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.

Taking CO2 out of the air would be an absurdly expensive way to fight climate change (www.theverge.com)

The tricky part is keeping the carbon in the plants. My grass clippings will decompose back into CO2 if you just dump it in a pile. A better option would be to dehydrate the clippings and bury it in a cave or something.

I also understand that there would be better plants than grass as well.

What if your grasses decomposed and were put under pressure by rocks inside said cave, slowly transforming into a rich, dark to jet black liquid hydrocarbon substance or something like that?

That would be pretty strange. Millions of years of stored sunlight and carbon, just liquefied and pumped underground on purpose.
