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.

This is a great post, but I would like to point out that Douglas fir are not part of the monoculture problem. These are native trees, forests.

I understand that. However logging is taking out fir forests and replanting with pine and spruce. I hazard a guess that if the biomass were left alone less issues would occur given those primary forests have thrived for a very long time on their own.

That does seem likely. I just wanted to clarify for those who aren't so familiar with the region and its trees.

The first are native but all non profitable tree species have been pushed out. That area of Oregon was most likely predominantly pine a couple hundred years ago.
