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.

Humans probably shouldn’t be living in these conditions if they can’t survive without AC, no?

Would you say the same about places where it gets well below freezing in the winter?

Edit: Many older houses don't have AC in Vegas. They use evaporative cooling mostly.

So they waste more water but less energy.

Colder climates have their challenges, but tend to have more energy-efficient solutions than hot ones. Then there ae the wonderful places with brutally cold winters and boiling summers, so you get the worst of both worlds.
