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.

“Emerging”- what does that mean? Whats the timeline on them? The failure rate? The cost at the scale needed? I mean if you’re gonna complain about nuclear being more expensive then the batteries need to be cheaper necessarily. Also what materials are they made out of?

I suppose you know don't about the superbattery projects already implemented, e.g. the one in Australia and its huge benefits to their grid?

About sodium based batteries which have become commercially viable in recent years?

And because of the implication also that nuclear reactors produce extreme waste of building materials (e.g. Greifswald, ran for 26 years, dismantling in operation since 35 years and projected to last till 2040 at least, because higher contamination than estimated) and mining for them is at least as bad as for Lithium?

If not ask the search engine/ai of your choice.

This one?

If so it would supply just New South Wales for only 20 minutes. Hardly seems to be on the verge of solving grid scale storage.

Now to the word "emerging"

This was built entirely in 16 months, from groundbreaking to connection to the grid. For the cost of a single nuclear reactor you can build 30 of these. And opposed to nuclear technology batteries are still making remarkable progress in their affordability.

Edit: Btw the battery also uses below 0,5% of the area of a usual nuclear plant.
