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.

The Arctic region has been a massive store of carbon for thousands of years. Now it's warming between 3 and 7 times faster than the global average and that carbon is escaping into our atmosphere. The latest research suggests that more than a third of it is now a net emitter! And in case you're wondering...that's NOT good!

Bunkers are a scam. They're fine for some occasional wildfire or flood, but not for climate chaos and all the damage that will do to society. Having a bunker just means you die later, perhaps after you eat your bunker mates, or they eat you. It's not like they'll "repopulate" after, climate change is going to go on long after 2100 and these inbred clowns will just inbreed more until they die off.
