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.

I think they're covering scope 1 and 2 emissions, but not scope 3. That is to say that they're trying to limit emissions during extraction, transportation of fossil fuels, and refining (and from the electricity those use) but not from when the fossil fuels are burned.

TLDR: Pasture in former forestland, such as New England, can quickly be returned to forest, soaking up carbon. There is an interesting opportunity for synergy here, as removing cattle from a relatively small amount of land can have outsized impacts compared to the larger grazing areas in the prairie by pairing the removal of cattle with reforestation. These high opportunity areas could be a highly effective investment and much more financially and politically feasible.

I do not believe this includes scope 3 emissions.

Opponents — including plenty of former global warming deniers who have rebranded themselves as economic pragmatists — have cast these steps as too ambitious, too costly or both. Which is to say, we can’t afford to save the planet.

To put it as soberly as we can, it’s that same old suicidal nonsense recast to pass for common sense.
