Alan Kohler writes twice a week for The New Daily. He is also editor in chief of Eureka Report and finance presenter on ABC News.
The only worthwhile 2030 political emissions reduction target is the Greens’ 75 per cent, which is more or less impossible.

So the main task of government from here should be to prepare the country for the effects of global warming.

Doing something to try to prevent it is important, but secondary.

In 2009, the then Department of Climate Change prepared a “first pass” assessment of the risks to Australia’s coasts, which was the only thing the government has ever produced about climate change risks.

It needs to be updated and extended to all risks, so we all know what we’re going to be in for.

Whenever the Greens’ target is mentioned, it’s dismissed as “extreme” and “radical”, and when lined up against the LNP’s 26 to 28 per cent, Labor’s 43 per cent and everybody else’s 50 per cent, it does look to be both of those things.

The trouble is that these political targets have nothing to do with science, and it’s clear that politics – both democratic and autocratic – is incapable of dealing effectively with climate change.

As Labor climate change spokesman Chris Bowen put it at the National Press Club: “Our target of 43 per cent emissions reductions over the years to 2030 is ambitious and achievable.”

By which he means it looks relatively ambitious and is politically achievable. Why 43? Because it sounds better than 26 to 28, a bit less ambitious than their previous 45, and more achievable than 50 or, God forbid, 75.

The problem with all of these numbers is that greenhouse gases, both carbon dioxide and methane, stay in the atmosphere, so the best way to look at emissions is cumulative, not year by year, since they accumulate.

Our carbon budget

The annual emissions targets everybody is arguing about are just a way of achieving a cumulative number that might be consistent with preserving our way of life.

So far, 1.6 trillion tonnes of carbon dioxide have been put into the atmosphere since 1751, which has warmed the planet by an average of about 1 degree centigrade above the average temperature of 1850 to 1900. It’s all still there.

The Intergovernmental Panel on Climate Change (IPCC) has produced a range of possible budgets to keep further warming to 1.5 and 2 degrees from here.

For a 50 per cent chance of 2 degrees, it’s 1350 gigatonnes (billion tonnes) of carbon dioxide; for 67 per cent it’s 1150 GtCO2; and for 83 per cent it’s 900 GtCO2.

For a 50 per cent chance of 1.5 degrees, it’s 500GtCO2; for 67 per cent it’s 400; and for an 83 per cent chance it’s 300.

It’s a wide range with a variety of probabilities for us to choose from, but to keep it simple for policymakers they came up with a “net zero by 2050” target to aim at after the Paris meeting in 2015, in line with the 67 per cent probability of 2 degrees of warming.

By the way, an outfit called the Mercator Research Institute on Global Commons and Climate Change has a fairly frightening clock ticking down for both 2 degrees and 1.5 degrees, showing 1071 and 321 GtCO2 to go, respectively.

Catastrophic warming

In Glasgow this year, the thinking shifted from 2 degrees to 1.5 degrees because it’s felt that 2 degrees would still be catastrophic.

The current 1 degree of warming is bad enough, and the frequency of extreme weather is not a linear progression with the increase in temperature: The difference between 1 and 1.5 degrees is greater than 50 per cent.

The general 2050 net-zero target was unchanged in Glasgow, but the focus shifted to 2030 so that the task in the next 20 years wouldn’t be too great.

So everybody agreed to come back next year with a more ambitious target for 2030; the Australia government signed that, but then said it wouldn’t deliver a higher target.

It’s also likely that the focus will now shift to carbon budgets rather than annual emissions.

The last official government estimate of Australia’s share of the global budget was published by the Climate Change Authority (CCA) in 2014 – before the Clean Energy Act was repealed in July that year and any further calculations were shut down (while keeping the CCA barely alive).

According to the CCA then, Australia’s carbon emissions budget for 2 degrees of warming for the period 2013 to 2050 was 10.1 million tonnes. It’s probably a bit more now.

The way we’re going, it will be spent by 2033, not 2050.

This year a group called the Climate Targets Panel, brought together by former Liberal Party leader John Hewson, updated Australia’s budget for 1.5 degrees of warming, from 2021.

It’s 3.5 billion tonnes, and will be spent by 2028 at the current rate of 498.9 million tonnes per year (reported by the Department of Industry’s in its latest National Greenhouse Gas Inventory for June 2021).

To keep global warming to 1.5 degrees, and therefore a budget of 3.5 million tonnes, Australia’s emissions would have to be cut by about 75 per cent by 2030, or to 125 million tonnes, which is the reason for the Greens’ target.

But is that even possible?

Basically, it would require all coal-fired electricity generation to be shut down over the next two or three years and replaced with solar, wind and batteries and most transport and household heating and cooking to switch to electricity, away from gas, very quickly indeed.

It may be theoretically possible, but would cost the government a multiple of Labor’s $24 billion Powering Australia plan for a 43 per cent emissions reduction by 2030.

That means the real problem for Australia in combating climate change is that the budget deficit to be revealed next week is about $100 billion and government debt is more than $850 billion because of the pandemic.

When politics fails

The spending and sacrifice required for 1.5 degrees is politically impossible, and 2 degrees is close to impossible.

Something similar applies globally.

Governments everywhere are mired in debt while pledging to cut emissions to net zero by between 2030 and 2060, mostly 2050.

Some, like Europe, are using emissions trading schemes to force the private sector to pay for it, while others, like Australia, are planning to use taxpayers’ money.

But the average global carbon price of about $4.50 per tonne is way too low to have any serious impact, and most government spending proposals are hopelessly inadequate for the simple reason that the pandemic has emptied the coffers (unless governments around the world have an unlikely conversion to Modern Monetary Theory).

Ross Garnaut devoted a chapter of his 2008 Climate Change Review to adaptation, starting with these words: “Mitigation will come too late to avoid substantial damage from climate change.

“Some may expect that government can, and should, protect the community from climate change by implementing the right strategy, program or initiative to allow Australians to maintain established lifestyles. This is not a realistic expectation …”

I remember thinking at the time that this was a big statement.

Since then, there has been nothing from government about what to expect, apart from that “first pass” on the coastal impact from the Department of Climate Change and endless optimism about how we’re meeting and beating our targets and everything will therefore be OK.

As Garnaut wrote 13 years ago: This is not a realistic expectation.

(Kenya CBC) Domino Effect

CBC News - Margaret Evans

Climate change is tilting the balance of nature for Kenya’s Lake Nakuru, setting off a whole house of cards in a place that once had a reputation of unparalleled beauty.

There is a strange new world taking shape in a community called Mwariki on the shores of Lake Nakuru, just a few hours’ drive north of the Kenyan capital of Nairobi.

Shirtless young men can be glimpsed through a forest of dead trees, wading through chest-deep water with fishing nets trailing behind them.

Squadrons of pelicans float along what used to be streets in a slow-motion display of synchronized swimming, dipping their heads under water as one to scoop up dinner in their pouches.

And cormorants perch on the walls of gutted houses half underwater.

Lake Nakuru is one of a string of lakes in the Great Rift Valley where climate change is blamed for unprecedented rainfall over the past decade and flooding that has displaced thousands.

“When I came here I was very happy,” 51-year-old Jane Wanjiru said as she was seated in the front of a boat taking us from the new shoreline to the home she lost to rising water in the spring of 2020.

“Because it was mine,” she said. “I opened my own gate. My children were playing in my own compound.

“We thought [then] after six months or three months the water will go back.”

But it stayed, sinking her dreams.

For Wanjiru, a single mother, the house represented her climb out of a slum in nearby Nakuru Town and the single room she shared there with her two daughters.

She was able to afford it by joining a savings group supported by an NGO called Muungano wa Wanavijiji (Federation of Slum Dwellers). It helps make loans more accessible to the urban poor.

Wanjiru is devastated by what’s happened.

“When you come from very low and then you get something that you feel you are proud of it, and then a disaster like this comes, you feel very bad. Very bad.”

Especially when there’s little, if any, hope of compensation in sight. If government money does arrive, it will likely go toward repairing infrastructure such as downed power lines and a sewage treatment plant also under water.

In the same part of Mwariki, 173 households lost their properties, most like Wanjiru having saved for years, pooling their resources in order to buy a plot of land they would divide between them.

“We are facing a lot of problems,” Joseph Oyawa, assistant chief for the area affected by the flooding, said as he was sitting in a small hut with a tin roof and rain pounding down on it.

“We don’t have houses for them to stay. It’s a problem of housing,” he said. “Most of them were not employed. They were just casual labourers.”

The influx of young men from other parts of Kenya who are looking for a livelihood and hoping to fish has brought its own set of social problems, he said, adding to housing problems.

Oyawa remembers the days when Lake Nakuru almost ran dry in the early 1970s.


Locals say over the past decade, it’s grown from about 40 square kilometres to 70. And it’s not just humans suffering.

“The [wildlife] reserve to the south, they’re complaining there’s not space enough for the habitat of the animals there because of the swelling of the lake,” said Oyawa.

The top of an electric fence that once kept lions and hippos and rhinos away from the community can be seen peeking above the water opposite Wanjiru’s submerged house.

Lake Nakuru National Park, recognized as a UNESCO world heritage site in 2011 for its biodiversity, used to encompass the entire lake. But it’s now expanded beyond the park’s borders.

It’s one reason so many young men feel emboldened to try their hand at fishing. The lines about where legal fishing is allowed have blurred. In the past, the Kenyan Wildlife Service limited it within the park.

“Those youth have absolutely zero source of livelihood,” said local ecologist Jackson Raini. Three new species of fish have appeared in the lake in recent years, one theory being that they’d been swept in from nearby pond fisheries.

“But some studies we’ve conducted indicate that the fish have a fairly elevated concentration of heavy metals especially chromium and lead, which are above the World Health Organization standards,” he said.

The high levels of metal used in tannery industries in Nakuru Town find their way to the lake even when treated properly, according to Raini.

And hippos and flamingos have been drawn to the damaged sewage treatment plant, and so closer to human settlements, by algae growing in the sewer line.

Raini said what’s happening in and around Lake Nakuru is an example of the kind of chain reaction climate change can set off.

Why don’t the flamingos come to Lake Nakuru the way they used to? 1min

He started working at the lake in the early 1990s and stayed because of all it had to offer. It is recognized by an international treaty signed in the 1970s as a wetland of international importance.

“Just bursting [with] life. Millions of flamingos, you know, flying. Pelicans, cormorants, the kind of variety that was simply inspiring,” said Raini.

But the flooding has changed the ecology of the lake, with runoff and rains diluting its salinity and affecting the algae flamingos like to feed on.

“This algae disappeared almost completely,” he said. “And that really interfered with the basic food chain. So the flamingos have reduced in numbers from the millions that we used to see earlier to now where you just see a few hundred.”

Massive deforestation caused by industry upstream has contributed, he said, and a shifting of the tectonic plates in the Rift Valley is thought to be possibly impacting groundwater levels.

But like many scientists, Raini said climate change is the amplifier, changing destinies.

The Nakuru Lake National Park is the second most important in terms of tourism dollars in Kenya, but it’s also having to adapt to a new reality.

Safari roads around the lake have been washed out and available habitat for wild animals like lions, baboons, giraffes and rhinos has shrunk.

Raini said projections suggest that the next 10 years in this part of Kenya are set to get even wetter.

“We have seen that the groundwater levels have risen by eight to 10 metres. So that means that the catchment area is super saturated, that any more additional water we get from the effects of climate change is not likely to percolate. It’s actually likely to spread further and cause more damage, especially at local communities.”

Extreme weather events are already displacing around 20 million people a year, according to the United Nations, more than those being displaced by violence or conflict.

Help responding and adapting to the changing climate has been one of the main demands from developing countries including Kenya at successive UN climate conferences like the one in Glasgow in November.

The connection is not lost on those in Mwariki still hoping someone somewhere might care about what they’ve lost.

“This thing is happening all across the world,” said David Kahoro Kiragu, a local elder who lost his small subsistence farm in the flooding last year.

“But we are blaming people because they have interfered with the environment, especially even the other [Western or developed] countries because of industries and all of this.”

Sixty-year-old Kiragu and his family were initially housed by a church in a classroom. But when school started, they had to move and they’re now accepting charity from a friend of the family.

“We are actually internally displaced and we are suffering in one way or another,” said Kiragu.

Both Kiragu and Wanjiru say they’ve been ignored by their own government at the county and federal levels, and both say they feel too old to start over again in such harsh conditions.

“No one talks to us,” said Wanjiru. “Now we have become hopeless.”

'We are blaming people because they have interfered with the environment,' says local elder David Kahoro Kiragu, front, referring in particular to developed countries and industry. (Margaret Evans/CBC)

One local official at Nakuru County’s government offices in Nakuru Town said they would like the national government to buy the flooded properties to compensate those who’ve lost everything and then to hand that land over to the Lake Nakuru National Park.

But there is no suggestion that is likely to happen any time soon.

“There’s a challenge because there’s no money,” assistant chief Oyawa said, sitting in his small hut. “So the government must sit down so that they can get that money to buy that.” But he, too, is looking to the outside world and the countries making promises about helping poorer countries already being buffeted by climate change.

“They need to be told that there are some people on the ground suffering.”

(AU The Conversation) The End Of Coal Is Coming 3 Times Faster Than Expected. Governments Must Accept It And Urgently Support A ‘Just Transition’

Coal is likely to be completely gone from Victoria’s electricity system by 2032 with most other parts of Australia not far behind, a report from the Australian Energy Market Operator (AEMO) declared last week.

The report, called the 2022 Integrated System Plan, confirmed what many of us in energy policy have long known: the end of coal is coming, and the pace may take some industries and governments by surprise.

The Integrated System Plan (ISP) is effectively the planning “blueprint” the market operator publishes to help industry and policy makers assess how Australia’s electricity system might evolve. It’s an incredibly important document for guiding where and when investment is needed to unlock new renewable resources to meet demand.

Given ISP’s prediction for the rapid closure of coal-fired power stations, it’s critical governments don’t stick their heads in the sand. Continuing to deny the impending end of coal-fired generation is simply not in the interest of coal workers and their communities, who urgently need support.

What is AEMO predicting?

The most important aspect of the ISP is that what used to be called the “step change” has now become the “central scenario”. For the first time, this central scenario is consistent with Australia’s commitment under the Paris Agreement and limiting global temperature rise to under 2℃.

The ISP is forecasting that huge volumes of coal will be retired in the next ten years, including all brown coal and two-thirds of black coal, and significant investments in new renewables and “firming technologies” (such as batteries, gas, and pumped hydro) will take their place.

‘Firming’ technologies like pumped hydro are critical to ensure Australians have electricity when wind and solar aren’t available. Shutterstock

Around 14 gigawatts (GW) of coal is now assumed to be exiting the National Electricity Market this decade – more than three times the amount of coal retirements the industry has announced.

Effectively, AEMO is saying (yet again) that the incumbent industry is likely to be caught by surprise by the speed of the transition.

It’s not just an explosion of renewables investment that AEMO predicts. Around 9GW of gas-fired generation and an extra 620GW hours of storage (provided by batteries or pumped hydro) will be required to provide backup generation capacity when solar and wind are unavailable.

Electricity demand is expected to surge out to 2050 and will double to at least 350 terrawatt hours. This includes from electric vehicles uptake, converting natural gas heating and hot water to electric in homes, and electrifying many industrial processes such as low-emissions steel and aluminium.

All these developments will require a major overhaul of the grid. The ISP states around A$12.5 billion in transmission spending needs to occur to unlock $29 billion in investment benefits.

Why is coal being left behind?

There are two main drivers for this significant substitution of coal for new technologies.

First, the cost of these technologies continues to fall rapidly and consumers are voting with their feet. Some of Australia’s largest and most iconic businesses are increasingly buying 100% of their energy from renewable resources, including Woolworths, BHP and Coles.

Second, state governments have filled the void left by the lack of a nationally consistent energy and climate policy, and are now implementing ambitious policies to drive the uptake of renewable energy and firming.

The most ambitious of these policies is the NSW government’s 12GW energy roadmap, which effectively prepares for the retirement of ageing coal-fired power stations by facilitating investment in new capacity.

Electricity demand is expected to surge out to 2050. Shutterstock

So what should governments be doing?

It is critical governments focus on a “just transition” to these new technologies, and provide support to communities and workers most impacted, such as those in the Hunter and Latrobe Valleys.

Structural adjustment policies such as job placements, relocation assistance, or financial support to transition local economies are vital to secure opportunities for these regions. Retraining ahead of closures will help workers transition to new or related industries.

Everyone who uses energy must be afforded access to the clean energy transition. At present, the biggest barrier to participating in the solar and battery revolution is owning your own home.

Governments have been absent from this important policy debate. Australian low-income and rental households should be prioritised in any future policies that support adoption of solar and battery storage.

Governments must also ensure the private sector (rather than consumers) wear the risk of poor investments. Governments are increasingly taking on very significant risk (on behalf of consumers) through underwriting renewable energy and firming investments of large multi-national energy businesses.

Some economists (including us) have been providing alternative models for governments to achieve the same objectives, but with greater focus on reducing risks to consumers.

Given the surge in households and businesses voluntarily buying renewable energy, it’s important consumers know what they’re getting. The Clean Energy Regulator is doing some interesting work in this space by developing an emissions and renewable energy transparency register as part of the national greenhouse and energy reporting framework.

If governments really wanted to help, they could introduce a carbon price. Such a policy is considered political poison, but a carbon price would result in us reaching this future in a much less costly and more orderly way.

The end of the coal age

The ISP is forecasting a better and cleaner future. Australia has great opportunities from moving beyond the coal age and into the age of efficient renewable energy, as we’re blessed with some of the best renewable resources on the planet

With global leaders increasingly focused on rapidly reducing emissions, we have a lot to gain through new industries, such as green hydrogen and mineral processing. Both major political parties at the national level have targets that don’t really push beyond what AEMO now thinks is the status quo.

The stone age didn’t end because of a lack of stones. And the coal age is ending despite an abundance of it – whether governments believe it or not.
