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.

Please read the fucking article...

You completely misinterpret their use of 1.5ºC. They use 1.5ºC as a marker because hitting it even once is sufficient to start risking AMOC collapse, with higher temperatures further increasing the chance and the mean time to collapse. As the article points out in section 3, we're already at 1.4ºC, and we're going to shoot well past that.

As for your, er, critical re-examination of scientific papers: You don't seem to be aware that atmospheric methane has a half-life of 10 years, with most methane production coming from the meat and fossil fuel industries that can be stopped.

The nature article's range of +3ºC to 7ºC assuming zero further emissions is bad enough without you needing to make stuff up.
