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.

Slash and burn ag is so stupid...

From Wikipedia:

The productivity of the soil following forest removal for farming lasts only a year or two before the fields become infertile and farmers must clear new areas of forest to maintain their income. In 1995, nearly half (48%) of the deforestation in Brazil was attributed to poorer farmers clearing lots under 125 acres (0.51 km2) in size.

They typically grow crops on the land at first, then due to poor soil management it becomes useless for crops so they put cattle on it and burn down more forest to grow more soy or whatever.

Then again. Big picture time.... We're globally releasing enough GHGs that it's equivalent to burning down the entire Amazon rainforest every two months.
