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.

I hate the argument that nuclear is unsafe. Sure its unsafe, but how is killing the ocean with record temperatures caused by coal and other fossil fuels any safer?

Greenhouse gases are polluting the air we breathe. Seems pretty unsafe to me to be emitting literal metric tons into the atmosphere for all of us to choke on.

Because fuck logic.

While that's true, the counter arguments are Fukushima, Three Mile Island, and Chernobyl.

The risk with nuclear is that we trade one problem--climate change caused by CO2 emissions--for another significant problem down the road.

At the same time, climate change is here now, and we need to act or else there isn't going to be anything we need to worry about in a century.
