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.

January 2024 is also the eighth month in a row that is the warmest on record for the respective month of the year, according to Copernicus.

"Rapid reductions in greenhouse gas emissions are the only way to stop global temperatures increasing," says Samantha Burgess, Deputy Director of the Copernicus Climate Change Service.

Yay, we reached the 1.5° goal ahead of schedule!

I think they recently mentioned we’re a little above ~1.7°

Hey I remember when we were supposed to pass that until 2100...

And 2050...

1.5 is so 2020. The new limit is 2.0.

So it started as a limit to not surpass. Now it's a state we should be trying to get back to. Yippee . 😠
