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.

To add to the list:

Here in the Northeastern US, weather patterns seems to shift forward. It stays hot till October. Even November might have a few summer-like warm days. And "It's beginning to look a lot like Christmas" is ironic since there was snow on Christmas only 2-3 times out of last 10 years or so. Snow comes in mid-January

This 100% tracks with my experience in the northeast US. It wasn’t like this when I was a kid in the 90s. Having a “white Christmas” wasn’t common, but it did happen sometimes.

Nowadays Christmas tends to average around 50°F/10°C where I am. If there’s snow before January, it’s a brief flurry that either doesn’t stick or changes into rain. My nephews have never known a snowy Christmas.
