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.

Why were the 1930s so hot in North America? Climate deniers sometimes point to heat records from that decade to dismiss the reality of global warming. They’re leaving out crucial context. (yaleclimateconnections.org)

No mention of the Dust Bowl being caused by the removal of deep-rooted prairie grasses for cattle ranching, etc.

The article literally cites "relentless overplowing" as a primary cause. Of course that means removing the existing plants (i.e. native grasses) in the context of converting the prairies to farmland. Not really sure what additional context you are providing, or expecting the article to convey here. Cool pic though.

i missed that, but fwiw I’d prefer it specifically mention the prairie grass. “Overplowing”? What, like you’ve plowed it, then you plow it again? Then you really overplow it by plowing it a third time?

Could be better constructed, imo.
