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.

On the one hand: fuck AI driving up these emissions for no useful fucking reason

On the other hand: fuck carbon credits - they're universally scams perpetuated by "preventing deforestation" or other inane solutions.

The future solutions are always going to be reduction and drawdown. They're only funding drawdown now, because they're not even trying to reduce emissions.

We do need drawdown in the future but it shouldn't distract from replacing our polluting infrastructure. Kill gas cars. Death to coal plants. Natural gas needs to stay in the ground.

If Google were funding that they'd actually be doing good.

They are. Read their environmental report.

They invested over $3.1 billion in renewable energy projects with an expected combined generation capacity of approximately 4.5 GW. That's twice as much energy as all their datacenters combined.

New power plants take time.
