A mass extinction event wiped out around 90% of life. What followed has long puzzled scientists: The planet became lethally hot for 5 million years. Researchers say they have figured out why using a vast trove of fossils.

The paper is here

    Yeah humans are great at learning from their mistakes and would never ever repeat the same mistakes over and over and over.

      No of course not, we’ll make new cleverer mistakes that rhyme with the old ones and might even be the exact same ones just differently packaged…. But not like the SAME SAME ones

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.
