Coalition quietly adds fossil fuel industry leaders to emissions reduction panel (excerpts): The Guardian


"The Morrison government has quietly appointed fossil fuel industry leaders and a controversial economist to a committee responsible for ensuring the integrity of projects that get climate funding.

Critics have raised concerns about whether some appointees to the Emissions Reduction Assurance Committee may have a potential conflict of interest that could leave its decisions open to legal challenge.

The overhaul of the committee follows the government indicating it plans to expand the industries that can access its $2.5bn emissions reduction fund, including opening it to carbon capture and storage (CCS) projects by oil and gas companies."

........

 "Bill Hare, the chief executive and senior scientist with Climate Analytics, said it appeared the government had appointed “mostly people concerned with the status quo” rather than aiming for a rapid shift towards zero emissions.

He said he was concerned the government planned to allow fossil fuel companies to receive climate funding for merely reducing emissions below inflated estimates of what their CO2 output otherwise might be."

............

"The emissions reduction fund has so far operated with limited success in reducing national emissions. The government has paid $740m for emissions cuts and signed contracts for another $1.66bn. Despite this, national emissions had dipped only slightly since the Coalition was elected in 2013 prior to the Covid-19 shutdown.

Government data shows the small reduction was overwhelmingly due to the rise of solar and wind energy, which are not supported through the fund."

How the world’s biggest emitter could be carbon neutral by 2050 (excerpts): Vox

 "China’s road to net-zero emissions

The new study contains many significant recommendations; key among them is the timeline for China’s decarbonization.

When Xi Jinping announced the goal of carbon neutrality by 2060, it was broadly interpreted to refer to carbon dioxide, the main gas driving global warming, and not other greenhouse gases, like methane or nitrous oxide. But the researchers suggest otherwise, saying China should reach net-zero for all greenhouse gases by 2060, and net-zero for carbon dioxide by 2050.

In his presentation of the results on Monday, He Jiankun, a Tsinghua professor and climate expert who co-led the study, said his understanding is that Xi’s goal of “carbon neutrality” by 2060 was referring to all greenhouse gases. An expert source told China Dialogue that this interpretation shouldn’t be understood as the official government stance until it is further clarified. But if official, it would mean China would have to cut emissions more rapidly over the coming decades.

The research also shows what net-zero emissions might look like for the world’s top emitter. Under their net-zero emissions scenario, the researchers propose almost entirely replacing fossil fuels with clean energy in the electricity sector, leaving coal power at less than 5 percent of power generation — a massive drop from the almost 70 percent coal supplied in 2019." .....

.................

.... "What to watch for in the coming year

Although this new study has strong backing from people with connections to the highest levels of government, its place in China’s official plans will be clearer when China submits its “mid-century strategy,” a document that all signatories of the Paris Agreement are requested to complete by the end of 2020 to chart out long-term decarbonization. (China is expected to release this document sometime in the next few months.)

As for more immediate decision-making, the study authors also recommend that China upgrade its climate and energy targets under the Paris Agreement and in its five-year plan. China’s carbon emissions are still growing — last year saw a 2 percent increase — so the authors advise that the next five-year plan set a hard cap on carbon emissions at 10.5 billion tons. As for setting new Paris Agreement targets this year, one key recommendation is to up the 2030 target from 20 percent non-fossil fuel energy generation to 25 percent to speed China’s renewable energy build-out.

Whether China adopts these upgraded targets in the coming months will be a first real indication of how and when the country plans to get to net zero."

Young people’s burden: requirement of negative CO2 emissions: Hansen et al

Abstract. 

The rapidity of ice sheet and sea level response to global temperature is difficult to predict
Melting ice sheets
Global temperature is a fundamental climate metric highly correlated with sea level, which implies that keeping shorelines near their present location requires keeping global temperature within or close to its preindustrial Holocene range. 

However, global temperature excluding short-term variability now exceeds +1C relative to the 1880–1920 mean and annual 2016 global temperature was almost +1.3C. 

We show that global temperature has risen well out of the Holocene range and Earth is now as warm as it was during the prior (Eemian) interglacial period, when sea level reached 6–9 m higher than today. 

Further, Earth is out of energy balance with present atmospheric composition, implying that more warming is in the pipeline, and we show that the growth rate of greenhouse gas climate forcing has accelerated markedly in the past decade.  

The rapidity of ice sheet and sea level response to global temperature is difficult to predict, but is dependent on the magnitude of warming. 

Targets for limiting global warming thus, at minimum, should aim to avoid leaving global temperature at Eemian or higher levels for centuries. 

Such targets now require “negative emissions”, i.e., extraction of CO2from the air. 

If phase down of fossil fuel emissions begins soon, improved agricultural and forestry practices,including reforestation and steps to improve soil fertility and increase its carbon content, may provide much of the necessary CO2 extraction. 

In that case, the magnitude and duration of global temperature excursion above the natural range of the current inter glacial (Holocene) could be limited and irreversible climate impacts could be minimized. 

In contrast, continued high fossil fuel emissions today place a burden on young people to undertake massive technological CO2 extraction if they are to limit climate change and its consequences. 

Proposed methods of extraction such as bio energy with carbon capture and storage (BECCS) or air capture of CO2 have minimal estimated costs of USD 89–535 trillion this century and also have large risks and uncertain feasibility.    

Continued high fossil fuel emissions unarguably sentences young people to either a massive, implausible cleanup or growing deleterious climate impacts or both.

Stanford Study Says Renewable Power Eliminates Argument for Using Carbon Capture with Fossil Fuels: DESMOG

New research from Stanford University professor Mark Z. Jacobson questions the climate and health benefits of carbon capture technology against simply switching to renewable energy sources like wind and solar. Carbon capture technology is premised on two possible approaches to reducing climate pollution: removing carbon dioxide from the atmosphere anywhere in the world, an approach generally known as direct air capture, or removing it directly from the emissions source, such as the smoke stack of a fossil fuel power plant.

How to erase 100 years of carbon emissions? Plant trees—lots of them.

Increasing the Earth’s forests by an area the size of the United States would cut atmospheric carbon dioxide 25 percent.

 PUBLISHED


An area the size of the United States could be restored as forests with the potential of erasing nearly 100 years of carbon emissions, according to the first ever study to determine how many trees the Earth could support.
Published today in Science, "The global tree restoration potential” report found that there is enough suitable land to increase the world’s forest cover by one-third without affecting existing cities or agriculture. However, the amount of suitable land area diminishes as global temperatures rise. Even if global warming is limited to 1.5 degrees Celsius, the area available for forest restoration could be reduced by a fifth by 2050 because it would be too warm for some tropical forests.
“Our study shows clearly that forest restoration is the best climate change solution available today,” said Tom Crowther, a researcher at ETH Zürich, and senior author of the study.

Restoring forests may be one of our most powerful weapons in fighting climate change: Vox



Preserve Forests
One of the technologies for tackling climate change I’m most excited about is direct air capture: using huge electric-powered scrubbing machines to filter carbon dioxide directly out of the air and either stashing it deep underground, or using it for industrial purposes.
 
Adding 2.2 billion acres of tree cover would capture two-thirds of man-made carbon emissions, a new study found.



Allowing the earth’s forests to recover could soak up a significant amount of humanity’s greenhouse gas emissions, according to new research. 

The worldwide assessment of current and potential forestation using satellite imagery appeared Thursday in the journal Science. It estimates that letting saplings regrow on land where forests have been cleared would increase global forested area by one-third and remove 205 billion metric tons of carbon from the atmosphere. That’s two-thirds of the roughly 300 billion metric tons of carbon humans have put up there since the dawn of the Industrial Revolution. 

“The point is that [reforestation is] so much more vastly powerful than anyone ever expected,” said Thomas Crowther, a professor of environmental systems science at ETH Zurich and a co-author of the paper. “By far, it’s the top climate change solution in terms of carbon storage potential.”


Some climate scientists who were not involved with the study disagree with its calculations and are warning against its “silver bullet” message. Still, supporting natural systems that can soak up carbon is widely accepted as a major component of any climate change mitigation strategy — in addition to deploying clean energy, switching to electric vehicles, and curbing consumption overall.

The heat is on over the climate crisis. Only radical measures will work : The Guardian

Experts agree that global heating of 4C by 2100 is a real possibility. The effects of such a rise will be extreme and require a drastic shift in the way we live


Drowned cities; stagnant seas; intolerable heatwaves; entire nations uninhabitable… and more than 11 billion humans. A four-degree-warmer world is the stuff of nightmares and yet that’s where we’re heading in just decades.


While governments mull various carbon targets aimed at keeping human-induced global heating within safe levels – including new ambitions to reach net-zero emissions by 2050 – it’s worth looking ahead pragmatically at what happens if we fail. After all, many scientists think it’s highly unlikely that we will stay below 2C (above pre-industrial levels) by the end of the century, let alone 1.5C. Most countries are not making anywhere near enough progress to meet these internationally agreed targets.

DESMOG: Renewables Offset 35 Times More CO2 Every Year Than All Carbon Capture Projects Ever, New Analysis Finds




By Justin Mikulka (6 min. read)
A new analysis by Clean Technica found that global investment in carbon capture and storage technology (CCS) adds up to roughly $7.5 billion total. It also examined how much, for that investment, CCS has reduced atmospheric carbon dioxide (CO2) levels compared to an equivalent investment in renewable power generation.

The analysis calculated that “wind and solar are displacing roughly 35 times as much CO2 every year as the complete global history of CCS.” Clean Technica's Mike Barnard concluded, “CCS is a rounding error in global warming mitigation.”

The (Australian) government thinks we’re idiots and is not serious about reducing emissions : The Guardian

"Tackling climate change is tough and Scott Morrison’s latest policy is an insult"

"This fund of $2bn over 10 years is not just a rebranding of Tony Abbot’s Direct Action, it is actually a diminishment of it. At $200m a year on average it is less than half the money a year that was spent on Direct Action – a policy that was so laughably bad that a government with any level of shame would quietly have dumped it and pretended it never happened.

Yet, here we are. Nine years after Lenore Taylor ripped apart

the Liberal party’s policy of reliance on “soil magic”, we have the prime minister still thinking such measures of carbon sequestration are worth pursuing and will achieve anything close to what is required."

Climate Change: The Antidote To Democracy’s Mid-life Crisis: Medium

 
Graph showing Opinion on climate change
Opinion on climate change

"The manifesto for this new democratic movement will contain few, if any, new ideas. Rather, it will organise a familiar set of policies into a coherent programme:


A flat-rate, no-exceptions tax on emissions — possibly linked to a dividend for all citizens, or with revenues used to fund other climate protection measures.
  1. Investment in renewables and low-emission transport infrastructure, which will also create jobs.
  2.  
    Enhanced protections for natural carbon sinks in public hands, and incentives for private landowners to increase the quantity of carbon stored by the trees, plants and soils on their land.
  3.  
    Funding for research into carbon capture and use, energy storage and next generation renewables.
  4.  
    Higher mandatory energy efficiency standards for all new buildings, saving households and businesses money on their energy bills.
  5.  
    Scrappage schemes for petrol and diesel vehicles and money for homeowners and landlords to upgrade the energy efficiency of existing properties.
  6.  
    Investment in climate adaptation and resilience to ensure those most exposed to the impacts of extreme weather — from hurricanes to forest fires — are as well protected as possible.
  7.  
    Public awareness campaigns to promote dietary changes that both reduce emissions and improve health.
  8.  
    Lowering the voting age to 16, as a way of giving greater democratic voice to those who will be most personally affected by the long-term consequences of global warming."
