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.

“While no one strategy is a silver bullet, our results provide clear evidence that we should begin by prioritising the forests we have left,”[...]. “And protection must go beyond avoiding deforestation. Avoiding forest disturbances from wildfires or logging delivered the greatest benefits for forest biodiversity.”

No single intervention was sufficient to reverse biodiversity and carbon losses across the entire study area.

“Restoration is essential where forests have been lost across large areas. But our study shows that investing in new forests makes little sense if, at the same time, we fail to protect existing forests,”

The paper: Protecting tropical forests is more cost-effective for biodiversity and climate than restoration

just one more reason why, if the roadless rule goes away in the u.s., it will be bad for all of us.
