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.

Is “air lines” really two words? I could’ve sworn it was “airlines.”

Idiots. Anybody who thinks Trump's madness will stop the switch to renewable energy is a fool. The economics are completely unbeatable at this point. Anyone who doesn't go with the times will be left behind.

invest in Green Energy, or don't invest in anything at all. this has been the economic reality for 20 years. but investment firms aren't truly rated on their 30 year prospectus, they're rated on their last quarterly earnings call. so everything is getting squeezed at a local maxima and eventually we'll all be the bag holders
