alt Hacker NewsNot much of a surprise. Government action has been anemic at best. Industry action (overall) has been net negative.
The only hope now is exponential growth of (solar and wind)+batteries making other sources uneconomic. This seems to be slowly happening, so I hope we hit the exponential curve soon and we're there quicker than we expect.
This only stops it.
Then, to fix it, we'll need a massive Direct Air Capture industry that will have to operate for a century, and probably past that so we can hit and maintain a CO2 level of 250ppm.

And individual action has switched to just holding governments and industry responsible. Which basically amounts to giving up.
"Welp, just gonna buy this truck, enjoy my burgers, set the AC at 68 and fly on all vacations this year because it's nothing compared to Big Oil."
I have been wondering: more solar means we are making Earth less reflective. Solar energy that might have been reflected back to space is now absorbed by the PV to make electricity. But that delta has to go somewhere? Where does it go in terms of Earth’s temperature. Same with more nuclear… we’d be pumping more energy into the system.
Don’t take this as an argument against these technologies. It’s a huge win to not be increasing the CO2 concentration in the atmosphere by burning fossil fuels.

I am not very surprised, since the people voted for the "drill baby drill" president?
I wouldn't classify that as anemic.
Direct Air Capture at any meaningful scale is predicated on mining billions of tons of refined minerals. The environmental impact of that would be so enormous that it will never be allowed to happen, never mind the severe resource crunch.

Removing CO2 from seawater would be more efficient because some of the work is already done for you, and you'd be de-acidifying the ocean long term.
It is quite ironic that capitalism and the profit motive are now the best hope for staving off climate change, all thanks to the technologists and entrepreneurs that have mad renewables and storage so cheap.
The 2020s climate action movement in the US (and the UK) was disastrous in their strategy, action, and outcomes. I was there, I followed along because it seemed like the best way to get climate action, but things like Sunrise and XR at their very best did nothing. They focused on all the wrong people, focused on all the wrong levers. They turned allies into enemies, by "protesting" tech companies that were at the forefront of real action. They refused to acknowledge the massive effects of technology change, and the need for quick adoption, and the huge money saving nature of the solution.
I have zero patience for those attitudes now, the difference between a degrowther and a climate change denying politician are minimal in effect, and the effects are all that matter now.
The technology-will-save-us mentality is part of the reason we are here. We live in a society that doesn't do anything unless it makes money for some set of decrepit old men.
We had the means to avoid this (strict vegan diets, ground based mass transit, dense development & re-wilding, energy transition) but people made money doing the opposite. And more people made money sabotaging solar+battery pricing in the US.
So we get to watch the world burn down around us.
