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.

Companies are buying up cheap carbon offsets − data suggest it may be more about greenwashing than helping the climate (theconversation.com)

It's even worse. The places that sell carbon offsets are often poorer parts of the world. The selling is essentially a privatization of carbon sinks. As is tradition, these privatizations are very under-priced. Worse still, as they're selling carbon sinks, they will not have those carbon sinks for themselves in the future if they choose to "develop" and emit more GHGs... they'll have to buy carbon credits from some other fools and the prices are not likely to be lower.

It's all very silly.
