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.

We’ve only had 1.3C of global average warming, but it’s enough to popularize the entire category of personal cooling devices. So when people say, “You won’t even notice 1C of global warming,” the market tells us that that’s absolute bullshit.

I can't imagine they would last long. There is this device my wife used after surgery that runs ice water through a tube to a wrap on her recovering area on and off circulation so its only going 50% of the time. Had a huge resevoir I would empty water from and fill ice into. It was crazy how much ice I had to make and constantly replenish and she was in a comfortable envirnment resting in bed. Can't image how someone being active and out in the heat with something covering way more body surface area is going to have it last long and they would need to be near a constant source of ice.
