Climate Change Also Wiped Out Life On Earth 252 Million Years Ago

In addition to detailing the demise of Permian-era life, the new research can be used to better understand the impacts of warming ocean temperatures on modern species.

Some 252 million years ago, nearly all live on Earth vanished. The fossil record suggests some 96 percent of all marine life disappeared, and scientists suspect the magnitude of losses on land was similar.
But until now, scientists weren't sure what exactly caused the massive Permian Period extinction, an event known as the Great Dying.
Researchers knew a series of volcanic eruptions set off a devastating chain of events, including deadly and disruptive climatic and environmental changes, but scientists couldn't agree on a smoking gun.
Was it the sudden rise in ocean acidity? Did sulphur and other toxic metals poison the seas? Or did sudden rises in ocean temperatures wipe out almost all marine life?
New models designed by scientists at the University of Washington and Stanford University suggest a rapid rise in ocean temperatures was to blame. According to the complex simulations, the warming event accelerated the metabolism of ocean species at the same time that oxygen levels dwindled. The planet's marine animals quickly ran out of oxygen -- asphyxiation on a massive scale.
Researchers designed models both to predict the impacts of massive volcanic eruptions on ocean temperatures and to simulate the impacts on marine animals.
To ensure the accuracy of their models, researchers simulate the precise arrangement of the ancient supercontinent Pangea.
"The Earth system model we used predicts the exchanges of energy, mass, and momentum between the ocean and atmosphere," Justin Penn, a doctoral student in oceanography at Washington, told UPI in an email. "It was formulated to simulate the end-Permian by joining the continents into the unified landmass from around 250 million years ago, known as Pangaea."
"We increased atmospheric greenhouse gas levels in the model to cause ocean warming and oxygen loss," Penn said. "The tolerances of marine animals to these changes were used to quantify their impacts on marine life. They were estimated by using published lab measurements of these traits in modern species."
The models tell a story of deadly warming, but most importantly, the models showed where marine warming would have been most dramatic and had the deadliest impact. The simulations also predicted where certain species would become isolated as the oceans continued to warm and oxygen levels dropped.
Animals in the tropics would have been better adapted to warm-water, low-oxygen conditions, and could move toward to the poles as the oceans warmed. Species living farther from the tropics, according to the simulations, were the first to disappear. The fossil record matched the model's predictions.
"The warming and oxygen loss simulated in the Earth system model match the changes implied by geochemical data from end-Permian age rocks, indicating realistic magnitudes of model climate change," Penn said. "In particular, the observed temperature of the ocean at the end-Permian is reconstructed from the chemistry of the teeth of eel-like creatures that lived during the extinction."
It's the first time scientists have successfully tested the results of a Permian-era extinction model against the fossil record. Scientists described their feat in the journal Science.
In addition to detailing the demise of Permian-era life, the new research can be used to better understand the impacts of warming ocean temperatures on modern species. According to the authors of the new study, by the end of the century, Earth's oceans will have warmed 20 percent as much as the Permian-era warming. While some species will be able to adapt, others are likely to disappear, just like their Permian relatives.
"Species more tolerant of warm, low oxygen conditions are more likely to adapt to these conditions when they arise under global warming," Penn said. "In contrast, species that require cold water and/or high oxygen levels are more at risk because those habitat conditions become more rare in a warming climate."

Lightbulb Group Shows Way On Climate Change

Financial Times

Transition to LEDs is one example of disruption across industries battling fossil fuels


To understand the disruptions of climate change on industry, consider the humble lightbulb. Twelve years ago, when Philips Lighting was considering the shift from incandescent lightbulbs to the much more efficient LED lights, the company faced an uphill battle.
“I had to do as much internal lobbying as external, because two-thirds of our sales volume was incandescent lightbulbs,” recalled Harry Verhaar, head of government affairs at Philips Lighting, the biggest lighting company in the world that is now known as Signify.
The shift in lighting has profound consequences for energy consumption: in 2006 lighting accounted for one-fifth of global electricity demand.
But as lighting has become more efficient, that figure has dropped to 13 per cent today, and will fall to 8 per cent by 2030, according to Mr Verhaar.
The transition to LEDs is just one example of the disruption taking place across industries, as governments around the world try to reduce emissions by improving energy efficiency and cutting reliance on fossil fuels.
The impacts of climate change have become much more visible in the past year, in terms of direct physical impacts such as hurricanes and wildfires, and in policy impacts from climate-related legislation, such as rules encouraging efficient lighting.
And companies are taking notice like never before.



As in any great disruption there are set to be winners and losers from this change, and the Financial Times will examine some of the industries that will be most affected in its series, Climate Control. For Signify, the low-carbon transition has meant a surge in sales of LEDs, which now constitute about 70 per cent of its revenues, while incandescent sales globally have plummeted.
“Everybody saw that, if you don’t cannibalise your own business, somebody else will,” said Mr Verhaar.
Many other sectors are in the middle of similarly disruptive shifts as the world shifts to a low-carbon economy, and corporate boards and investors are increasingly trying to understand what this change will mean for them. The approval of the Paris climate agreement in 2015 was a key trigger, as nearly 200 governments pledged to limit global warming to less than 2C, sparking a series of related policy changes.
Mentions of climate change-related keywords in corporate earnings calls jumped after the Paris accord was approved, with 70 per cent more mentions in the three years following the agreement, than in the three years preceding it, according to a transcript analysis prepared by S&P Global for the FT.



What used to be the provenance of the marketing department or the sustainability team has become a core part of corporate planning in many sectors.
“It has been a huge transformation, from completely ignoring [climate change], to dealing with it in the CSR or marketing department . . . to becoming a major strategic issue for many companies,” said Nigel Topping, chief executive at We Mean Business, a non-profit organisation.
“In quite a lot of sectors it is a big strategic issue that is not even called ‘climate change’,” he added.
From the rise of electric vehicles, to the heavy industries trying to cut emissions, the global response to climate change is starting to have a big impact.
In the oil and gas sector, one of the major stories of 2018 has been the new climate targets announced by BP and Royal Dutch Shell.
Ten years ago it would have been unthinkable that the biggest oil and gas companies in the world would pledge to cut their emissions.
In a signal of how seriously regulators are starting to take this issue, the Bank of England in October told banks and insurers to improve their long-term planning for climate change — placing senior executives in the line of fire if they failed to do so.



The world has already warmed by 1C compared with pre-industrial times, which has contributed to record-breaking wildfires this year and increasingly frequent heatwaves.
For insurance companies dealing with seafront real estate, to the electric utilities that must make sure their grid can withstand large wildfires, the physical impacts of a warmer world have become impossible to ignore.
A landmark report in October by the Intergovernmental Panel on Climate Change outlined how even half a degree of additional warming — the difference between 1.5C and 2C of warming — would expose an additional 420m people to heatwaves, and an additional 10m people to rising sea levels.
If current trends continue, the world will be 3C warmer by the end of the century, a level that would disrupt life around the planet.
Another catalyst for the way companies view climate risks came last year, when the Financial Stability Board published a set of guidelines from its Taskforce for Climate-related Financial Disclosures (TCFD) about how banks and companies could disclose climate-related risks.
Charles Donovan, head of the centre for climate finance at Imperial College London, said that the TCFD “helped enormously” by providing some common standards.

“We’ve all gotten on the same page of what we are talking about,” due to the TCFD, he said, but added that there was still a way to go.
“There is a lot of information out there, but nobody has really settled down on what is the information that moves the needle on value.” Because this is a relatively new field, it is still very difficult for companies, investors and regulators to fully grasp and measure the impacts that climate change will have.
A recent scientific paper in Nature Climate Change found that more than 80 per cent of companies surveyed said they faced physical risk from climate change — but only one in five were able to quantify the related financial risk.
“It’s almost incomprehensible, the range of how this one thing [climate change] is physically manifest in the world.
And it has really practical implications, in terms of how it affects companies,” said Allie Goldstein, lead author of the paper.
Of the 2,000 companies surveyed, more than half said they expected costs to rise as a result of climate change.
A new field of financial analysis has recently sprung up that tries to better quantify the risks — and the potential impact on corporate valuations.
“The climate change topic in the financial sector is still in its very nascent phase,” said David Lunsford, one of the co-founders of Carbon Delta, a boutique analysis group focused on climate risk.
“There is definitely bad data out there, and I feel strongly about it.
The fact is that if you look at industrial activity and the reporting of greenhouse gas emissions you find major flaws.”



The earliest models of climate risk took a company’s emissions of carbon dioxide and multiplied that by a hypothetical carbon tax to gain an estimate of the impact of climate-related policies.
However, this approach has largely been discarded, because carbon pricing has so far been lower than expected in most countries, and because it does not take physical risk into account.
“Carbon footprinting is a useful exercise, but it is not a risk metric,” said Mr Lunsford.
Groups like Carbon Delta incorporate emissions estimates, along with regulatory analysis and patent data to calculate the potential impact on companies’ market cap from different levels of global warming.
“It’s very difficult to calculate the costs or the profits from a climate change scenario [like 2C or 3C] but that is where the whole industry is headed eventually,” he added.
Paul Simpson, chief executive of CDP, the non-profit that helped kick-start corporate disclosures of emissions when it was founded 18 years ago, said that one reason modelling was so difficult is that “we know the future won’t be like the past”.
“There are a lot of initiatives going on to produce better research,” he said.
“Certainly on the data side, we don’t just want more data, we want better data.”

This Is What Happens To Australia If We Don’t Act

NEWS.com.au - Charis Chang

Australia has put this issue in the too hard basket but it will come back to bite us. This is what happens if we don’t do anything.

This year Australians have suffered through one of the worst droughts in living memory, bushfires and a heatwave that saw hundreds of flying foxes “boiled alive”.
It also saw the publication of one of the most comprehensive reviews of climate science which delivered a “wildly alarming” report about where the world was headed.
Yet Australia still does not have a climate change or energy policy.
This week there was an extraordinary act of rebellion from NSW Liberal Energy Minister Don Harwin, who used an opinion piece in the Australian Financial Review to accuse the Morrison Government of being “out of touch” on climate and energy policy.
Perhaps some of the doom and gloom from recent reports into the world’s changing climate is finally starting to filter through?
Climate change is certainly being taken seriously by many Australians, with the Climate of the Nation report this year showing the number of Australians concerned about it had reached a five-year high.
The report produced by The Australia Institute found 73 per cent of 1756 Australians surveyed were concerned about climate change, up from 66 per cent in 2017.
But Federal Energy Minister Angus Taylor has hit back at pressure from Mr Harwin and other states and territories who want higher emissions reduction targets, suggesting they need to “get back to reality”.
So what is the reality on climate change? Here are some facts.

Australia has warmed by 1 degree
On Thursday a new report was released that confirmed Australia had already warmed by 1C since records were first kept in 1910, according to the State of the Climate, a joint analysis released by Australia’s Bureau of Meteorology and CSIRO.
As well as a spike in the number of extreme heat days, oceans around Australia seem to be warning and this is contributing to a rise in sea levels, CSIRO director of the Climate Science Centre Helen Cleugh said.
The report confirms the findings of the “wildly alarming” Intergovernmental Panel on Climate Change (IPCC) report, which also noted the world had warmed by 1C.

We’re on track for 3 degrees
The IPCC report has been hugely influential because it looked at 6000 peer-reviewed studies and involved 91 authors and review editors from 40 countries.
It found current pledges made by countries around the world — including Australia’s target to reduce emissions by 26 to 28 per cent on 2005 levels by 2030 — would see temperatures rise by 3C by the end of the century.
Scientists and climate activists have called on countries to ratchet up their carbon-cutting pledges as soon as possible.
Actions taken in the next 12 years until 2030 will be critical in order to have a chance of keeping global warming to 1.5C.
Temperatures are likely to rise by 1.5C between 2030 and 2052 if they continue to increase at the current rate.

We’ll lose the Great Barrier Reef
The future is bleak for one of Australia’s biggest tourist attractions, which is estimated to be worth $56 billion to the country.
The IPCC report found that if the Earth warmed by 1.5C, most of the world’s coral reefs would be lost in the next 30 years, although some would survive.
Half the world’s coral reefs could be saved if warming was limited to 1.2C.
“This is worth fighting for,” coral reef expert and Australian Marine Conservation Society (AMCS) adviser Dr Scott Heron said.
If there was 2C warming, virtually all the world’s reefs would be gone from 2050 onwards.
A Deloitte Access Economics report found Australia’s Great Barrier Reef currently supported 64,000 full-time jobs.

Extreme heat, less rainfall
The fire season is now months longer than it used to be in some areas, Bureau of Meteorology climate monitoring manager Karl Braganza said.
The State of the Climate report released this week indicates Australia should get used to horrific bushfire seasons that rage at greater intensities and for much longer periods of time.
There’ll be more potentially catastrophic “fire weather” based on hot daytime temperatures, wind speed, humidity and the state of the fuel.
The combination of reduced rainfall — down 20 per cent since 1970 — and higher temperatures will see extended periods of drought become more common, the CSIRO’s Helen Cleugh said.
It’s not just people who will be impacted by more frequent extreme weather events, in January this year, hundreds of baby flying foxes were “boiled alive” when temperatures soared to 47.3C in Sydney’s west.
Flying foxes from the Campbelltown colony in Sydney’s west were ‘boiled alive’ during extreme temperatures.

Sea level rise
The IPCC said sea levels were expected to rise by 0.26m to 0.77m by 2100 (compared to 1986-2005) if there is global warming of 1.5C.
It will be 0.1m higher if temperatures rise by 2C and an extra 10 million more people would be exposed to climate risks at this higher level of warming.
Maps on Coastal Risk Australia show the impact of a 0.74m rise in sea levels, with large areas of Bryon Bay, Cairns and Port Douglas underwater. Parts of Melbourne’s Southbank precinct would be submerged along with Sydney’s Woolloomooloo and the eastern suburbs.

Extreme measures necessary
It’s possible for the world to keep warming to 1.5C but extreme measures will be necessary.
Around the world the use of coal to generate electricity would virtually have to be eliminated by 2050 as part of all the scenarios the IPCC modelled.
This would also need to be combined with other measures such as carbon dioxide removal, changes to agriculture and forestry land use, as well as bioenergy with carbon capture and storage.
Carbon emissions would need to be cut by 45 per cent from 2010 levels by 2030. This would allow carbon emissions to reach “net zero” by around 2050.
If temperatures were allowed to rise above 1.5C it would take a lot more effort to bring this back down by 2100. Techniques to remove carbon from the air would probably have to be used and their effectiveness have been unproven at large scale. Some of them may carry significant risks for sustainable development, the report notes.
A separate report on The Economics Of 1.5C Climate Change found the world needed to act now if it didn’t want to turn to risky or expensive measures to block out sunlight.
New “climate engineering” technology may eventually be necessary and this could include “solar radiation management” which involves deflecting sunlight to reduce warming.
Methods include stratospheric aerosol injections, marine cloud brightening, space mirrors and painting roofs white.
Aerosol injections involve spraying aerosols into the stratosphere so that the particles block and reflect the sun’s rays, to bring temperatures down.
Marine cloud brightening works in a similar way and involves seeding clouds with a fine spray of saltwater to encourage micro-droplets to form. These micro-droplets scatter incoming radiation and make clouds last longer.

What australia is doing
Despite warnings that coal-fired electricity would have to be phased out by 2050 to keep warming to 1.5C, the Morrison Government still wants taxpayers to back new coal projects as part of its Underwriting New Generation Investments program.
Meanwhile businesses and other organisations are calling for the Government to adopt a climate change policy after former prime minister Malcolm Turnbull’s National Energy Guarantee was dumped.
Australia’s greenhouse gas emissions have climbed 1.3 per cent to their highest levels in eight years, although Prime Minister Scott Morrison says the country will meet its Paris emissions reduction target.
Figures released on Friday showed Australia wasn’t on track to meet its 2030 emissions target it will use an accounting trick to play catch-up.
The United Nations Emissions Gap Report published in November also showed Australia was not on track to meet its Paris target.
“There has been no improvement in Australia’s climate policy since 2017 and emission levels for 2030 are projected to be well above the NDC (nationally determined contributions) target,” the report noted.
“The latest projection published by the Government shows that emissions would remain at high levels rather than reducing in line with the 2030 target.”
This week Mr Harwin tried to get state and territory energy ministers across Australia to discuss putting a roadmap towards net zero emissions by 2050 into a national energy policy at a meeting in Adelaide.
But Federal Energy Minister Angus Taylor refused to add it to the Council of Australian Governments agenda.
“We should be talking about getting prices down, keeping the lights on, making sure we’re keeping manufacturers in business … not talking about higher targets when we know we’re doing well,” Mr Taylor said.
“It’s time that those in those Labor states and others who are arguing for these crazy targets, reckless targets, get back to reality, talk to some real people, and get on with the job of doing the real work.”
Labor has said it would not support new coal projects and has a 45 per cent emissions reduction target by 2030 and 50 per cent renewable energy target.
It looks like it will be up to the Australian people to decide what they want.

Parenting The Climate Change Generation

New York Magazine

A family sits along the shore of Lake Elsinore as they watch the Holy Fire burn in the distance, in Lake Elsinore, Calif. More than a thousand firefighters battled to keep a raging Southern California forest fire from reaching foothill neighborhoods. Photo: Patrick Record/AP/REX/Shutterstock

Earlier this month during Art Basel Miami Beach, at a cocktail party held just inches above Biscayne Bay, an art collector was describing the ordeal of his year of house hunting. He was one half of a well-off, middle-aged gay couple raising two children and hoping to find a place calmer than New York for their kids’ adolescence and their own semi-retirement. Their first choice, he said, was Montecito, the richest part of Santa Barbara County, but then the broker who’d been helping them there died in last December’s mudslides. They decided they couldn’t go back. They looked at a few houses in Malibu — “but they all burned down.” In the end, they chose Miami. “You know climate change is coming for South Florida, too, right?” someone asked. “At least it’ll be slow,” the collector replied, clearly having thought about it. With a hurricane, you get at least a few days’ warning, he said, and with sea-level rise, years. “Then, it’ll just be like Venice.”
As recently as a few years ago, this was not the way the wealthy tended to talk about the dilemmas of child-rearing. As much as Americans may have feared the wrath of global warming, we assumed that most of us would be spared its most brutal impacts, by the prophylaxis of our collective wealth, and that the very richest among us might be able to shield themselves entirely. But that’s changing. The Kardashians may have hired private firefighters to fend off this fall’s Woolsey fire, but millions around the country watched the same family evacuate via Instagram Story, too.
If the country’s plutocrats are now scrambling to secure their lives from climate change, terrified about what it will mean for the future of their families, where does that leave the rest of us? Over the last year or two, the question I’ve been asked more than any other by people who know I write about warming concerns kids: whether it’s moral to reproduce in this climate; whether it’s responsible to have children; whether it is fair to the planet or, perhaps more important, to the children.
As it happens, earlier this year, my wife and I did have a child, Rocca, after several years of “trying.” In other words, when we first conceived of conceiving a child, it was in relative ignorance about warming; like many Americans, we knew about climate change in a sort of theoretical way, but thought that the threat of it ended roughly at the shoreline, and that we could go on living our lives as we always had, without worrying too much — trusting that others, “in charge,” would fix it. By the time we’d actually conceived, we were no longer under that illusion, thanks to unprecedented hurricanes and wildfires and floods, and the year or so I’d spent buried in the dark news from climate science. By the time Rocca was born, the news had grown grimmer: studies predicting deaths from air pollution in the tens of millions, and cities in India and the Middle East made uninhabitable by direct heat as soon as 2050. In the nine months since, it has grown grimmer still: a global, lethal heat wave this past summer, the worst wildfires in California history, the “doomsday” IPCC report warning that the world had only 12 years to cut carbon emissions in half, or risk true climate catastrophe.
This is, as unhappy as it may be to believe, not an unusual accident of the year or month in which our daughter was born. Take any chunk of nine months over the last decade and the picture of climate change is sure to have darkened in that time. Take any chunk of nine months in the future and the same is likely to be true. Extend the chunk of time to the length of a childhood, or a full life, and that picture of climate suffering gets dramatically worse. Should we stay the present course on emissions, Rocca will probably live to see a world in which certain places could be struck by six climate-driven natural disasters simultaneously and global damages from those climate impacts could pass $600 trillion — more than double the amount of wealth than exists in the world today. More than a hundred million would be dead from air pollution, and a hundred million more made homeless by heat, drought, and flooding. The pressure on our politics would be, by any standard we’d use today, too much for the system to bear.
You might expect these premonitions to settle like sediment into family planning. And indeed, among the young and well-off in Europe and the United States, for whom reproductive choices are often freighted with political meaning, they have. Among this outwardly conscientious cohort, there is worry about bringing new children into a damaged world, full of suffering, and about “contributing” to the problem by crowding the climate stage with more players, each a little consumption machine. “Want to fight climate change?” the Guardian asked in 2017. “Have fewer children.” That year and the next, the paper published several variations on the theme, as did many other publications delivered to the Western bourgeois, including the New York Times: “Add this to the list of decisions affected by climate change: Should I have children?”

The effect on the personal choices of the consumer class is perhaps a narrow way of thinking about global warming, though it demonstrates a strain of strange ascetic pride among the well-to-do. “The egoism of child-bearing is like the egoism of colonizing a country,” the novelist Sheila Heti writes, in a representative passage from Motherhood, her meditation on the meaning of parenthood, which she chose to avoid. But that ascetic pride takes a lot of forms, including demonstrations of stoicism in the face of suffering you believe will be quite profound — for you and your children. “A world of extinction and catastrophe, a world in which harmony with nature had long been foreclosed,” is how the author Roy Scranton described the scale of that suffering, in “Raising My Child in a Doomed World,” an essay published in the Times last July. “My partner and I had, in our selfishness, doomed our daughter to life on a dystopian planet,” he wrote, “and I could see no way to shield her from the future.” The piece was quickly criticized, by climate activists, for being too eager to declare an endgame for warming; critics also came for “It’s Okay to Have Children,” in which Jacobin’s Connor Kilpatrick argued against the wave of natalist fatalism.
Others wrestle with different questions — not whether to have children in a time of global warming but how to talk to them about it. One climate writer I know has, in the last few years, taken his teenage children to see the Great Barrier Reef, which was once a natural wonder of the world, with the complexity of a great city, and which is now inarguably dying, and Glacier National Park, so named because it once held 150 glaciers; today all but 26 have melted. It’s a beautiful gesture, almost mythological — a parent giving a simultaneous tour of the past and the future to his children. But there are also those parents I know who wonder whether it would be better to spare their children memories like that, memories that will be carried forward for many decades as reminders of what has been lost — or, rather, destroyed. One scientist and mother recently described the book she was working on to me as “Between the World and Me meets The Road.” And when you find your young child crying over a treacly photograph of a skinny polar bear stranded on a tiny melting ice floe, do you tell her the tragedy is far away, in the Arctic; that the world is a complex place, that nature has always been a theater of cruelty, and that the fate of one polar bear is not a reason to shed tears; that it’s a distraction from the climate crisis faced already by millions of people the world over, with whom she might feel a stronger kinship; or that, however trivial and marginal, it is still a powerful sign of the further degradation to come?
Here is what I plan to say, when Rocca is old enough to ask: Further degradation isn’t inescapable, it is optional. That is what I say today, when people ask me about children, including my own — wondering how my wife and I could have even countenanced having a kid, given all we know to fear about the future. But each new baby arrives in a brand-new world, contemplating a whole horizon of possibilities. The perspective is not naïve. We live in that world with them — helping make it for them, and with them, and for ourselves. A new clock starts with every birth, measuring how much more damage will be done to the planet and the life the child will live on it. The horizons are just as open to us, however foreclosed and foreordained they may seem. But we close them off when we say anything about the future being inevitable. What may sound like stoic wisdom is often an alibi for indifference.
Part of our choice was delusion — the same willful blindness that allowed us to grow into our mid-30s, in America, mostly blind to the way our lives and purchases and travel and diets were polluting the futures of our children and their children, and indeed the futures of everyone they might ever meet on this planet. I now know there are climate horrors to come, some of which will inevitably be visited on my kids — that is what it means for warming to be an all-encompassing, all-touching threat. But I also know that those horrors are not yet scripted. We are staging them by inaction, and by action, can stop them. Climate change means some bleak prospects for the decades ahead, but I don’t believe the appropriate response to that challenge is withdrawal, surrender. I think you have to do everything you can to make the world accommodate the life you want to have for yourself, and your family, rather than giving up early, before the fight has been lost or won, and acclimating yourself to a dreary future brought into being by others less concerned about climate pain. The fight is, definitively, not yet lost — in fact will never be lost, so long as we avoid extinction, because however warm the planet gets, it will always be the case that the decade that follows could contain more suffering or less.
And I have to admit: I am also excited for everything that Rocca and her sisters and brothers will see and do. Yes, she will hit her child-rearing years around 2050, when we could have climate refugees in the many tens of millions; and, yes, she will be entering old age at the end of the century, the end-stage bookmark on all of our very bleak projections for warming. In between, she will watch the world doing battle with a genuinely existential threat, and the people of her generation making a future for themselves, and the generations they bring into being, on this planet. And she won’t just be watching it, she will be living it — quite literally the greatest story ever told. It may well bring a happy ending.

Nine Energy Stories Will Drive 2019 -- Many Of Which Will Be Powered By Trump

Forbes - Ken Silverstein

White House Getty
2018 has once again been underscored by the loudest guy in the room, or in this case, the world: Donald Trump. 2019 will only ramp up the volume. But the noise, though, is getting more obnoxious while his words and actions have become inescapable. Indeed, the president is described as a con artist. And his energy and environmental policies are just as dirty — a throwback to a bygone era when the milkman delivered and the gas station attendant pumped your gas.
Setting aside Trump’s personal peccadilloes, he has tried to totally turn back Obama’s environmental policies. There’s also Trump’s indifference toward CO2 emissions and his denial of climate science as well as his attempted reversal of vehicle tailpipe emissions standards. And then there’s the try at propping up of uneconomic coal-fired power electricity as well as the proposal to ease natural gas-related methane emissions. The list goes on.
But Trump’s biggest faux pas this past year has been his misguided insistence that the U.S. must apply tariffs on certain products coming out of China and namely, solar panels. To this end, solar development in the United States is feeling the heat. Meantime, China has responded in-kind and it has specifically targeted oil and natural gas exported from the U.S. And once China gets locked into new long-term contracts, the U.S. could be frozen out of these lucrative markets.
Just as former White House Counsel John Dean warned the nation in 1973 that a “cancer was on the presidency,” a similar malignancy may now be upon us in 2018. But this column will drill down on Trump’s policies, which could stick around a lot longer and which could have a far-reaching impact.

Nine: On a positive note, the shale gas revolution continues to provide both economic and environmental opportunities. When it comes to using natural gas for electric generation, the fuel is replacing coal. And that is helping to drive down CO2 levels, which are tied to global warming. The good news is that CO2 emissions are 18% less than they were in 2005, says the Energy Information Administration.
And when it comes to shale gas and its byproducts being used for the manufacturing process, that too is giving a boost to regions of the country that need a second wind: Appalachia, in particular.
In fact, a 2018 study says that the Utica and Marcellus Shale basins will provide 37% of the nation’s natural gas production by 2040, making it the best place nationally for manufacturers to invest — even better than the Gulf Coast. IHS Markit concludes that the region, which is made up of Ohio, Pennsylvania and West Virginia will “provide a significant financial advantage” when compared to the Gulf Coast.

Eight: But the negative side of greater shale gas exploration means the potential for more methane leaks, which are 80-times more powerful than CO2 and which are also responsible for trapping heat. In 2000, shale gas accounted for 5% of all gas production in the United States and today it is about 60%, according to U.S. Energy Information Administration.
With that, a 2018 study published in the journal Science says that the U.S. oil and gas business emits 13 million metric tons of methane from its operations a year. And that is 60% more than the U.S. Environmental Protection Agency has estimated. In fact, the leak rate from existing operations is 2.3%, which is greater than EPA’s estimate of 1.4%. Despite the serious concerns and the available technologies, Trump’s Environmental Protection Agency released a draft to ease up the time frame for which oil and gas companies must inspect and fix their leaks for fracking sites on publicly-held lands.

Seven: The states are on the leading edge of enacting policies to curb emissions and especially CO2. One idea to emerge — and a lot of environmentalists don’t like it — is the one to save the existing nuclear energy fleet. Right now, 99 nuclear reactors provide about 20% of the nation’s electricity and 56% of its carbon-free power. At the same time, the industry says that its operating costs have fallen by 19% since 2012.
But six plants have shut down over the last five years, either the result of safety issues or the fact that they have been unable to compete with cheap natural gas generation. To help save those plants, New Jersey enacted laws to keep open PSEG’s Salem and Hope Creek nuclear plants operating.
It follows Connecticut, which is working to save Dominion Energy’s facility. Ohio and Minnesota are in the process of doing the same for First Energy and Xcel Energy, respectively. Those states follow Illinois and New York, which enacted laws to credit nuclear units owned by Exelon and Entergy, respectively, for the clean energy they generate.

Six: In 2009, car makers had agreed with President Obama to produce vehicles that got better gas mileage. But they had a change of heart once President Trump was sworn in. They have now given the Trump administration their blessing to reverse course: instead of the 54.5 miles per gallon that Obama would require — over-and-above the current 35 mpg — Trump has settled on 37 mpg by 2025.
But California is responding by saying that the tougher vehicle emissions standards set by the Obama administration only add a few hundred dollars to the price of a new car and that has not deterred consumers who finance them over five years. It, along with nine other states, will fight the Trump administration in court.
The silver lining here is that automakers are committed to commercializing all-electric models. Indeed, at least 13 companies have such brands, including Tesla, Volkswagen, Nissan, BMW, Mercedes-Benz, General Motors, Ford and Toyota.
According to U.S. the Energy Information Administration, electric vehicles are now 1.6% of the overall car market. But that could increase to 6% in 2025.

Five: While experts predict that electric batteries for cars will hit stride around 2027, battery storage for utilities got a big boost in 2018. Wind and solar energies have been responsible for about 60% of all of generation. That has caught the eye of electric utilities.
Xcel Energy, which has a goal of going fully renewable by 2050, says that it can do do so without huge burdens on its customer base. To that end, it has asked for energy storage proposals that could help bolster its would-be wind and solar projects. It got 430 such bids, compared to 55 in 2013.
The U.S. Energy Storage Monitor 2017 Year-in-Review says that 1,000 megawatt-hours of that capacity was deployed between 2013 and 2017 and it is predicting that more than 1,200 megawatt-hours of energy storage will get deployed in 2018 alone; last year, it was 431 megawatt-hours.
Moreover, the Federal Energy Regulatory Commission voted in mid February to allow grid managers to compensate energy storage the same as traditional power generators. Energy storage would thus graduate beyond the injection of electrons to prevent lights from flickering out and into the wholesale energy markets. Storage devices can also start up in seconds while generators take much longer.

Four: Renewable energy continues to be a bright spot on the energy horizon. Bloomberg New Energy Finance predicts that wind and solar electricity will make up 50% of the world’s energy mix by 2050. That will be a function of the falling price of the underlying technologies as well as $548 billion being invested in storage capacity.
Moreover, wind costs have fallen by 67% since 2009 while utility-scale solar has dropped by 86% since that time, notes financial advisor Lazard. With that, corporations have contracted to buy 7,000 megawatts of renewable energy over four years, which is expected to grow to 60,000 megawatts by 2025, says the Edison Foundation Institute for Electric Innovation.
“Since the 1970s, fossil fuels have commanded a consistent 60-70% share of the global power generation mix. We think this 50-year equilibrium is coming to an end, as cheap renewable energy and batteries fundamentally remake electricity systems around the world,” Bloomberg New Energy Finance’s 2018 report says.

Three: Coal’s continuing saga continues to be bleak. According to Bloomberg New Energy Finance, about 16,200 megawatts of coal generation is expected to retire in 2018, meaning coal will supply less than 30% of the domestic electricity market. Similarly, the Energy Information Administration adds that renewables, excluding hydro, will hit 10% of the U.S. electricity market this year.
Meantime, the Bureau of Labor Statistics says coal jobs are at their lowest level since the mid 1980s: 51,000 nationally. Wind and solar jobs total 474,000, combined, or 100,000 and 374,000, respectively.
But the Trump administration has said that it will try and use the regulatory levers to buttress coal plants that it thinks are vital to the country’s energy security. Its rationale is that such facilities are reliable and keep electricity purring along during harsh weather conditions.
The Federal Energy Regulatory Commission has dismissed that thinking, however, noting that reserve margins are greater than they have ever been and even in areas that rely on coal. In other words, the grid is more dependable than ever, all while wholesale prices are dropping and the level of harmful emissions is going down.
Because coal will still be relied upon not just in this country but also developing countries, it is important that the fuel become cleaner. Coal, in fact, is responsible for a third of all manmade emissions.
To that end, Congress enacted a law this year to give a tax credit of $50 per ton for CO2 that is buried and $35 a ton for CO2 that is re-utilized. With that, Net Power is working with Toshiba Corp. to burn natural gas in oxygen to create pure CO2 — much of which is captured, heated and used to create electricity. The remaining CO2 is captured and either sequestered underground or used to enhance oil recovery. It says that its project is now more viable because of this new law.

Two: The peril of rising temperatures and climate change will loom for decades to come. But the threat level has increased since Trump was sworn in. And 2019 was a marked year.
The UN Intergovernmental Panel on Climate Change report released in October says that keeping temperature increases to 3.6 degrees Fahrenheit by mid Century won’t be enough to avert environmental catastrophes. To make matters worse, at the current pace, such temperature rises could be greater than 7 degrees Fahrenheit. The economic and environmental damages would thus become irreversible.
Meantime, 13 government agencies released the fourth National Climate Assessment six weeks later. Experts there found once more that climate change is primarily human-induced and that global average temperatures are the highest they have ever been.
Importantly, the president has withdrawn from the Paris climate agreement that calls on nations to limit their temperature rises to no more than 3.6 degrees Fahrenheit by mid century, from pre-industrial levels. He is also trying to get out of the Clean Power Plan that would reduce this nation’s CO2 emissions while he has placed tariffs on solar panel imports.
The International Energy Agency said that global CO2 emissions rose, globally,1.4% to 32.5 gigatons in 2017. About two-thirds of the increase is coming from China and India, which are actively addressing air quality issues.
Along those lines, the U.S. Senate confirmed Brett Kavanaugh to the Supreme Court in October. Kavanaugh replaced Justice Anthony Kennedy, who provided the deciding vote to allow the EPA the right to regulate CO2.
Even Kavanaugh has called Obama’s Clean Power Plan that seeks to cut CO2 by 32% by 2030 a “laudable policy.” But he also tamped down his endorsement of the plan during a court hearing by saying, “If Congress does this, they can account for the people who lose their jobs. If we do this, we can’t.”

One: The biggest energy issue to hit this year is not one that has been lingering around but rather, it is one that was brought about solely because Trump is a believer in tariffs, calling himself “a tariff man.”
Economists agree on almost nothing — except that free and fair trade produces better business and healthier economies. And that axiom especially holds true when it comes to the relationship between the United States and China, considering that the Asian nation is the second biggest economy in the world and that it is a voracious consumer of oil and natural gas. In fact, the two economies are inextricably linked to the import-export markets.
In fact, oil and natural gas make up 8% of the gross national product and provide nearly 10 million jobs in the United States, the American Petroleum Institute says. Absent a trade war, by 2020, the United States could be exporting 70 billion cubic meters of LNG and by 2040, the number could be 110 billion cubic meters, says the International Energy Agency in Paris. Chinese gas demand is forecast to grow by 60% between 2017-2023, all of which is tied to China’s domestic policies to reduce local air pollution by switching from coal to gas.
China has become the second largest importer of U.S. crude oil. Until June 2018, it imported 350,000 barrels per day, according to the U.S. Energy Information Administration. That equates to $1 billion of such purchases. But it turned off the spigot in August and September, although it says it will turn it back on.
And, roughly $8 billion worth of utility-scale solar projects — those that connect to the transmission grid — have been killed or delayed, says the Solar Energy Industry Association and Wood Mackenzie Power & Renewables, in a new paper that looks at the impact of solar panel tariffs on imports through 2022. The same analysis says that 9,000 jobs will have been lost or forsaken as a result of the president’s tariffs that were implemented in January.
Trump imposed a 30% tariff on all solar panel imports. It will decline by 5% a year. The tariff is intended to “save” domestic solar makers but American solar companies comprise only 5% of the global production market.

Conclusion: President Obama lifted the country out of recession by, in part, using government’s levers to foster a green energy economy — one that critics said would fail and do little to scrub the environment. President Trump has tried to reverse those same policies, maintaining that his goal has been to level the playing field while creating jobs.
The two philosophies are diametrically opposite. And while Obama’s economy was slow out of the starting gate, it was consistently upward and prolonged. Trump’s economy, by comparison, had an impressive start fueled by corporate tax cuts but two years in, it is sliding back. The takeaway: a low-carbon economy produces economic results. As such, policymakers, globally, should should hasten the transition, not drag their feet.

Melting Arctic Ice Is Now Pouring 14,000 Tons Of Water Per Second Into The Ocean, Scientists Find

Washington PostChris Mooney

A new survey finds that the region has contributed almost an inch to rising seas since 1971.

A new scientific survey has found that the glaciers of the Arctic are the world’s biggest contributors to rising seas, shedding ice at an accelerating rate that now adds well over a millimeter to the level of the ocean every year.
That is considerably more ice melt than Antarctica is contributing, even though the Antarctic contains far more ice. Still, driven by glacier clusters in Alaska, Canada and Russia and the vast ice sheet of Greenland, the fast-warming Arctic is outstripping the entire ice continent to the south — for now.
However, the biggest problem is that both ice regions appear to be accelerating their losses simultaneously — suggesting that we could be in for an even faster rate of sea-level rise in future decades. Seas are rising by about three millimeters each year, according to NASA. That’s mainly driven by the Arctic contribution, the Antarctic and a third major factor — that ocean water naturally expands as it warms.
For Arctic ice loss, “the rate has tripled since 1986,” said Jason Box, first author of the new study and a scientist at the Geological Survey of Denmark and Greenland. “So it clearly shows an acceleration of the sea-level contribution.”
“Antarctica will probably take over at some point in the future, but during the past 47 years of this study, it’s not controversial that the Arctic is the largest contribution of land ice to sea-level rise,” he said.
Scientists in the United States, Chile, Canada, Norway and the Netherlands contributed to the work, published in Environmental Research Letters.
The Arctic is also losing floating sea ice at a rapid pace, but that loss does not contribute substantially to rising seas (though it has many other consequences). Sea ice losses closely match what is happening on land, which makes sense because both phenomena are being driven by the fast warming of the atmosphere in the Arctic, which has heated up at a rate much faster than seen in lower latitudes. Warming seas are also driving some of the ice loss.
Here’s the new study’s tally of where all the Arctic ice loss has come from since 1971:


The research was performed by merging a highly reliable gravity-based measurement of Arctic mass loss from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites with older direct ice measurements, taken from the field, going back to 1971.
The total Arctic loss at present is 447 billion tons of ice per year — which Box calculated is about 14,000 tons of water per second. That’s for the period between 2005 and 2015. Between 1986 and 2005, the loss is calculated at around 5,000 tons per second — therefore, the rate has almost tripled.
Separate research has recently found that the Antarctic’s loss rate has also tripled in just a decade, reaching 219 billion tons per year from 2012 to 2017.
Assuming these numbers are correct and summing them together, the world’s polar regions are losing about 666 billion tons of ice to the ocean each year — amounting to a little bit less than two millimeters of sea-level rise annually.
Treating the Arctic as a whole can miss something, though, notes Christopher Larsen, a glacier expert at the University of Alaska at Fairbanks.
Namely, the Arctic acceleration documented in the study is really being driven by Greenland, which contains more than 20 feet of potential sea-level rise, dwarfing all other Arctic ice sources.
“With respect to the present rate of ice mass loss, and the increasing rates thereof, it is Greenland that has the most significant rate of increased mass loss in the present day,” Larsen said in an email.
“This is especially noteworthy as ultimately Greenland has the most ice to lose in the Northern Hemisphere,” he said. “As rapid as ice loss is now or may become anywhere in the north, the regional totals of ice mass within Alaska or the Arctic Canada are smaller than what Greenland holds.”
To give a sense of the scale of the Arctic losses, Box imagined what it would mean if they were distributed among Earth’s human population.
“If you take the 7.7 billion people on Earth and divide the present-day numbers, from 2005 to 2015, each person on Earth would have the equivalent of 160 liters per day, every day, every year,” Box said.
