Climate - truthful information about climate, related activism and politics.

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.

Researchers want to use the ultrafine rock particles left by eroding glaciers — called ‘rock flour’ — to suck climate-warming carbon from the air (wapo.st)

Wow...that's...ironic.

The faster the glaciers recede, the more rock flour we'll have, and the quicker we'll be able to fix the issue!

Do we know how much there is and how much we will need? Seems like a huge problem. Maybe electrify everything and transition the economy to low carbon is a safer bet.

If all of the glaciers recede, we should have all of the rock flour. That should be enough?

It’s a big problem and I don’t know if the science behind this has been tested. Still, every little helps!

We’ll need more! Maybe there is more rock flour on other planets we can harvest.
