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.

It's always just been another excuse to keep the economic status quo. We've had all the technology we need for a long time to solve emissions. We're not waiting on any battery tech breakthrough that can sustain a renewable grid, hydroelectric has been doing it this whole time. Motor pumps water uphill, water turns generator when it goes downhill, congratulations you have stored renewable energy with water and a hill. Use pulleys and weights, use tanks and air pressure, whatever you want, it just has to be built. There's no missing link here, it's just boring and doesnt have much opportunity for tech startup investment.
