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.

Finite Carbon, created in 2009 and bought by British multinational oil and gas giant BP in 2020, is responsible for more than a quarter of the US’s total carbon credits, which it says it generates from protecting more than 60 “high credibility, high integrity projects” across 1.6m hectares (4m acres).

However, experts at the offsets ratings agency Renoster and the non-profit CarbonPlan analyzed three projects accounting for almost half of Finite Carbon’s total credits, with an estimated market value of $334m, according to analysis by market intelligence company AlliedOffsets. Renoster found issues, including trees in a project in the Alaska Panhandle that were probably never in danger of being cut down in an already extensively logged area. Of the credits Renoster looked at, they found that about 79% should not have been issued.

Renoster, a company mostly used by prospective buyers of carbon credits to help them avoid those without real climate benefits, was commissioned by the non-profit newsroom SourceMaterial to examine Finite’s projects. CarbonPlan provided additional analysis.
