The figure in this paper is fascinating. It's the opposite of the famous image of how renewables growth was always under-estimated in energy projections.

Both MethaneSAT and EPA's GHG Inventory had a bad 2025. Comms were lost with the satellite, and Trump is attempting to murder the GHGI. Still, results from the sat are interesting, show Permian Basin emissions 4x larger than EPA estimates www.methanesat.org/project-upda...

Right. People felt policed, but the people doing that policing were also speaking. Harsh counterspeech is also speech. The letter gestures at this but goes on to heavily imply that things would be better if certain unnamed people had not spoken in the way they did. 1/

There's a ton of great stuff in @lioneltrolling.bsky.social 's 'When The Clock Broke' deserving of a fuller review ...but this tidbit about "new class theory" feels particularly relevant to how Trump uses populism to shield (favored) corporate elites from scrutiny.

Nice clear temperature graphic from this NYT article. “Each additional fractional degree of warming brings about a relatively larger increase in atmospheric extremes, like extreme downpours and severe droughts and wildfires,” said @weatherwest.bsky.social

A small thing that struck me in the weird NYT story on trans rights is this "strictest scientific" double standard. I'm not an expert on the literature, but I'd bet this high bar is never ever applied to the TN law or any other anti-trans policies.

Remember when "Google" was synonymous with "learning something new"?

Nationally, Black & Hispanic Americans would experience pollution from LNG terminals at 110–170% rate of white Americans The most impacted areas are already overburdened w other pollution & climate threats Results are consistent w health and EJ concerns that Gulf communities have long voiced 7/x

We estimated cumulative 2023-2050 impacts under different buildout scenarios. The "operating projects only" scenario leads to 2,020 deaths and $28.7 B in health costs. The "full buildout" scenario leads to 4,470 premature deaths and $62.2 B in heath costs. 6/x

To capture the impact of the LNG buildout, we created a database of permitted emissions limits of PM2.5, NOx, SO2 and VOCs for 32 operating, under construction and planned LNG projects. The data was drawn from draft and final air permits. 3/x

*New Report* from #greenpeaceusa and #sierraclub on air pollution from LNG export terminals. Our results suggest this air pollution is already causing scores of premature deaths annually in Texas, Louisiana & regionally. Stopping the LNG buildout would improve health and save lives. 🧵 1/x

The combination of these factors shows that CC can increase local co-pollutant emissions. This is especially concerning during the “mid-transition” – the period when both carbon and non-carbon electrical generation is active. 6/x

Tim Donaghy @timdonaghy.bsky.social · 12/08/2024

Surprisingly, we find that stronger climate targets can lead to more CC generation & can shift some generation from gas to coal. The availability of CC could lead to coal plants running more often & could extend the lifetime of these plants in contrast to other scenarios. 5/x

Tim Donaghy @timdonaghy.bsky.social · 12/08/2024

We consider a 3-node system that can deploy CC on a gas or coal plant, under both a mild and stringent climate target, and a range of installed wind capacity. 4/x

Greenpeace is being sued by a pipeline company for showing solidarity with the 2016-17 #NoDAPL protests. A win for them in court establishes chilling new case law that could make activists and organizations liable for anything done by another protester at the same events. #WeWillNotBeSilenced

The president of COP 28 just claimed that there is “no science” behind the need to phase out fossil fuels in order to limit global warming to 1.5˚C. It all makes sense when you remember he heads up an oil company. www.theguardian.com/environment/...
