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.

Yes, because the world is extremely complex. The sadder thing, is that even if we solved climate change tomorrow, we'd still have a few other ways for our planet to end, including destruction of soil habitat, loss of biodiversity, and literally dozens of pollutants like BPA and glyphosate, dyes for clothes, microplastics, heavy metals (including from tractor tires&exhaust right onto the fields we grow our food in)... And we have an outdated representative democracy that doesn't utilize our country's education or expertise. Frustrating. It's not the time of horses any more, we can fucking use technology now ya'll. We should be able to vote and discuss policy en masse from our homes/cell phones. We don't need representatives if we are literally our own representative in a true democracy.
