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.

Today the Environmental Protection Agency launches two grant competitions aimed at financing clean-energy projects across the country, particularly in disadvantaged communities that have struggled to attract private investments.

The grant competitions will dole out $20 billion under the Greenhouse Gas Reduction Fund, commonly known as a “green bank,” established by the Inflation Reduction Act. They come as the EPA races to stand up the green bank despite several obstacles, including depleted staffing levels and House Republicans intent on repealing the spending.

Yet in a short interview yesterday, EPA Administrator Michael Regan projected optimism the agency would rise above these challenges.

“We are very confident we have pulled together the staff to design and implement this program,” he said. “We have the staff on board; we have the expertise on board. And we feel very strongly that this is going to be successful.”
