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.

How about to each his or her or their own? Like let Texas be the oil smeared radioactive smelling shithole it wants to be?

That the US is going to fall further behind China in green energy technology.

As someone currently on extended vacation, enjoying several national parks, I would suspect national parks will be gutted for natural resources.

One thing that I’m hopefully about is that solar is so cheap now so that will continue to roll out like crazy unless someone places huge tariffs on imported goods… oh shit. I just found out about the massive tariffs that fascist is wanting to put in place.

Solar and wind are only relatively cheap if you don't need to buffer. Unfortunately, you do. And electricity production is only a fraction of primary energy use. Concrete, steel, glass, fertilizer, chemistry, diesel and bunker fuel for shipping and mining. Can't make new renewable infrastructure without fossil extraction.

[–] futatorius@lemm.ee 2 points 2 hours ago

About half of the fuel used in shipping is to move fossil fuel from one place to another.

With current battery and hydro storage prices, their cheaper than natural gas with with the cost of the buffer, and absurdly cheap for any industrial application that doesn’t.

Also there are bulk industrial processes to make steel, concrete, fertilizer, and glass with little to no carbon emissions, they just require more electricity and so aren’t cost effective if your electricity comes from fossil fuels, hence why most such plants only started construction once the cost for electricity in general dropped below the cost for fossil electricity.

Moreover while mining and shipping are only starting decarbonization, the required fossil fuel extraction is already far, far smaller than what’s continually required to run the generation they are replacing, and that’s only going to continue to drop as more and more primary energy is electrified with renewables.

The guy literally loves fellating.

Always wanting to drill everywhere.

Assuming there is more oil to drill for...

[–] disguy_ovahea@lemmy.world 3 points 12 hours ago

There’s plenty under the 28M acre Alaskan wildlife refuge that Biden secured this term. I wouldn’t be surprised if Trump granted drilling rights in his first year.

There's more oil. Peak oil is about easy to get oil, not actually running out. We'll spend whatever it takes to keep this machine turning.

He can't make the unextractable extractable. Nor can he make consumption stop. In terms of the Keeling curve, the impact is exactly zero.
