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 think the difference is that, at least when I took a class on this (coincidentally about 15 years ago), we talked a lot about how there was likely to be a runaway effect. This article is saying that the climate measurements from the last 15 years provide evidence that the predicted runaway effect is, in fact, happening.

I would like to buy 50 years time please ๐Ÿฅบ, if people can wage war, build monuments, AI and trains all in under 30 years then we still have some what a slim chance of working through some of the climate change problems without committing mass suicide of some sort

Why mass suicide when we can mass guillotine the billionaires instead?
