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.

Except that "there are 26 climate feedback loops that are ignored by most models" is a clear misrepresentation of what the article you linked to actually says, which is that this scientific team has identified 26 amplifying feedback loops, including some that the researchers say may not be fully accounted for in climate models.

"Some may not be fully accounted for" is a far cry from "ignored by most models". Spreading this type of false narrative on climate science only helps the people who use the "we don't know enough about the climate to take any action" excuse, please don't contribute to it!
