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.

Americans also largely believe they do not bear responsibility for global environmental problems. Only about 15 percent of US respondents said that high- and middle-income Americans share responsibility for climate change and natural destruction. Instead, they attribute the most blame to businesses and governments of wealthy countries.

You have to admit that PR has done its job well.

Those survey responses suggest that at least half of Americans may not feel they have any skin in the game when it comes to addressing global environmental problems, according to Geoff Dabelko, a professor at Ohio University and expert in environmental policy and security.
