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.

The science wasn’t in question. The journalism has catastrophically failed.

It's always amusing when people on lemmy complain about journalism while making it abundantly clear they didn't actually read the article. Nobody said the science was in question. But the problem is, you'd have had to read the article to know that. Oh and for the record the article was written by the researchers themselves, Beverly Law, Professor Emeritus of Global Change Biology and Terrestrial Systems Science, Oregon State University and William Moomaw Professor Emeritus of International Environmental Policy, Tufts University. With contributions from Richard Birdsey, a former U.S. Forest Service carbon and climate scientist and current senior scientist at the Woodwell Climate Research Center.
