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.

Buckle up, it will get worse.

By how much is a human decision though. The bulk of coal, tar, oil, and gas are still in the the ground. There are forests yet standing. Cattle are the bulk of mammals.

We can choose to leave fossil fuels in the ground unburned. To manage forests to keep them around. To shift away from eating animals. Do those, and we can limit the damage.

It's a human decision as it's humans who can make this decision.

However it's a decision that only a very small minority of humans can do, most of us have no say in this.

Most us aren't the final decisionmaker but have a lot of ways to out our thumb on the scale to influence the outcome
