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.

Nations Are Getting Serious About Climate Action. Just Not Serious Enough. There’s a lot more work to do to keep global temperatures at relatively safe levels (www.nytimes.com)

If every single country were to follow through on its stated plans (a big if) then global greenhouse gas emissions would be 2 percent to 9 percent lower at the end of the decade than they are today.

But that would still put Earth on track to heat up roughly 2.5 to 2.9 degrees Celsius over preindustrial levels by the century’s end, the report found. With every fraction of a degree of warming, the risks from deadly heat waves, wildfires, droughts, storms and species extinctions increase significantly, scientists have said.

We are trying to save our species from extinction by carefully also trying to save the bank accounts of a few hundred people.

We are going to sacrifice our potential survival by coddling the finances of a wealthy few.

No wonder we don't see anything in the universe ... alien species are probably monitoring us, avoiding any kind of contact and just shaking their heads in awe at how stupid we all are.
