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:

A state pollution tax raised $2 billion. Can it survive the backlash? Washington state’s “cap-and-invest” program has generated billions to transition to clean energy. (wapo.st)

Washington’s first year of auctions raised more than expected, generating a flood of revenue for projects to hasten the renewable energy transition and adapt to climate change. In addition to greening the ferries, the money is paying to build and install air-quality monitors in parts of the state hit hard by pollution and wildfire smoke; to replace gas furnaces and install more efficient heat-pumps; and to allow everyone 18 and younger to ride public buses and ferries free.

...

the state’s Department of Ecology estimated an impact of 5 to 16 cents per gallon. But prices rose beyond that — a painful lurch in a state that has long endured some of the country’s highest gas prices. Washington state drivers get most of their gasoline from five refineries in the state, supplied from oil fields in Alaska, North Dakota and Canada.

Just how much the program has contributed to gas prices remains hotly debated. Ecology officials now put the impact at up to 25 cents a gallon. Others, including the Association of Washington Business, say the program costs drivers 45 cents per gallon. At the moment, gas prices in Washington are 32 cents per gallon higher on average than in neighboring Oregon, according to AAA.
