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 imagine there are many US people living in places with 100+ degree days for months in a row -- Places which seldom got above 90 a half-century ago ... who do not understand that driving a car with AC to a home with AC is making matters worse.

The situation is urgent, yet we keep hearing 2060 2050 2040 2030 deadlines as if a fix could somehow be delivered by then . BUT: If we got to zero -tomorrow- , it'd stay as it already is for centuries. Every day without HUGE changes NOW it's getting worse.

Too be fair, it is not the choice of individual Americans to live in and be dependent on a society that was forced to become car centric and dependent.

With very few options to travel by car, and the large dominance of single family homes, we don't get many options.

Fuck people who drive gas guzzling trucks and giant suvs though. That is just unnecessary. But again car manufacturers have been slowly convincing Americans to purchase larger more expensive suvs for obvious reasons.

This issue is absolutely a governmental policy choice, and one that is continuing to be upheld.
