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.

Remember it takes at least as much energy to pull the carbon back from the oxygen as how much was released when the carbon was burned and bonded with the oxygen. And because of reasons it's more like 3 to 4 times as much and because humans aren't that clever it's probably closer to 10 times as much.

This means we have to pay the bill to put back all of the carbon from fossil fuels we've been burning for the past 100 years. This is an amount of money we can't even begin to fathom. And because we are slow at it, we also get taxed on top of that as climate change leads to economic loss in a variety of interesting ways.

There are no shortcuts, there are no quick fixes. We need to stop burning fossil fuels right now and start fixing shit. Now we have had a pause in the growth of fossil fuel burning, but the rate is still insanely high and at peak levels. Even though the growth has stopped, it hasn't shrunk either. And it's very possible the dip was only due to the impact of covid and for 2024 onwards it will start growing again.
