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.

Did we ? Some species managed millions of years, we're at what 100k-150k or so, seems a very shitty run really.

Jokes aside, I suppose we're not witnessing the end of humanity, just the end of this civilisarion. Pity we're taking so many other species down and leaving the place in a fucking mess.

In all seriousness, I think the reason why we are in the situation we are in is that, for about 50 years, people have ignored the worse scenarios and paid attention only to the ones that aren't that bad. That isn't the correct way to manage risk.
