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.

A rapid end to burning fossil fuel would arrest the heating that has caused extreme damage in recent weeks; and that rapid end is possible. (www.newyorker.com)

I think we all know rapid change is possible if the right motivators are there. Not sure how you get people and legislators to make the rapid change we need.

A few things we can do as individuals is fly less, eat less meat, drive less (where possible).

On a larger scale, write to your representatives, and vote for people who actually put climate change at the forefront of their agenda. It's now time for us all to be really pushy.
