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.

Global Emissions Peak is a bit like the Year of the Linux Desktop. (We should also keep in mind that mismeasuring of emissions is rampant, as is outright cheating. So whatever year it is determined to be, in actuality it's probably going to be later.)

"Organization heavily involved in global shipping says we are on the right track for emissions control"

I dunno man...

They don't even say that. They say emissions will peak which is en par with other institutions.

X to doubt, but positive hope is better than no hope.

Just in, OpenAI released gpt 5 in partnership with shell

That'd be contingent on lots of things, such as random clowns not sabotaging the EPA and selling rights to Federal lands

The world is not just the USA...

You don't say.

Do you think the USA is incapable of a meaningful increase in global emissions? My original comment is implying the opposite

Maybe if you start heating your homes by burning car tires in your gardens. But otherwise, no. You are already so far behind the curve that economics really don't allow CO2 emission increases on a global significant level.

What if a country that holds half the world's data centers decides to walk out of every global climate accord and start powering those bad boys with fracking due to isolationist trade policies? Won't amount to zero and in less than a month we find out how that ship is changing its heading

[–] [email protected] 1 points 3 weeks ago (1 children)

Those data centers would soon be somewhere else due to... economics. And even if not, wouldn't be significant.

Why would a corporate entity move PP&E to a different country in light of the promise of increasingly favorable tax rates and the threat of tariffs? There's a reason why US and Ireland are havens. Those things are bolted down

Ok, bask in your american exceptionalism if you please.

Weird thing for you to say to someone basically parroting the IPCC's concerns.
