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.

So far, scientists have found that we’re trending toward the high end of those predictions. ... “Presently, sea level is tracking in the intermediate-high to high, the two fastest,” said Randall Parkinson, a coastal geologist with Florida International University. “The other three scenarios, you might not even think about because we’re already rising faster than that.”

Gonna be real funny when that 6 ft by 2100 drops to 2050 and most of Florida become the climate migrants nobody wants.

My in-laws just bought a house near the coast in Southeast Florida. I don't know what they're thinking. Maybe they're too old and stuck in their ways to believe that this will actually impact them? I don't know, but I imagine it won't be long before they can't insure that house anymore.
