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.

Yet anyone I speak to is thrilled to not have winter weather to deal with. I have to bite my tongue to stop ranting about how it's not good.

Similar thing is happening where I live too. Living on the Great Lakes, we're usually being dumped on with -20 to -40 degree temps. Right now, we're barely below freezing and there's no snow on the ground. The Lake is struggling to freeze and we're at that time of year where it should be close to 100 percent ice cover by now.

We have a lot of events this time of year that are dependent on ice (Ice fishing tournaments, ice races, marathons where you hike across the frozen bay), and I think all of them have been canceled. It's crazy, I've never seen anything like it

Yeah I'm in southeast Michigan, and I'm missing wintertime. I really don't like summer, so I'm screwed.
