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.

40% of global ship traffic is simply moving fossil fuels around! Renewables make much of this traffic obsolete (slrpnk.net)

Could also reduce the shipping needed on these by requiring standard container shapes that can properly be emptied. So many consumer product containers, even food containers, are designed so it is difficult to fully use the product. Companies see it as an uptick in sales because you'll be buying that soap/ketchup/whatever more frequently since you can't use 4 ounces out of the bottom, rather than seeing the cost-savings of not shipping 4oz x thousands of containers of weight pointlessly. (Personally, I go out of my way to empty every container fully, but many see it as a waste of effort.)
