“SHORTCOMINGS OF IPCC AR6 WGIII MITIGATION REPORT
The report has severe shortcomings, including:
The IPCC makes it look as if the temperature rise could be restricted to 1.5°C above pre-industrial and insists there was a carbon budget left, to be divided by using monetary analysis.
This narrative results in a failure to highlight in the SPM some key drivers of change (such as heat pumps in buildings and air taxis in transport) and in inappropriately referring to such key drivers of change as 'options', while failing to mention the best policies to achieve the necessary changes, i.e. through local feebates.
The second image, from the report's SPM, shows options by sector with the length of each bar indicating their potential for emissions reduction by 2030, while the color inside the bar gives a cost estimate.
These are not genuinely options, since the dire situation leaves little choice and instead makes it imperative to act most urgently, comprehensively and effectively on climate change, in line with the Paris Agreement.
The Paris Agreement does instruct the IPCC to describe the best pathways to achieve this and the IPCC has until now refused to do so. As Arctic-news blog has pointed out for more than a decade, mitigation is most effectively achieved by offering people a range of options, preferably through local feebates, which will also make such policies more popular.
Options are more appropriately included in feebates, as they can offer a range of options, with the more polluting options attracting fees and with the revenues used to fund rebates on the cleaner options.
An example of a wider set of local feebates is depicted in a 2019 analysis of EV policy. A more diverse set of feebates could include not only fees on fuel and fuel-powered vehicles, but also on facilities that sell or process fuel, vehicle registration, parking, toll roads, etc.
It's important to act comprehensively, along several lines of action, e.g. to redesign cities and plan for air taxis.
Given the urgency to act, such lines of action are all best implemented as soon as possible, yet at the same time many lines of action are best kept separate.
It makes a huge difference whether to use a Gobal Warming Potential (GWP) for methane of 171 over a few years, or to use - as the IPCC does - a GWP of 28 over 100 years.
Fees on sales of livestock products can raise revenue for pyrolysis of biowaste, with the resulting biochar added to the soil. That would also support the transition toward a vegan-organic diet more strongly, in line with the conclusion of an earlier IPCC report that a vegan diet ranks highest regarding mitigation.
The Climate Plan prefers local feebates. Where necessary, fees can be set high enough to effectively ban specific alternatives.
Furthermore, instead of using money, local councils could add extra fees to rates for land where soil carbon falls, while using all the revenues for rebates on rates for land where soil carbon rises.
That way, biochar effectively becomes a tool to lower rates, while it will also help improve the soil's fertility, its ability to retain water and to support more vegetation. That way, real assets are built.

“IPCC KEEPS FEEDING THE ADDICTION
The IPCC just released its report Global Warming of 1.5ºC. Things aren't looking good and instead of providing good advice and guidance, the IPCC bends over backward in efforts to keep feeding the addiction.
The Paris Agreement constitutes a joint commitment by all nations of the world to keep the temperature rise below 1.5ºC. The IPCC should have honored this commitment by explaining that the situation is dire and by pointing at action to be taken to improve the situation.
Instead, the IPCC bends over backward to make it look as if temperatures were lower than they really are, in an effort to make it look as if there were carbon budgets to be divided, and polluters should be allowed to keep polluting until those budgets had run out. This is like saying that drug junkies who cause damage and are deeply in debt, should be handed over more OPM (other people's money, in this case the future of all people and other species).
In reality, there is no carbon budget to be divided, there is just a huge carbon debt to be repaid. The urgency and imperative to act is such that progress in one area cannot make up for delays elsewhere. The best policies should be implemented immediately, and everywhere across the world.
Use of terms such as trade-offs, net-outcomes, off-sets, carbon budgets and negative emissions is misguided and highly misleading. Policies based on giving and trading in permits to pollute are less effective than local feebates, i.e. polices that impose fees on sales of polluting products and then use the revenues to support rebates on the better alternatives sold locally.
Twelve instances where the IPCC is misleading are described at the post 'IPCC keeps feeding the addiction', at:”

“Can't Be Bothered: Are We All Climate Deniers?”
“[This is not your usual climate change event]
Most of the talks surrounding climate change involve discussions of facts, causalities, responsibilities and climate actions.
.
However, like many other scientific topics, from evolution and vaccination to the reality of the pandemic, discussions like these often ignore the other side of scientific arguments, a.k.a the voice of the dissenters or deniers.
.
Deniers are more common than we think. In fact, both you and me are likely a denier in some way or another. Even if you accept scientific facts, you can still be a denier. 👁
.
Unlike most ongoing discussions on climate change, we will take a deep dive into the topic of denial. We will:
• Dissect the logic and reasoning behind deniers ,
• Guide you to revisit your own cognitive system for signs of denialism ,
• Trace the root of denial to free-market capitalism and neoliberalism , and
• Show how denial can result in difficult ethical dilemmas and decision-making in everyday life
Well, are you a denier? You can only find out by joining this event.

“Large-scale deployment of carbon dioxide removal (CDR) methods is now "unavoidable" if the world is to reach net-zero greenhouse gas emissions, according to this week's report by the Intergovernmental Panel on Climate Change (IPCC).
The report, released on Monday, finds that in addition to rapid and deep reductions in greenhouse emissions, CO₂ removal is "an essential element of scenarios that limit warming to 1.5℃ or likely below 2℃ by 2100."
CDR refers to a suite of activities that lower the concentration of CO₂ in the atmosphere. This is done by removing CO₂ molecules and storing the carbon in plants, trees, soil, geological reservoirs, ocean reservoirs or products derived from CO₂.
As the IPCC notes, each mechanism is complex, and has advantages and pitfalls. Much work is needed to ensure CDR projects are rolled out responsibly.”

“NASA's GEDI mission has reached a major milestone with the release of its newest data product, which provides the first near-global estimate of aboveground forest biomass and the carbon it stores—filling a key gap in climate research.
The data enables research into how Earth's forests are changing, what role they play in mitigating climate change, and the regional and global impacts of planting and cutting down trees.
With the new data product from GEDI, the Global Ecosystem Dynamics Investigation, ecosystem and climate researchers can quickly locate their regions of interest and study forest structure and carbon content with greater precision than in the past.
The new biomass product release comes as GEDI is within a one-year mission extension and represents the culmination of critical advancements in spaceborne lidar (a type of laser) research.”
