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 think precipitation has increased, but water is having a hard time freezing.

Yeah currently, but if the Gulfstream slows down Europe could get colder by earth getting hotter.

Favorite fun fact, the people of Paris live farther north than about seventy percent of all Canadians. Without the ocean currents that are currently slowing down, well suffice to say that even southern Canada is not known for its mild winters full of cool rain.

Climate change is not scary because the temp is two or three degrees warmer than it was for our parents, but becuse we can expect far more energetic and inconsistent weather all over the place, making farming and building more difficult and dangerous. That temp change is not evenly distributed, and indeed one of the effects of climate change is that parts of the earth are actually getting colder than they were at preindustrial carbon levels.

Yeah and paris is a pretty much in the center of Europe (north south axis) yet currently we have Floods all over Europe and not meters of snow...
