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.

Please don't buy into geoengineering. We need to repair our relationship to nature through rewilding. We should be changing the way we live, giving up large monoculture crop that goes toward animal husbandry and rewilding the planet to sequester carbon emissions. We are in this situation because our ancestors changed the land and the wildlife so radically in our attempts to industrialize. We overfished, killed whales, ran large predators into extinction, removed most old growth forest among many other things. Humans have tried geoengineering before, we dam rivers, flood planes, dig canals, level the earth and introduce species where they are not native, among large chemical, mineral, metal and other injections to the ground, sky and water. The climate models see carbon sequestration, SRM and geoengineering as attractive options because it lets us continue business as usual. We do need rapid change, of the way we live and with our relationship with the earth.

What you don't seem to understand is that we don't have time for that. Unfortunately rewilding will not happen, human greed is too strong, and everyone wants their own back yard. We need rapid and effective ways to get carbon dioxide out of the atmosphere NOW, and iron fertilization may be able to start that process. People can't even stop eating beef for fucks sake, and we know that's destroying the Amazon rainforest.
