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.

Meanwhile I'm over here thinking anything under 25 is a bit cool, 10 is downright chilly and -10? -10 is Ice Age snuggle up to your wooly mammoth temperature.

It seems they did some work on coming to a definition for "mild weather," but I still don't like what they came up with. They set the range at 10-25 degrees Celsius. I would have set the lower boundary at -10 or maybe even a bit lower. It's somewhere below that the majority of people stay inside their ice-fishing shacks instead of getting out a chair to enjoy the weather.

Of course, the number of people I know in Saskatchewan who think only lunatics go out at those temperatures may mean that they've nailed it. :)
