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.

Dr Henri Waisman, at the IDDRI policy research institute in France, said: “Climate change is not a black or white question and every tenth of a degree matters a lot, especially when you look at the socioeconomic impacts. This means it is still useful to continue the fight.”

and while I agree with the sentiment, we really aren't "fighting" are we, quite the opposite. Every thing we're doing is wrong, how do we know this ? CO~2~ppm is still increasing, fossil fuel use increased in 2023, planes are still droning overhead, cars still driving, more roads being built and winded, the Antarctic is being stripped of krill to make pet food etc

I'm not a scientist, but wouldn't the rise be generally slow enough for people to evacuate, causing more of a concern for refugees from Florida spilling into Georgia, Tennessee, etc? It's still bad but I don't think you'd suddenly have a few million people drown one day.

Maybe once the US sees significant number of climate IDPs, they will get a bit more empethatic to other climate migrants, but sadly the opposite will probably happen.

Mobility is a thing that mostly exists for the wealthy, as far as I can tell. And with the policies that generally exist down south? Fuck em, they’ll sort it out themselves. I live a thousand feet above sea level, they can figure it out themselves.

So again, my empathy goes to the people who can’t move, not the people who won’t move.
