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.

Yes, it's a huge issue. We need to ban use of vehicles in fields as soon as we are able to wean off them. Tires and exhaust all leave heavy metals and other carcinogenic compounds in our fields which get taken up into our food/crops itself. We need to bioremediate all of our fields and use drone fleets in the future to reduce pollution.

I am always so baffled at how highways are allowed to run next to things like say...great lakes or entire farms and people think "that's the produce I wanna eat!" It also makes gardens in a city feel so sad. But you gotta grow what you want, with what you've got.
