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.

From the article:

The last coal producers in New England will shutter their doors permanently under an agreement reached with environmental groups and the Environmental Protection Agency (EPA) on Wednesday.

Two plants in New Hampshire, Schiller and Merrimack, will voluntarily cease operations in 2025 and 2028, respectively, said Jim Andrews, president and CEO of Granite Shore Power.

By closing the plants, Granite Shore Power — the company that operates them — resolved litigation brought by the Conservation Law Foundation and the Sierra Club, which alleged they violated the Clean Water Act.

The region’s coal-free status comes as part of a larger pledge by the U.S. to phase out coal power plants through the Powering Past Coal Alliance. The U.S. joins 56 other nations in committing to no new coal plants and the closing of existing operations.

The U.S. has not named a target date for completing the transition, but the Biden administration, through other works, has indicated a plan aimed at no coal by 2035.

New Hampshire will become the 16th coal-free state in the nation, according to a statement by the Sierra Club.

Facilities like Merrimack have fallen short of emissions requirements in the past, exceeding one emissions limit by 70 percent in 2023, according to reporting from New Hampshire Public Radio. Previous failures to meet requirements did not inform the company’s decision, Andrews said.

He has said that new “renewable energy parks” of solar arrays and storage facilities will be developed.
