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.

The sound of heads gullibly and gloriously shoved in the sand is deafening for anybody not having their ears full of sand.

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.

There is a very strong likelihood that Trump will force interest rates down mostly as part of his destructive policies, but also influence over Fed. Low interest rates is a huge boost for renewables, because costs are almost entirely upfront. A lower target ROI still supports maximum leverage ratio, and lower energy sales prices to achieve the ROI.
