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.

UK Prime Minister Keir Starmer has written an op-ed piece in The Sun promising "I will not sacrifice Great British industry to the drum-banging, finger-wagging Net Zero extremists"

Which means he's willing to sacrifice all the industry to appease the fossil fuels industry.

Isn't it less of a game of a chicken and closer to a global Prisoners Dilemma? The best option for everyone is for everyone to do the thing, the best option for individuals is to not do the thing but the worst thing for everyone is to not do the thing?

Yes. Chicken is an example of a prisoner’s dilemma, though with the key difference that it plays out in real time instead of a single instant.

Tragedy of the commons is usually the result of a large group game of chicken/PD.

I don't think I've ever thought of chicken that way... Questioning if I even understand it at all 😂

But yes, you're right, the whole thing requires everyone to contribute equally for it all to work properly but, since everyone can momentarily benefit more by not, and politics is painfully shortsighted, they won't do the right thing.
