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 remember being in 4th grade around 28 years ago. The big thing back then was FCKW and the ozone hole. I specifically remember my teacher talking about global warming and what it means. He ended up with: "it happens so slow that we're not even gonna see the impact it has."
Back then, we would go to school on skies a bunch of times in the winter. We had 60cm snow over night on some days.
Fast forward 10 years, there was not enough snow anymore to sky. Fast forward 10 more years. It snows maybe twice a year for a total of a week. Present day, we have snow like every other year.
