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.

According to a report by Bloomberg, the project generated more than $100 million in revenue after being set up over a decade ago by South Pole, a major Swiss carbon credits broker, and CGI, which is run by a Zimbabwean businessman. South Pole walked away from Kariba in late 2023 when Verra suspended the project and began an internal review following an investigation by The New Yorker magazine.

Nearly two years later, Verra announced last week that its review had found 57% of Kariba’s nearly 27 million credits were issued “in excess”. That is because the actual deforestation observed in a reference area chosen by Kariba’s project developers to predict how much CO2 the scheme would conserve was “significantly lower” than initially estimated, Verra said.

The value of promises.
