It could cost the US $100 billion a year.

    Trees do it.

    Plant more trees.

      I’m all for more trees but they eventually decompose and release their captured CO2. Combine it with BECCS and it could actually net in reduced CO2 over the course of centuries. We’ll need a myriad of solutions, unfortunately a lot of capture methods are greenwashing bs.

      It takes decades to get significant co2 out of the air with trees.

      Algae is what we want. Then toss it down a coal mine.

        So we better get it going, then.

          I hear it’s better if we start 20 years ago.

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.
