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.

Birds in the United States are not only declining, but they are declining faster, especially in areas with intensive agriculture, according to new research. Overall drops in bird population, measured from 1987 to 2021, were sharpest in warm and warming areas, suggesting that climate change may play a role.

...

“What we found is that any metric of agricultural intensity was always the best predictor of acceleration of the decline.”

It wants to lower wholesale prices by reimbursing power generators for the carbon permits they have to buy, and recover the cost directly from customer bills. Consumers would then only be paying the carbon tax on 40 per cent of their consumption instead of 80 per cent. The net benefit for consumers is expected to be about €10/MWh, while the government and gas-fired plants would see little difference.

Back in December, the retraction of a key climate report was seen as proof that the economic cost of global warming had been overstated. Now, Norway’s wealth fund says its own analysis indicates that would be the wrong conclusion to draw.

This is above and beyond what overfishing does. Per the article

“Historically, overfishing has been the main driver of biomass declines in many of the world’s fisheries [and] according to the FAO [UN Food and Agriculture Organization] the proportion of overfished stocks globally continues to rise,” said Ortuño Crespo, who was not involved in the study. “The current challenge is that this overfishing crisis is being further exacerbated by ocean warming and deoxygenation.”
