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.

But clearly this is just a natural thing. Why, desert plants are KNOWN to burn up during natural shifts in climate, ESPECIALLY after an ice age ends!

@.@ Guess what dumb ass argument I hear a lot for why the summers are getting hotter

The thing about human-induced warming is that it has a rather pronounced effect at night when the planet is trying to shed the heat built up over the day and no longer can as effectively.

I am not a botanist, but I wonder if desert plants are adapted to take advantage of the cool desert nights to recover from the intense daytime heat? If so, I could see where they would be in trouble now.
