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.

What I think will end up happening is a lot of fracking and a simultaneous growth of renewables. There's money to be made in both, but renewables aren't limited by finite resources, so they're the future while the oil companies squeeze as much fossil fuel (read: money) out of the earth as they can in the meantime.

Luckily the finances have got a point where renewables are a no brainer. Hopefully they'd struggle to stop them if they wanted to. The big fossil fuel companies would be stupid not to invest in both.

How do you think we turn the unlimited source of energy into power? With rare resources!

For now. That's not guaranteed to always be so, but we already know the hard limitations of fossil fuels.

We need to reduce our consumption, but no one wants to discuss the hard stuff.
