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.

oil-exporting countries’ willingness to acknowledge that the era of fossil fuels must come to an end

it underscored that talk is cheap, and they're confident that even if they say it, nothing will come of it

It took nearly 30 years for them to even say it, even thou everybody knew it. Talk is cheap, but not that cheap. This is going to be used in many countries to push for faster anti fossil fuel action.

I certainly hope so.

It doesn't really seem like progress in my mind - fossil fuel producers are just switching strategy from denial to "menthol is better for you than regular cigarettes." They aren't cutting production, and the work remains for us to regulate their shitty product.

Russia the second largest oil producer is currently sanctioned rather heavily making it harder for them to buy high end oil equipment.

The Middle East sees Yemen attacking ships including tankers nowadays. The Middle East has a lot of oil and that might be cut off.

At the same time we know oil is bad and we have great alternatives mainly in transport with trains, bicycles and so forth and also worse ones like EVs. So if we see extraordinarily high oil prices, we can realistically reduce consumption. That is a big change.

Still too little too late
