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'm more intrigued by the purple zones. 7-14 days late. I live a couple of hundred kilometers north of that big "late zone" next to Canada.

Springs don't feel particularly late to me, although I also don't have any real data. Farmers seem to be in the fields earlier than they used to, leading to harvest starting earlier than it used to. Gardeners don't always wait for the end of May to plant the way they used to.

On the other hand, my record of pellet consumption (we heat using a pellet stove) shows our heating season getting longer. I just assumed that that was because we're getting less tolerant of a chill in the air as we age.
