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.

Let’s Not Kill 450,000 Owls: It’s a testament to human arrogance and cruelty that this is even being considered. (www.currentaffairs.org)

For those who are coming straight to the comments, essentially the Fish & Wildlife Service is proposing culling tens of thousands of Barred Owls in order to prevent them from displacing Spotted Owls. The issue is that landowners can also apply for a culling permit, and the two species are close enough in appearance as to be indistinguishable from each other (especially at night), which means Spotted Owls are just as likely to be killed as Barred Owls.

In short: a good intention, a very bad idea.
