Climate - truthful information about climate, related activism and politics.

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.

Can climate science attribute economic damage to major polluters? (www.newscientist.com)

Climate researchers argue their science has advanced enough to directly link emissions from particular companies to damages from specific extreme weather events

“Many of the barriers to these cases are not scientific but political or legal,”

There is no guarantee a court would accept the details of this methodology either, says Myles Allen at the University of Oxford, who proposed more than 20 years ago that climate science may eventually make it possible to sue emitters for damages. “Will the courts accept evidence of a statistical link between annual mean temperature and the impacts of extreme heat, as presented in this study, when it comes to attributing causes of the harm done by a specific heatwave? Some may.”

I’m really looking forward to the international tribunal on crimes against planet earth.

Why not try stopping the polluters before the extreme weather events?

Well, the extreme weather events are already taking place. The point for me is that we should stop them before they do more damage. And they should pay to mitigate the damage they already caused.
