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.

Now we just need the septuagenarians and octogenarians to step down from power and retire.

I don't care how old they are so long as they do the right thing. Being a good ancestor is a perfectly fine motivation.

The current group of old people in power are not doing the right things though. They either try to discredit the idea of climate change altogether, minimize its effects, pay lip service to it, or ignore it entirely.

Vote 'em all out.

I think about encoding that in my model - e.g. assume a 50 year time-lag between current science influencing young people in formative years, and such people gaining power with a gerontocracy, what does that imply for solving such issues (a fuzzy-control problem - bearing in mind cumulative emissions, ocean layers, and ice-melt -> answer not good ... ).
Actually we knew most of this science 30 years ago, and some politicians try hard, problem is other distractions.
