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.

Yes, this means a ton of carbon ends up in the atmosphere instead of in the trees. The right move would be thinning and prescribed burns, but this administration isn't going to do that.

So I just want to chime in here as an outsider. From what I searched, national forests are different from national parks in that, extraction of natural resources from national forests is permitted for commercial and personal use.

Trump's order cites wildfire, insect and disease outbreak as the reason for this change (Biden also sought more logging to combat fire but apparently timber sales did not change much during his tenure). While I agree that forest management is important, Trump had also put tariffs on Canadian lumber and cut down jobs for national park workers. It's not hard to question if there are other motivations other than wildfire prevention in this context.
