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.

Of course there is an alternative, as the article is arguing implicitly, you ban mining and other unsightly industrial activities in rich areas with strong environmental and safety laws, and outsource it to poor nations without the political leverage to strongly regulate mining companies. This objectively results in far, far more environmental damage, but that environmental damage is contained to highly populated areas full of poor people you don’t have to think about.

I really wish more environmentalists were pushing for potentially environmentally hazardous processes to be moved to areas with strong regulation and environmental protection laws, instead of just pushing them onto poor people, but unfortunately a lot of people seem to be so (purposely) disconnected from the industrial processes necessary to make everything from wind turbines and trains down to the food that appears on the shelves that they view the mining and manufacturing of these things as completely unconnected to these things themselves appearing in their lives.

Fucking preach. Very good point about pushing mining impact into "more friendly" regulatory environments.

The disconnect is baffling in a lot of industries.

That's a very good point. It's pretty damn sad at how disconnected many of us are to the processes that get us everyday things.
