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.

So the U.S. military has made the assessment that climate change is the single greatest threat to U.S. national security in the history if the U.S., and they've also simultaneously shrugged and said, nah man, we aren't going to do anything about it.. do I have that right?

Don't be silly. I'm sure the U.S. military has drawn up several contingency plans to massacre climate migrants.

there's a tremendous push to diversify the military's fuel use with EV stuff. they know what's coming.

sigh

We're in for an increasingly rough ride in the coming years...

If the rhetoric is that Santa delivers coal to bad kids then why are we subsidizing that industry?

[–] mosscap@slrpnk.net 9 points 7 months ago

Because the bad kids love coal, and they also run shit

the US military runs on fossil fuel, can't disempower the military

The bulk of their operations are logistics, which can be decarbonized. And military use isn't generally subsidized in the usual sense of that word.

Even the parts that still need fuel can use synthetic or bio, if there was ever an industry where costs don’t matter it’s the military. Besides, given how much dealing with fuel limit’s operations, any reductions in front end fuel use come with a directly proportional increase in capability.

military still has to buy it. i mean the infrastructure to produce oil has to be there and in good working order. subsidized by the public as required.

military will only decarbonize if it's a strategic advantage that they understand. i haven't heard any talk of them doing that except in out in the outer rim where it's difficult to ship fuel.

typical rug-pulling from the US's part. Otherwise how could they have become the first world superpower smh
