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.

Waiting for the nuclear gang to drop in and tell us that all windmills and solar panels should be dismantled in favor of clean nuclear power plants and that Germany should never have abandoned the atom.

What if they advocate for nuclear power and say leave the solar panels up?

Then they can tell us where the budget comes from then fail to explain why it's worth five times the price of other renewables with grid storage.

Germany shut down it's reactors as they reached end of life. It isn't economical to build new reactors.

Nuclear has always been a military and strategic concern. Better than importing fossil fuels from potential bad actors during the cold war and you get some MAD weapons along with it.

If you support the weapons proliferation, you support nuclear. You believe in the cold war stand off and think it's valuable. If you don't, want nuclear war, you have to count that as another negative.

Arguing it's an efficient way to produce electricity, even if it's replacing fossil fuels, is disingenuous.

Pick two out of powerful, efficient, safe. That's nuclear power.

Nuclear reactors do not need to use weapons-grade materials or byproducts.

They don't use it but they can produce it.

Only one type of reactor, the old uranium design, produces anything weapons grade (Which then requires an additional step to purify). Don't use that reactor design.

[–] Ross_audio@lemmy.world 0 points 3 days ago (1 children)

Agreed.

Also, don't waste money on experimenting with the others. Just build renewables and grid storage.

[–] infinitesunrise@slrpnk.net 1 points 2 days ago

Low-weaponization nuclear reactors already exist, industrial-scale grid storage doesn't, but yes the answer to this dispute would be much more clear if it did!
