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.

I wish we’d stop calling it climate change or global warming, that implies this is natural instead of big oil lying to us. Call it what it is, ”big oils climate plan”

That's just erosion. It's what happens when you build on coasts. Climate change is something else entirely.

Storms increase in intensity and frequency with climate change, increasing rates of erosion. Most homes built to survive any weather except the worst storm of the past 10,000 years will not survive this century.

Warmer temperatures got ice melting. This raised sea level a bit, and increased the rate of erosion

Yes, but scale and diversity of phenomena are going to be spectacular. Building and losing shitty homes on coasts doesn't really do the topic justice.
