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.

Never understood the freakout over nuclear ..... when you measure up the long term statistics

Gas/Oil/Coal have killed more people over the past 100 years than nuclear ever did (even if you threw in the bombing deaths in Japan in WWII)

The deaths caused by gas/oil/coal are just not as dramatic ... all those people died from global pollution, poisoning, early death, shortened lives, lung problems, bad health ... and all by the millions

The general populace isn’t looking at statistics, they’re looking at scary news stories

The public is never good at stats, or complex ideas that cannot be converted into a good old fashioned sound bite.

Maths hardly ever change major policy by themselves. Often it’s only an accident of political necessity when policy is backed by statistics or science

The general public is one thing, but that doesn't excuse the positions of activist organizations like Greenpeace that should've been better-informed.

Often, but not as a rule, progressive organizations age badly
