Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Big tech never had net-zero goals. They had PR campaigns, and they no longer have to pretend they care, because AI is the potential payday they're putting all their effort into making a reality.

If it weren't for regulation and financial incentives from governments, they wouldn't have done almost any of what little they have.

I dont think AI has much to do with them dropping the greenwashing, it's kissing the ring to Trump. If Harris had won they would still be going just as hard on AI but trying harder to keep the green messaging going.

Never forget that the one time the tech industry had a chance to decide are we for or against humanity it chose AI or the oil and gas companies over the planet and humanity.
