The scientific understanding of human-driven climate change is much stronger today than it was in 2009 when the EPA first issued the endangerment finding. There is no scientific basis for the Trump administration's decision to repeal it

A new report by the prestigious US National Academy of Sciences concludes that the EPA’s 2009 endangerment finding was accurate, has stood the test of time, and is now reinforced by even stronger evidence:

Growing connections of AI/DC have now reached a level of complexity warranting a NERC alert, citing "rapid, major swings in load, experienced both in typical operations as well as in response to grid disturbances.” = more data + modeling needed.

It’s a signpost that grid planning + op are entering a new paradigm. System operators are rethinking how to maintain reliability in a BPS where inertia is no longer free and stability must be actively engineered.

It’s hard to find a trend in the electricity system right now that *doesn’t* point to near-term rate hikes if not a broad affordability crisis. That’s a serious problem for climate policy, but also the American economy writ large. I wrote about it: heatmap.news/politics/ele...

When it comes to Texas weather, I look to @theeyewallwx.bsky.social to cut through the nonsense. @mattlanza.bsky.social knows his business on this analysis of the tragic TX flash flooding.
The latest on TS Chantal today, but more importantly, we take a deep dive into the causes and forecasts leading up to the horrific flooding tragedy in Texas. A lot to unpack today. open.substack.com/pub/theeyewa...
