange practice of originalist interpretation of the Constitution. The sheer fact of the continuity of the American political argument, back to the founding, sucks people into this line of thinking.
You don’t have that very much in Germany. There isn’t anyone in Germany saying, “Which bit of mid-20th-century history is this most like?,” mercifully. The one analogy that has popped up in Germany is reunification, which I actually think is quite a good one, because that’s still an ongoing problem.
So in the American case, it would be civil rights and Reconstruction, which isn’t a particularly optimistic comparison to draw. It’s an ongoing problem, it’s a deep historic problem, it only happened once, we still haven’t fixed it, and we’re not at peace.

Meyer: There’s a kind of shallow view of climate change: that it is something we need to avert or stop. And that’s somewhat true. But there’s also a deeper view: that climate change is the situation within which all other politics will happen for the next several generations, at least. That like Reconstruction or the civil-rights movement, it needs to be something that people take on like a moral commitment, in the same way they take on genocide prevention as a moral commitment.
Tooze: I’m not sure quite why you go to moral commitment here. I can see the attraction of that. But I would take a more functionalist line. Like, morals aside, mass incarceration, the destruction of the lives of millions of African American men—it is clearly a moral issue. But that isn’t, to me, the thing which should give it urgency.
The crisis that African American men suffer in the United States is extraordinarily acute and oppresses them every single day of their lives, from cradle to grave.
Anyway, this is the point where I think this analogy becomes problematic. I do like your point that this is a forever problem—at least for all conceivable futures—like working through that problem of racism and the legacies of slavery is a forever problem in the United States.

Meyer: And there’s a degree to which it also increases the functional load on everything else.
Tooze: Yes. Because problems that we thought we’d fixed, like the Green Revolution and the feeding of the world population, for instance—totally not obvious that those fixes cope with the next 20 years of what’s ahead of us.
The food problem that was such an oppressive issue globally in the 1970s may resurge in an absolutely dramatic way.

Meyer: Given all that, if Jerome Powell decided that he wanted to intervene on the side of climate action, what could he do? What could the Fed do?
Tooze: What I think the Fed should announce is that it enthusiastically supports the idea of a bipartisan infrastructure push focused on the American electrical network, first and foremost, so that we can actually hook up the renewable-generating capacity—which is now eminently, you know, realistic in economic terms.
Setting a backstop to a a fiscal-side-led investment push is the obvious thing.

Meyer: So basically it should say: If the government were to issue a bunch of new debt to fund green investment and no one was buying it, then the Fed would?
Tooze: And there isn’t the slightest evidence [it wouldn’t sell], because the U.S. Treasury is issuing unprecedented quantities of debt right here and right now. But the Fed would view [the issue of new debt tied to infrastructure] as in no way alarming.
It is indeed a highly appropriate response to an environment of extremely low interest rates, and [former Treasury Secretary] Larry Summers & Co. would argue that it might help, as it were, to suck us out of the state of secular stagnation that we’re in.
Then you could get into the technicalities of thinking how the Fed addresses issues of finance and green bonds.
That would be another avenue to go down—for the Fed to take a role in helping develop a classification of green bonds, of green financing, with a view also to rolling out comprehensive demands for disclosure on the part of American firms, for climate risks to be fully declared on balance sheets, and for due recognition to be given to firms that are in the business of proactively preparing themselves for decarbonization.

Meyer: One idea that you mention in particular is that if there were some kind of green bond, it would count in some greater way against the amount of capital that banks are required to hold.
Tooze: Yes, exactly. Where it would really matter is that the Fed could work to modify Dodd-Frank regulation in such a way as to be supportive of that kind of lending, and the Fed could proactively work through the Basel process [which governs international bank rules] to make changes at the global level.
You could, for instance, declare that the Fed views with disfavor the role of several large American banks in continuing to fund coal investment.
Some of the carbon-tracking NGOs have done very good work showing and exposing the way in which some of the largest, the most reputable American banks are still in the business of lending to Big Coal.
Banking regulation could be tweaked in a way that would produce a tilt against that.

Meyer: Has the Fed ever done something like this before? Where it’s said, “We need to move the economy in this direction, so we’re going to treat certain asset classes favorably?”
Tooze: Yeah, this idea of neutrality comes up: Isn’t the Fed supposed to be neutral? It’s an attractive idea, and goes along with the idea of Fed independence—except it’s completely ahistorical.
I mean, the classic role of the Fed is to support government-issued debt. Insofar as the Green New Deal is a government-issued business, the Fed has just an absolutely historical warrant for supporting fiscal action. It hasn’t historically done that—and there’ve been moments where the Fed acted as a goad, notably in the early stages of the Clinton administration.
But with regards to the broader economy, the entire federal-government apparatus essentially stood behind the spread of home ownership in the United States and the promotion of suburbanization through the credit system.
And kind of what we need is a Fannie Mae and Freddie Mac for the energy transition.

Meyer: But without the crisis at the end of Fannie Mae and Freddie Mac, I guess.
Tooze: Of course. Fannie Mae and Freddie Mac became vehicles for truly toxic modes of leverage and intermediation.
But if the question is, Is there historical warrant for the financial agencies of government in the United States biasing the property structure in the economy in a certain way?, the answer is emphatically yes—all the way down to the grotesque role of the New Deal financial apparatus in enshrining the racial segregation of the American urban space, with massive effects from the 1930s onward.
The idea of neutrality should not even be allowed in the room in this argument. It’s a question of where we want to be biased. If you look at QE, especially in the U.K. and the EU, it was effectively fossil-biased.
[Editor’s note: Quantitative easing, or QE, is when central banks buy stocks and bonds to boost the economy.]
The assets that were bought as part of the asset-purchasing program had heavy carbon contact.
That’s not surprising: The bonds of the European energy majors have very high ratings, and so they tend to be part of the process of asset purchases.
So in the same way as QE is believed to have an effect on inequality through the way in which it drives asset-market prices, it also underwrites the existing biases of the financial system toward fossil fuels.
So monetary policy is not neutral with regards to the environment. There’s no safe space here. The only question is whether you’re going to lead in the right way.

Meyer: Last question. With any of this, is there a role for interested Americans to play if they are not particularly tied to the financial- or monetary-policy elite?
Tooze: Support your congressperson in doing exactly what AOC did in the hearings with Powell a couple of weeks ago.
[Editor’s Note: Representative Alexandria Ocasio-Cortez asked Powell whether inflation and unemployment are still closely connected, as the Fed has long argued.]
Applaud, follow with interest, raise questions. That’s exactly what needs to be happening. The politicization of monetary policy is a fact. I mean, I write these pieces because I personally think this is eminently suitable for political conversation.
If we don’t raise these questions, the de facto politics is, more often than not, conservative and status quo–oriented.
So this, like any other area, is one where citizens—whether they’re educated and informed or not—need to wise up, get involved, and follow the arguments and develop positions.
So applaud your congresspeople when they do exactly what AOC was doing in that situation. In many ways, I thought it was one of the most hopeful scenes I’ve seen in that kind of hearing in a long time.

Australia’s Climate Stance Is Inflicting Criminal Damage On Humanity

The Guardian |

The government opts for conflict rather than change, while suppressing details on the implications of its climate inaction
Australia is the most exposed continent to climate change, but remains in a state of climate denial and delay. Photograph: Reuters

  • David Spratt is research director of Breakthrough.
The top priority of government is security of the people. Yet on the greatest threat of all, most governments are failing abysmally.
As the global influence of western democracies wanes with the ascendancy of China, India and other emerging countries, the resulting power struggle is diverting attention from the great issues the world faces, to their symptoms.
The neoliberal market economy, with its unregulated consumption and rapacious short-term outlook, is destroying modern civilisation.
The warning signs are obvious, not least burgeoning high-consuming populations, massive biodiversity loss and multiple resource scarcities.
Yet rather than reform an unsustainable system, political leaders scramble to prop it up and compound the problem. The result is Brexit, Trump’s Mexican wall, escalating Middle East tension, the US-China trade standoff, a global arms and space race, Amazon deforestation and much more.
In their quest for power, leaders – both democratic and authoritarian – ignore the one issue that is inexorably changing that system, namely human-induced climate change. This is an existential threat to human civilisation that will render current political priorities irrelevant as climatic consequences move beyond human influence.
Countering this threat requires unprecedented global co-operation to initiate emergency action. Yet leaders opt for conflict, while suppressing information on the implications of their climate inaction.
In May, we published a short paper that included a simple 3C global warming scenario for 2050, outlining the hard-nosed practical impact of climate change, as opposed to more theoretical scientific and business risk disclosure situations.
This information was not new, but prompted extensive global discussion: some considered the situation entirely credible, others felt it too extreme. What became clear was the thirst for practical information of this kind.
In response, we recently published a follow-up analysis: “The Third Degree: Evidence and implications for Australia of climate-related security risk”, detailing the basis for our assumptions on issues such as chronic water shortages, coastal inundation, mass migration and extreme heat – plus an in-depth global 3C scenario originally published by US national security experts in 2007.
We also propose a major scenario-planning initiative for Australia. Scenario-planning does not forecast, predict or express preferences for the future; rather it is storytelling, painting pictures of alternative worlds that might emerge, to assist policymakers in imagining and thinking about future possibilities. Strategy is then assessed against each possible future.
One of the initial tasks is to identify the “official future” – the future as it is supposed to be, upon which prevailing strategy is based. A large amount of political capital is tied up in that view, typically the result of group-think generated by ideology or by business models that have stood the test of time but may be inappropriate in the future.
Scenario-planning explores the future, allowing constructive discussion on alternatives incorporating the full range of credible evidence. In particular, there must be a preparedness to think beyond conventional wisdom, after which a reassessment of the official future is often inevitable, and proactively undertaken.
Nowhere is this more necessary than in Australia, the continent most exposed to climate change, where the official future for the last two decades has been, and remains, climate denial and delay.
Political expediency, blinkered ideology and short-term business thinking rejects or deflects climate science and expert advice. Predatory delay is used to prolong the life of our high-carbon economy for short-term financial gain, irrespective of the damage to society. Policy, such as it is, views climate change as a non-problem.
The blatant inconsistency of Australia’s position beggars belief. We are signatories to the UNFCCC, supposedly committed to avoiding dangerous climate change, which is already happening. Australia ratified the Paris agreement to restrict temperature increase below 2C and ideally towards 1.5C, yet our emissions are rising rapidly even though there is no carbon budget remaining to stay below even 2C.
Incredibly, we ramp up new fossil fuel projects: Adani coal, gas expansion, fracking in NT and WA, and more. Then we have the gall to carry over unused carbon credits from the Kyoto protocol to obscure the failure of our wholly inadequate Paris emission reduction commitments; credits which were unjustified in the first place.
We are already the fifth largest carbon polluter globally when exports are included – about 5% of global emissions. On current projections, by 2030 Australia will be responsible for a massive 13% of global emissions. Our fossil fuel industries are subsidised annually by about US$29bn or 2.3% of GDP, far in excess of anything given to the low carbon industries.
And this in a country with probably the greatest low-carbon energy potential in the world – potential we are wasting, blocked by deliberately obstructive federal policy.
Australia’s climate stance is totally untenable in geopolitical terms, nothing less than a crime against humanity, as Pacific countries continually point out.
The federal government does its utmost to hide these facts from public view. Accordingly, Australia must undertake serious scenario-planning to inform the public of the criminal damage being inflicted upon them by their government, and to develop contingencies for emergency action as the official future of accelerating high-carbon growth inevitably falls apart in the near future.
The government’s role should be to protect the future from the past, not the past from the future. When government refuses to lead, others must.

Lost Cities And Climate Change

Scientific AmericanKate Marvel

Some people say “the climate has changed before,” as though that should be reassuring. It’s not
Remnants of the ancient city of Cahokia, in what's now southern Illinois. Credit: Steve Moses Flickr (CC BY 2.0)
Not far from my grandmother’s house is a ghost city. At Angel Mounds on the Ohio river about eight miles southeast of Evansville, there are a few visible earthworks and a reconstructed wattle-and-daub barrier.
 There is almost nothing left of the people who build these mounds; in a final insulting erasure, the site is now named after the white settler family who most recently farmed the land.
There are traces of other dead villages along the Ohio and Mississippi rivers, mounds scattered from present-day Indiana to Arkansas and Alabama.
In southern Illinois, a few miles from the Missouri border, hidden among empty corn and soy fields, is the center of that dead civilization’s gravity: the lost city of Cahokia.
Cahokia was larger than London, centrally planned, the Manhattan of its day. Most people there would have come from somewhere else. There were defensive foundations, playing fields, and a magnificent temple. There would have been sacred ceremonies and salacious gossip. It must have been a very exciting place to live.
And then, relatively abruptly, it ceased to exist. We know of the city only because of the physical traces left behind. Few stories of Cahokia have survived; it disappeared from oral tradition, as if whatever happened to it is best forgotten. The archaeological record shows traces of the desperation and bloodshed that almost always accompany great upheavals: skeletons with bound hands, pits full of strangled young women.
The North American Drought Atlas, a historical record of climate conditions pieced together from the rings of old trees, provides a hint of what might have happened. The tenth century CE, when the Cahokia civilization would have developed, marked a distinct shift in the regional climate from persistent drought to rainier conditions more suitable for agriculture, centralization, and civilization.
But the good times were not to last. In the middle of the fourteenth century, the climate swung back toward drought.
This shift was likely associated with shifting temperature patterns in the ocean that affected the jet stream, pulling cool air down from the Arctic and displacing rainfall patterns. These changes are attributable to some combination of natural internal climate variability and externally forced changes from solar activity and increased volcanic eruptions. Their effects were profound.
In Europe around the same time, a confluence of natural factors perhaps related and perhaps separate from the forces drying out the Mississippi Valley caused it to rain heavily in the summer of 1314. The rains continued into the winter, and then into the next year, and then the next. Crops rotted in the fields, and the entire continent went hungry. Contemporaneous historical records complain of rain and famine, villages forced to eat dogs and cats, the dead, and even each other.
The Old World Drought Atlas, a collection of European and Mediterranean trees, shows a period of persistent wetness around the beginning of the 1300s that corroborates these historical accounts. Many of us unwittingly remember the famines in the stories we tell our children. The fairy tale of Hansel and Gretel—hungry children abandoned in a forest haunted by a cannibal witch—almost certainly dates from this time.
Many historical events have happened against a backdrop of natural climate change. Drought in the steppes east of Hungary pushed marauding Huns west and toppled the Roman empire. Volcanic activity suppressed crop yields in pre-revolutionary France, leading hungry, desperate peasants to take drastic action. But climate is almost never the only factor in human history. The Roman empire was overextended and tenuous, torn apart as much by infighting and poor governance as outside enemies. The French underclass starved under the policies imposed by the overclass.
We humans are not passively dragged along by temperatures and rainfall patterns. Climate change did not cause the fall of Cahokia any more than it forced northern Europeans to eat their pets and abandon their children. But the adversity brought by climate change caused societies to break apart, magnified pre-existing divisions, and made desperate people easy prey for dangerous people.
“The climate has changed before,” say people who want to minimize the scale of the current challenge.
I have never understood how anyone could find this comforting. The natural climate changes that have shaped human history have almost always been smaller and more regionally contained than the large-scale human-caused change we are currently experiencing. And even these changes have provoked suffering, scapegoating, and the collapse of civilizations.
I am often asked what frightens me most about climate change, whether I lie awake at night thinking about ocean hypoxia or arctic permafrost or other feedback processes that could turn a bad thing into a catastrophe. I am scared of the physical changes that await us on a warming planet, but the most important feedback process is the least well understood.
The scariest thing about climate change is what it will make us do to each other.

'Quite Scary': Rising Temperatures Threaten Melbourne, Sydney's Water Security

Sydney Morning HeraldPeter Hannam

Sydney and Melbourne face rising threats to their water supplies from climate change as higher temperatures diminish inflows while pushing up demand, according to new research.
A paper published by Environment Research Letters shows a "substantially" amplified risk for Melbourne's water availability if global temperatures rise 2 degrees above pre-industrial levels rather than the 1.5-degree target set by the Paris climate agreement.

Separate research by the University of NSW into future rainfall and temperatures for some 222 catchments across Australia - some of which serve Sydney - found a marked increase in vulnerability of supply.“It’s quite scary actually," Ashish Sharma, a professor in UNSW's School of Civil and Environmental Engineering, said. "The implications for water security for this region are not good."
Warmer temperatures lift evaporation rates and dry out catchments, reducing the chance of the medium-sized floods that typically provide the great bulk of reservoir inflows in any one year, Professor Sharma said.
“It is a double whammy," he said. "You’re having a reduced access to water and increased water demand - hence the vulnerability, the security of the water system, reduce even more.”
Internationally, those moderate floods are expected to decrease at the rate of about 13 per cent each degree of warming, Professor Sharma said, noting that current carbon emissions trajectories point to a 3.5-degree increase by 2100.

Record warmth in 2019
The dams serving both Sydney and Melbourne are hovering just above 50 per cent, with the former's falling more rapidly in recent years than during the Millennium Drought earlier this century.

Desalination plants in both cities are ramping up. The Victorian government in April ordered its plant at Wonthaggi to deliver 125 billion litres for the 2019-20 year, while Sydney's Kurnell plant is nearing its full capacity of about 91 billion litres per year.The first seven months have also been the hottest on record for maximum temperatures for Victoria and the second warmest for NSW, the Bureau of Meteorology said.
Benjamin Henley - who studies water resource impacts from climate change at the University of Melbourne and the lead author of the research paper - said a warming world pointed to reduced rainfall in southern states.
“In the south, we’re likely to face a long-term drying trend under climate change, and it has almost certainly started," Dr Henley said.
Even so, his team's work showed that for Melbourne at least, there was a "distinct difference" in the impacts for water security if temperature rises were kept to 1.5 degrees rather than 2 degrees.
Lily D'Ambrosio, Victoria's climate change minister and acting water minister, said the warming was "a reality".
"We know we need to act now and plan for how we can better withstand increasingly high temperatures, reduced water availability, and the impact this has on the environment," she said.
Water efficiency measures, stormwater capture and making better use of sources independent of rainfall such as desalination, would be part of that planning, she said.
Fiona Smith, WaterNSW's executive manager water and catchment protection, said her agency was continuing to assess climate projections, noting some models projected increased rainfall.
"Research into climate change impacts are progressing but without conclusive findings accurate predictions for the east coast of Australia for water security purposes are not yet available," she said.

The Next Step In Fighting Climate Change

ForbesSteve Denning

Climate change is the crisis of our time.
As the human race sleepwalks its way towards a planetary calamity, there is a growing recognition of the need for a “moonshot” aimed at addressing the greatest existential challenge we have ever faced. The immediate problem is that a solid technical basis for such a moonshot does not yet exist. There is no audacious U.S. national plan in place to deal with climate change, quite apart from what other countries must do.
What we must now do is to create a fully empowered national climate change agency, devoted exclusively to climate change, with a mandate to prepare the carefully thought-through technical basis for an audacious action plan and with the political clout to make an impact.

How A Moonshot Happens
What is often forgotten in the celebration of America's space triumph of 1969 is that Kennedy’s speech of 1962, in which he inspired the nation to “go the moon by the end of the decade”, didn’t come out of the blue. In fact, the basis for it had already been laid in several distinct stages.
  • Stage 1: Pre-1958: Several competing agencies were striving for ownership of the American space effort: space: Army, Navy, Air force; there was no coherent national strategy, game plan or budget.
  • Stage 2: Creation of NASA in 1958: President Eisenhower established organizational clarity as to which agency was in charge of the space effort, but he didn't create the necessary priority or budget for the effort to succeed. It did nevertheless create the institutional and intellectual platform which provided the basis for the next step.
  • Stage 3: President Kennedy's 1962 speech articulated a clear national commitment to get to the moon before the end of the decade.
  • Stage 4: From 1962 to 1969, there was skillful maintenance and pursuit of the goal, through many difficulties, setbacks.
  • Stage 5: In July 1969, as promised, American men landed on the moon—an unparalleled feat of perseverance and ingenuity.
By way of comparison, the U.S. response to climate change is still in Stage 1: there are many ideas and studies, but no coherent national strategy, game plan, expert or political consensus or budget. The White House doesn’t even see that there is an issue. There are organizations and agencies producing studies and reports, but no mandate or urgency for action.

Stages of launching a moonshot. Steve Denning
Given the current administration, any major change in the situation will have to come in the next administration. Nevertheless, it is not too early to consider the necessary steps, beginning with a decision to take bold action.

Current Planning Is Inadequate
What’s happening now is sporadic, haphazard, ill-planned and tragically inadequate.
For example, as a sign of its commitment to climate change, Berkeley recently announced with pride that it has banned the use of natural gas in new low-rise buildings; this results in greater use of electricity generated by coal power plants with high pollution consequences.
Similarly, people may feel virtuous if they purchase electric cars, but the impact on climate change isn't clear if the cars are also using electricity generated by coal. Flailing away at climate change with symbolic actions that feel good and sound good but make no impact isn't going to get the job done.
Wind and solar are often presented as the keys to the future. Yet there is no coherent policy as to their future in the U.S. Wind and solar energy have few downsides per se but are not available 24 hours every day; Europe has found that dealing with the ups and downs of production can create practical problems.
A carbon tax is widely advocated by economists, yet the U.S. is one of the few large and industrialized nations that does not implement one. The basis for it is simple. Carbon emissions have an "unpriced" societal cost in terms of their harmful effects on the earth's climate. A tax on carbon would reflect these costs and send a powerful price signal that would discourage carbon emissions. Such a tax could have regressive income effects, but they could be alleviated by the way the resulting revenues are allocated. Carbon tax has a diverse array of advocates including Rex Tillerson, when he was CEO of Exxonmobil, the American Enterprise Institute, the Earth Policy Institute, and the Sierra Club, and the Washington Environmental Council. Yet no carbon tax is in place in the U.S. and none is even being seriously discussed.
Having an institution that is capable of thinking through the multi-sectoral issues involved in assessing the trade-offs, the inter-connections and the sequencing of different options and pushing ahead to action is going to be central to having any kind of real impact. At this point, there is not a single official at the highest levels of U.S. government who can speak sensibly on the subject.

Drawdown
Drawdown by Paul Hawken Penguin
The technical complexity of the choices facing us were brought home to me in reading Paul Hawken's interesting book, Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming (2017). It examines and prioritizes 80 ready-now climate-changing ideas, and quantifies their potential impact, along with 20 ideas that might materialize in the future, including direct air capture, hydrogen-boron fusion, autonomous vehicles, solid-state wave energy and living buildings. The ideas are listed in this summary table, along with their potential impacts from a global perspective.
The analysis contains quite a few surprises. Refrigerant management comes in at #1 while solar only ranks #8 and #10. Changes in household appliances doesn’t even make the top 80 options. Nor does natural gas make the top 80 options, even though the U.S. is leading the world in the reduction of CO2 through the conversion to natural gas. The question is not whether Hawken has everything right: his analysis shows the complex multi-sectoral nature of the issues. What does it all add up to?
On a “plausible” level of effort, the total amount of carbon dioxide avoided and sequestered is 1,051 gigatons by 2050, which is only two-thirds of what is needed to stop the increase of carbon dioxide in the atmosphere.
With a much greater level of effort, “the drawdown scenario,” the increase could be effectively stopped by 2050.
With an even greater level effort, the level of carbon dioxide could be reduced by 170 gigatons of carbon dioxide by 2050.
Options for dealing with climate change, from Drawdown by Paul Hawken Penguin
LARGE IMAGE
The book does not address the possibility that unless substantially greater progress by 2030, the opportunity for reversing the growth of greenhouse gases may close.
The book is helpful in mapping the territory of the options. “The overwhelming majority are no-regrets solutions, initiatives we would want to achieve regardless of their ultimate impact on emissions and climate, as they are practices that benefit society and the environment in multiple ways.”
It also notes several options for which we might have serious regrets if they were widely adopted, such as nuclear fission:
Nuclear [fission] is a regrets solution, and regrets have already occurred at Chernobyl, Three Mile Island, Rocky Flats, Kyshtym, Browns Ferry, Idaho Falls, Mihama, Lucens, Fukushima Daiichi, Tokaimura, Marcoule, Windscale, Bohunice, and Church Rock. Regrets include tritium releases, abandoned uranium mines, mine-tailings pollution, spent nuclear waste disposal, illicit plutonium trafficking, thefts of fissile material, destruction of aquatic organisms sucked into cooling systems, and the need to heavily guard nuclear waste for hundreds of thousands of years.
The book only paints the global picture: each country, region and community will have to make its own set of choices from the larger menu. Not all countries have tropical forests; sunlight and wind vary considerably. Obviously, some options would have greater impact sooner, if there was a greater level of effort.

The Issue Is Political And Technical
In one sense, the central issue is political. Summoning up the political willpower to do whatever is necessary to redress the situation, aggressively implementing the solutions that are ready for implementation, while exploring a whole slew of promising new technologies.
The U.S. needs to rediscover its pioneer spirit and once again become an international leader rather than a laggard. The fact that the current U.S. administration sleeps at the wheel and allows the country to careen towards an avoidable calamity need not prevent us from getting ready to take the necessary next step—the creation of a federal agency to lay the basis for a national effort to fight climate change, while also inspiring other nations to do likewise.
Thus in another sense the questions are also technical. Politicians are not climate scientists. They are not going to be the ones to sort out the massive complexities described by Paul Hawken in Drawdown. Nor should they be. The role of politicians is to endorse and communicate carefully thought-through technical policies and plans developed by a wide array of climate scientists, economists, sociologists and management experts, working together as outlined here.

A Different Kind Of War
Make no mistake, we are caught in a deadly war. Nothing will happen unless and until we grasp the magnitude of the challenge we face and share the belief that we have the technology, the smarts, the innovative capability, in effect the will to win the war.
The problem with this war is that the enemy is ourselves. As I described here, the core of the problem is that the burning of hydrocarbons is the foundation of many of the huge improvements in the material well-being of the human race over the last century. As a species, our brains have been created to ignore risks that appear distant in time and place. Countering human nature is hard. There are also many vested interests in maintaining the status quo.

Winning The War
Winning the war will require deep changes in consumption, technology, behavior, attitudes and education as well as radically increasing efforts institutional and social innovation. That’s why we need a moonshot.
A moonshot implies a change in mindset. It means a shift from accepting our fate as defined by events and taking things into our own hands, believing that we can and will change the future. It’s about looking beyond what we currently see and envisioning answers that may seem unreasonable—and pursuing them anyway. It’s about doing things that sound undoable but if done will redefine everything.
We don’t want or need a climate scientist as president. Nor do we need a candidate with a personally crafted, detailed climate plan. What we need is a leader who has the smarts to grasp the nature and magnitude of the challenge and mobilize action to deal with it. We need a leader who is able to inspire and lead us to win this war. The first and most urgent action is the creation of a fully empowered national climate change agency.
We have done monumental things before, whether it was the actual moonshot with NASA, the Internet with DARPA and the nuclear fission with the Manhattan Project. In each case through a coordinated national effort, we were able solve huge problems through innovation that led to radically new technical solutions that changed everything. As Astro Teller said, we were able replace apathy with audacity:
The seemingly impossible can happen when passionate and talented people come together with urgency and determination. The secret? It’s easier to get people to work on making something 10X better than to get them to help make it 10% better. Huge problems fire up our hearts as well as our minds. When you’re aiming for a 10X gain, you have to find whole new ways of doing things, and lean on bravery and creativity — the kind that, literally and metaphorically, can put a person on the moon.
The space race was valuable far beyond its original goal: NASA’s work has led to dozens of technology breakthroughs with many everyday uses, and inspired generations of kids like me to fall in love with science and engineering. When the world’s problems make us feel small and helpless, we should reflect on the lessons the Apollo missions hold about human nature, and our ability to choose bravery over fear and set aside apathy in favor of audacity.
The State Of The Current Political Debate
Listening to the debate among politicians about climate change today—or more often, the absence of debate—can be dispiriting. It brings to mind the poem written by W.H. Auden in 1939 at a time when a different kind of global crisis was in the offing.
Intellectual disgrace
Stares from every human face,
And the seas of pity lie
Locked and frozen in each eye.
Creating another federal agency may not seem like a big deal. The day that we create such an agency the world will go on as before. It will be seen as something plodding, mundane, even boring. Only a few that think of it as day as one in which we did something unusual: a day that lays the basis for securing the future of the human race. Nor should there be any beating of drums or great celebration. The real work will still be in front of us. But something will have begun.
Having an agency in place won’t solve the problem by itself. Periods of blistering heat and extreme weather events will continue to afflict us for years to come. But something significant will have begun. We will have created the basis for unlocking the hidden talents and aspirations of the human race to preserve the beauty of our world for our children and our grandchildren. As Auden said:
In the deserts of the heart
Let the healing fountain start.

Climate Change Visible From Space Station

Canberra Times - AAP

Italian Luca Parmitano (top) was sent to the ISS on July 20 along with two other astronauts.
Astronaut Luca Parmitano has warned he has seen the ravages of the climate crisis from the International Space Station.
The Italian engineer, of the European Space Agency, spoke about the issue during a press conference from the space station.
He said that changes in the appearance of the planet are noticeable from the satellite, which orbits 408 km from Earth.
"From the ISS we can make human observation and what I can say is that I have seen in my photographs and those of my companions in the last six years authentic changes," he added.
"I have seen deserts move forward and glaciers melt."
He said he will continue sharing photos on social media and warning people about the problem.
"I hope that our words and view can be shared to alarm people and really warn about the number one enemy today: global warming," he added.
"I don't know if it is possible to reverse it, but we must do everything possible to reduce and stop it."
Parmitano gave his first press conference since his arrival at the orbital station a week ago.
It is his second time on the habitable satellite after his first mission, Volare, in 2013.
The 42-year-old has been put into orbit as part of the Beyond mission, which includes experiments to pave the way for future space exploration, such as returning to the Moon or an expedition to Mars.
Parmitano was sent to the space station with American Andrew Morgan and Russian Alexander Skvortsov on July 20.
He will spend two hundred days in zero gravity and during the second half of the mission will be in charge of commanding the orbital laboratory, the first Italian to do so.
