Really great to see this presentation of this paper by two giants in the field @DrKateMarvel and @markjwebb on a real lowdown on ECS.

This is the most important post on X right now. It should also be noted that in a few decades of zero fossil fuel use the methane levels would decline enough to match this. But the decline in aerosols would raise temps by much more and more rapidly!
It's not this simple, but for basic understanding: For Earth's Energy Imbalance of 0.86 W/m² to go to zero through increased Planck Feedback (= OLR) alone, temps would have to increase by another ~0.27°C (0.86/3.22). Which would result in a temp of ~1.9°C above 1900!

Can anyone point to a case when university lab scale research received a bunch of buzz and press, and then actually delivered on its promise at scale? This powder removes as much CO₂ from the air as a tree - Los Angeles Times

Berkeley chemists have created a reusable material that pulls carbon dioxide from the air and holds onto it until it can be stored.

Many cities around the world installed Dance Chimes, a foot-operated chime-like musical instrument that consists of 9 bronze tiles, with mechanical sound elements under each. This is in Magdeburg, Germany, where dogs love it so much. [📹anosch100] https://t.co/tV8jc1fIpB

If we cant keep warming to 1.5C, we can simply 'overshoot'. 🌍🔥🌡️🏹 The idea goes as follows: we temporarily exceed 1.5C before returning below it at a later stage. In a new paper @Nature we show how overconfidence in our discussions hides the deep risks of such strategy. /1

to be completely fair, Joe Biden didn't bemoan his pick of Merrick Garland because of his unwillingness to actively pursue a conviction of Donald Trump for his attempt to overthrow the election but rather because he allowed the investigation of Hunter Biden to go forward.

August 2024 Temperature Update The global average temperature in August 2024 was the warmest directly measured August. The 15th consecutive monthly to break or tie monthly temperature records. Almost certain that 2024 becomes the new warmest year. https://t.co/fWXVu3nBH2 🧵

@LeonSimons8 As far as I know, the aerosol forcing impact does NOT include a suppression of the lapse rate feedback (which is well documented) and the (theorized) suppression of regional cloud feedbacks over oceans.

“But that leaves other questions unanswered, like: why wasn’t growth increasing enough to allow the ruling class and the working class to accrue income and grow together as they did before, in post-war capitalism?”

September 2024 was the second warmest September on record, coming in just above 1.5C relative to preindustrial levels in the Copernicus/ECMWF ERA5 dataset. It was a ~0.3C warmer than any September prior to 2023 (which set an extraordinary high bar):

we are soon going to receive word from Gavin Schimdt and others that something not included in the climate models is being revealed, that this excess temperatures while going into a La Nina is unprecedented and that we have blown well past 1.5C already.
🌊🌡📈 >🌀 Global Sea Surface Temperatures reached record daily highs again, while El Niño has ended. We might have to wait a while for updates, because the @NOAANCEI office was hit by flash floods, due to Hurricane Helene, which was strengthened by record Sea Temperatures!..

Is there anyone still in doubt about the fact that the hydrogen economy was always a pipe dream?
@skdh The hydrogen economy is a pie in the sky. Mainly people who can't differentiate between energy sources and energy carriers fell (and fall) for it. https://t.co/xywEg9CpNB
