Global Climate Politics after the Return of President Trump - Volume 79 Issue S1

Bill Gates, Tony Blair, CFR are rethinking climate change in the Trump era: more "realistically." Can we dismiss this trend or do we need to understand what it means global climate politics? 🧵

I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.
They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

Who among us fully understood the extent to which the loyalty vs. competence tradeoff for government appointees was such a crucial guardrail for democracy? Few since Hannah Arendt.

The current historical moment - esp. embodied by the return of President Trump - has let pundits push a need for so-called "Climate Realism".

Many people think about cold in Northern Europe if the Atlantic Ocean current system #AMOC fails. But that wouldn’t be the only problem for Europe by far.

📢 New paper on the impacts of AMOC collapse on European hydroclimate. 🌊
We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe.

Alas: even if Anthropic stole your work, you can only make a claim if your book was registered with the U.S. Copyright Office. Most Canadian🇨🇦 publishers don't (or didn't), because the legal copyright exists even without registration. So Anthropic gets away with it ... unless there's a new lawsuit?
Hey authors! Check to see if Anthropic stole your book to train their slop generator on. You’re entitled to $1500 per stolen Work.

The International Criminal Court is ditching Microsoft Office, saying it’s too dependent on US tech, in favor of Open Desk, a German open source alternative.
The move comes after Microsoft revoked ICC head Karim Khan’s email access when he was sanctioned by the US for the warrant against Netanyahu.

Clean Energy accounted for all electricity growth this year. Gas/Coal were basically a wash and will be for years to come for electricity generation.
We need to ramp up batteries because they are 90% cheaper than distribution grid upgrades which is the main reason we have rate increases.

For energy nerds it’s the annual “explain how IEA scenarios work” day..
1/ those are not *forecasts* about energy use
2/ comparing scenarios with different names is pointless
3/ Faith’s words should be parsed very carefully; be wary of short quotes

Home insurance is getting less affordable, and less available, as insurers raise prices and pull back from areas with extreme weather. That's forcing families across the country to make tough choices. n.pr/47QGKwH
It's harder to get home insurance. That's changing communities across the U.S.

In case Ezra Douthglesias is looking for things that voters support far more than the six pet issues with yellow check marks around which to organize the Abundance of Popularism Agenda:
By a 2 to 1 margin, Americans say Trump has gone too far in trying to expand the power of the presidency and lay off government workers. And by large margins, they say he has gone too far in sending troops into cities, attacking universities and ending DEI programs.
3 in 5 Americans disapprove of Trump's job performance, the highest level since after the Jan. 6 attack. Americans disapprove even of his handling of issues historically favorable to him like immigration, crime and the economy. www.washingtonpost.com/politics/202...
