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.

Hummer EV is just to make you think about your stupid argument. Here's my real argument:

Prius is literally better than EVs for the environment. You can't get rid of these hybrids, they're surprisingly good for the environment.

Banning the #1 best vehicle for the environment because they don't conform to your "insane" idea of environmentalism is stupid. Actually run the math, actually calculate the environmental effects of various metals and the real world turns out to be more complex than braindead "duh go EV" arguments.

You have to run the math, its not as easy as it looks to make good environmental decisions.
