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.

It's worth noting that he also fired many of the staff who know how to ensure that they're actually safe, as well as the staff who would approve financing.

This is the Titan Submersible all over again, only on a devastatingly national level.

Let me elaborate. I think nuclear power is a great option, but not if you’ve removed real scientists and proper engineers. Trump doesn’t like scientists and engineers. Or anyone really, that doesn’t agree with him.

Nuclear power is the safest, cheapest and cleanest only because we have learned so many painful mistakes and that every new reactor is built with only safety in mind.

No discard all that so we make steam now!

Quite glad that America is far away from where I am.

great idea, nothing wrong will come from pressuring the nuclear power regulators. nuh uh.

It really depends on what these reactors are going to be used for. Are they going to be licensed to private corporations to power data centers, or are they going to provide power to citizens homes?

I guess the good news is when we have an iron man uprising it won't cause blackouts to humans to cut the power.

Beginning investments nuclear at this point when renewables so obviously to everyone in the know are beating them on all accounts is extremely on brand for someone as dumb as Trump

Nuclear is the single best technology humans have invented. A broken clock is right twice a day.

[–] endeavor@sopuli.xyz 1 points 5 hours ago

Nuclear is great and all but only when done safely.

diaper donny is saying "donny like fire, make more fire, donny no care where make fire, fire must be more since i say fire good"

This will end up with everyone burning down everything.

Being able to harness the power of atoms is cool, but directly harnessing the power of a star is arguably far cooler.

[–] mycelium_underground@lemmy.world 4 points 11 hours ago (3 children)

I'm confused as to what you think powers a star.

[–] Tetragrade@leminal.space 3 points 6 hours ago (1 children)

solar panels, duhh. why'd you think they were called that?

[–] endeavor@sopuli.xyz 1 points 5 hours ago

Best TIL I've had in a while.

[–] DeathsEmbrace@lemm.ee 2 points 11 hours ago

Well both of you are incorrect because a star is when gravity creates enough energy to cause nuclear fusion.

[–] PagPag@lemmy.world 1 points 11 hours ago

They are suggesting that pursuing fusion is better…

If there's one thing that you should compromise on when it comes to nuclear power it's definitely safety.

Hey good news everyone, instead of 40 years to build a new reactor, it’ll only take 39 years. What a relief. Good thing we didn’t fall for all that free sunlight and wind bullshit!

Hey, maybe nuclear plants can run on clean coal!

The one fucking thing you never want to cut corners on, and this clown is deregulating it. JFC.
