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.

The NPCC’s latest estimates, for example, project sea levels around the city to continue to rise between half a foot and just over a foot in the 2030s. Annual precipitation is expected to increase by up to 10% in those years, while the city could experience temperatures between 2 and 4.7 degrees warmer.

The estimates, which have not been previously reported, are part of a forthcoming paper from the NPCC Climate Science Working Group and were reviewed during a presentation to a northeast climate consortium earlier this month.

This being the US, those estimates are in Fahrenheit.
