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.

We’ve observed that the climate has changed for millions of years on this planet.

Yes, and scientist have a pretty good understanding why it has changed in the past. Just as now we understand the climate has changed because of increased carbon dioxide in the atmosphere. Can you guess why there is more carbon dioxide in the atmosphere now than before the industrial revolution?

The post Industrial Revolution is the teensiest-tiniest microscopic doesn’t-even-register slice of time on the scale of the entire time this planet has had a climate.

Yes. And still, in this tiny slice of a time, the climate has changed a significant amount.

Just look at how climate change is being used by politicians and leaders.

Why should I look at politicians on a science matter. That's your problem. You should get your science from the scientist, not politicians.
