Climate - truthful information about climate, related activism and politics.

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.

If we actually succeed, we end up with a decarbonized electric grid too, and the big EV's emissions drop to zero.

I do agree that huge vehicles should be discouraged for personal transport, but that's for livable-cities reasons, not climate.

Hummer EV is literally worse for the climate.

This isn't even some "theory" I'm trying to show you. Its real. This is a real vehicle that's causing more pollution right now in our country and world to measurable effects.

If we actually succeed, we end up with a decarbonized electric grid too, and the big EV’s emissions drop to zero.

Lithium is made by pouring acid down mountains and collecting the acid that leaks out. There are incredible environmental effects you need to account for in the creation of EVs, even if we had a 100% decarbonized grid.

In fact, a 100% decarbonized grid would likely favor H2 (Hydrogen) vehicles since those have fewer environmental effects in the production process. And H2 can be made out of just electricity and water.

The number of hummer EVs being built is tiny.

You're concern trolling at this point.

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.
