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.

Honestly, the whole concept of "recycling" plastic feels more like a PR strategy than an environmental solution. If it were genuinely effective, we’d see investment, innovation, and accountability—like we do with metals. Instead, we’re handed the guilt while corporations keep pumping out garbage.

Much like the concept of a carbon footprint, it exists solely to make consumers think they can make an individual difference so they won't push for regulations

Yeah I especially love that one everytime I fly. I get to choose the environmentally friendly option with lower carbon footprint for more money. Who the fuck they think they are kidding? We are all in the same plane burning fuel at 10000 m.
