We have reached 1.4 degrees celsius #globalheating according to NASA data (smooth black trend line). Breaching 1.5 is now inevitable. From now on the fight is to keep overshoot as small and short as possible.

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead.

You can’t reboot the planet if you crash it
What Gates is putting forward aren’t legitimate arguments that can be made in good faith. They are shopworn fossil fuel industry talking points.

Here are my three truths about climate:
1. We fail if we don’t end free-to-pollute fossil fuel model. Period. Game over.
2. A crash looms, prefigured by collapse in home insurance/mortgage markets.
3. There are true villains in the story, and we have to tell it that way.

The degree to which the fossil fuel industries have clocked the populist far right as their last chance to slow the energy transition - and is funding them to undermine it at every step - is one of the biggest stories in global politics, largely and widely ignored.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

Working in some nice valley oaks (Q. lobata) today in the Tehachapi range. There's almost no seedling/sapling recruitment in these old stands -- due to exotic grasses, livestock grazing, lack of fire, climate change, etc. Once these trees die, another piece of 'old California' will disappear. 🌏
