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'm too tired to link stuff tonight but if you want to join team hopeless, look up the remaining square km of ice cap coverage and how much ice we lost this year, and then look up the Blue Ocean Event.

In summary: another five years as hot as 2023 and the ice caps will be depleted to the point where the oceans absorbing all the unreflected solar radiation will cause the release of massive amounts of methane from the sea floor that will cook the earth in its own atmosphere.

Fuck the police and all, but it's a little late to be protesting this.
