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 Biden/Harris administration did a lot, starting with Harris casting the deciding vote for the Inflation Reduction Act., a key piece of climate legislation. We even saw major cuts to the leasing of federal lands for coal, as well as big cuts to oil and gas leasing

By contrast, Trump appointed a coal lobbyist to run the EPA and took steps to increase not just greenhouse gas emissions, but a wide variety of human-impacting pollutants, is surrounded by people who want to eliminate any effort to address the climate problem, and solicited a billion-dollar bribe from the oil industry

Harris may not have done enough yet and some of the language she uses about fossil fuel extraction is designed to appeal to people who still depend on oil to get to work, but the choice is very clear. Vote for Harris — and volunteer if you can
