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.

Stopping the climate crisis requires a greater reduction in carbon emissions than is physically possible if every individual were to give up their car and meat, and every mining, energy, and transport company were to be dissolved. The good ending requires 110% of EVERYONE working together.

So if we want to avoid the very worst ending, EVERYONE needs to put in their maximum effort. We need to end pollution at the governmental level, and we need to end pollution at the personal level on our way there. Everything we can possibly do isn't good enough, and that means we need to do everything we possibly can and cross our fingers. There are no more excuses left, for anyone, corporate or personal.
