Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The justices have spent the last few years invalidating environmental protections and handcuffing federal regulators. There’s more in store this term.

Helene was the second major hurricane (Cat 3 or higher) of the 2024 season. Record-setting Hurricane Beryl preceded it as the earliest-forming Category 5 hurricane in the Atlantic basin’s history. Beryl became a major hurricane in the month of June east of the Lesser Antilles, the first time that’s ever happened during the first month of hurricane season since record-keeping began in 1851.

While Beryl weakened before reaching the United States as a Category 1 hurricane, Helene intensified into a major hurricane and continued strengthening right up to landfall. That now puts 2020-2024 into the record books, tying the mark for the longest consecutive number of years (five) in which a major hurricane has made landfall in the United States.

For decades, I had felt in control. Not in control of the weather, of course. But in control of the message that, if my audience was prepared and well informed, I could confidently guide them through any weather threat, and we’d all make it through safely. Today as a result of so many compounding climate-driven factors, the warming world has forcibly shifted my manner from calm concern to agitated dismay.

Maybe EVs are not a comprehensive climate solution??

Reporting Highlights

Intense Debate Over Solar: A large solar farm proposed in Knox County, Ohio, has drawn about 4,000 public comments — more than any other solar project in the state.
Newspaper Misinformation: After the local paper was sold to Metric Media, part of a “pink slime” network, the Mount Vernon News published one-sided coverage and dubious claims about solar power.
Fossil Fuel Influence: Opposition to solar was stoked by a group whose major donor — a retired gas-industry executive — also leads a pro-gas dark-money organization.

These highlights were written by the reporters and editors who worked on this story.

The Manufacturer's Accountability Project is ubiquitous fighting cities' and states' suits against oil companies. Now, it's clear they're being funded directly by at least one of those companies.

It hit catagory 5 in less than 24 hours. Obviously, storms like this are getting worse as the climate gets hotter but I was wondering just how uncommon this expediency is?

I'll note that their definition of harms includes a lot of things besides just greenhouse gas emissions and climate impact. Full paper here

Basically makes the case that as a society, we're better off with smaller cars.

China should set a "strong but achievable" target of slashing emissions at least 30 percent by 2035 when it submits updated climate commitments in coming months, a report urged Thursday.

Signatories to the 2015 Paris climate accord must announce by next February their updated roadmaps to achieve the treaty's goal of limiting global temperature rises.

China currently aims to peak carbon dioxide emissions before 2030 and reach carbon neutrality by 2060.

But its policies and targets are rated "highly insufficient" to limit global warming to 1.5 Celcius above pre-industrial levels, according to the Climate Action Tracker project.

The Centre for Research on Energy and Clean Air (CREA), a think tank that tracks climate progress, said Beijing should aim for an absolute emissions reduction target of 30 percent.

As the world's largest emitter, China's "ambition in its climate agenda is decisive for keeping the international community on track," CREA said in a report.

To meet that target, Beijing would need to slash electricity sector emissions by 30 percent and emissions from industry by a quarter. It should also set a target of reducing non-CO2 emissions by more than 35 percent, the group said.

[...]

But Teng Fei, deputy director of Tsinghua University's Institute of Energy, Environment and Economy, called the "extreme" goal of a 30 percent emissions cut "too ambitious to be achievable".

"I think China is in the process of stabilising its emissions, so it's quite uncertain, for this period, to what extent China can reduce its overall emissions," he said.

China is currently moving to bolster its flagging housing market, which could trigger higher demand in industry, and increase emissions.

[...]

Coal installation is continuing [in China] in a bid to secure baseload supply, and methane emissions are also rising.

They're pretty transparently using this to get funding for what are basically run as PR moves, rather than a serious attempt to limit greenhouse gas emissions — that entails leaving more than half the proved reserves of oil in the ground.
