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.

Does Burning Wood Actually Fight Climate Change? Despite industry claims, scientists say using wood pellets is little better than fossil fuels. (thetyee.ca)

as the change in forest cover associated with that conversion results in similar emissions

It doesn't. The Amazon is still massive. Land use change had turned the Amazon into a source and not a sink of carbon.

You can burn all the trees you want... Again. This is conserved. The carbon released will grow exactly that amount of new trees.

Unless you also stop the cycle. Then we're really fucked.

Like 116F... Plants die. If the equatorial or other regions hit that consistently, desertification is guaranteed.
