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.

Probably not as much, but I expect Europe will still use winter peaking plants for a good while.

In the context of a massive build-out of LNG export capacity, this implies a huge marketing effort by the fossil fuels industry to addict new users to it

The US is planning to increase its current LNG capacity by 5x, it's completely insane. The fossil fuel industry is too big and powerful for the government to have any chance to set any reasonable limits. Any talk of slightly slowing down LNG buildout is met with far-right hysteria.

They're successfully capping the size of the LNG buildout though.

This is basically a bet by the fossil fuels industry that as the US decarbonizes, they'll be able to export instead of leaving oil and gas in the ground.

Is that from fracking output?

Sure, but LNG is more expensive then pipeline gas and Europe has some reserves in Norway and gas pipelines to Northern Africa, Central Asia and somewhat the Middle East. That means as soon as Russian gas supply becomes zero, the US LNG supply to Europe is going to decrease.

There is also a lot of gas storage in the EU, which is meant mainly to work for the seasonal demand changes coming from heating with gas. Since wind is stronger in the North Sea region in winter, that means besides some non windy days, peaker plants will be used less and less. Grid sized battery storage and better grids are really being deployed relativly quickly, so that should fall as well. The big question is how quickly gas consumption is going to decline as most European countries focus more on shutting down coal power plants.
