This is interesting, indicating a possible "positive" impact of an AMOC collapse. However, since the model experiment used hosing, without global warming, it will be different in a case of added global warming. The reduced Hurricane effect was attributed to cooling in the subtropics.

But in the more realistic case with global warming the subtropical gyre would likely warm despite AMOC shutdown and thus the reduction in Hurricanes may not materialize or at least not as much as in the case without warming.

China is pulling further ahead of the US in EVs and clean energy. The US was set to be the global leader in cleantech. Instead, it fell behind, and in the case of EVs, is moving backwards

Trump administration paying an energy company $1.2 billion not to build a wind farm. Bringing total to almost $4 billion in payouts not to add electricity at a time of increasing electricity demand. Dereliction of duty and insane prejudice against wind power. heatmap.news/daily/rwe-of...

heatmap.newsAnother $1.2 Billion to Not Build Wind FarmsThe Trump administration has signed a deal with RWE, a German developer, to cancel more than 3 gigawatts of offshore wind near New York and New Jersey.

Same paper, one sentence earlier doesn’t sound so doomy: “If this relationship persists under future warming, it would favor lower climate sensitivity than recent assessments”.

830 wildfires burning across Canada right now. And you know what’s going to make it worse in the future? More oil pipelines. This is why our voice and our vote matters.

Global warming is making extreme heat more likely and more severe.

This is getting ridiculous. Germany has preliminarily set a new all-time heat record with 41.3°C in Saarbrücken. Until this extraordinary heatwave, the country had never recorded a temperature above 40°C in June. More extreme heat is expected this weekend.
