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.

Thanks to @KoboldCoterie@pawb.social for highlighting this bit:

Then there were “super-emitters” with extremely high overall greenhouse gas emissions, corresponding to about the top 0.1 percent of households. About 15 days of emissions from a super-emitter was equal to a lifetime of emissions for someone in the poorest 10 percent in America.

so people who own large businesses like cruise lines, container ships, trucking companies, power plants, are responsible for the emissions. it makes sense but attributing all of emissions to that 1 person doesn't account for a board of directors and shareholders who also can have a major say in how much they pollute.

is it at all possible that it is actually people ordering cruises and shit being delivered from china who are responsible? they are not sailing these ships there and back just out of spite. we are paying them.

The owners vote on the board of directors every year, so they do have control over policy like that.
