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.

Yeah it's crazy. It's almost like plopping down a big ass city in the middle of the fucking desert was a terrible idea. And then continuing to run it even while the climate dials up that latitude from char to incinerate.

Las Vegas grew out of being a train stop for water. Yes, water.

It was a necessity. Example: All the towns across the plains were spaced apart almost equidistant 5-7 miles as that was far each train could go before the locomotive needed water refills. Can't imagine how annoying it would be to ride those early trains.

It also begs the question, are all those towns, as they ghost away, necessary? They served a purpose once in the 1800s. People bemoan the loss of small town America, but a lot of it was literally to fuel the primitive railroads. Maybe some of them no longer have a purpose.

Back on topic, Las Vegas certainly doesn't.

What purpose does any city serve?

The largest water reservoir in the US is a few miles away. A large air force base was built on the, then, out skirts of town, the nuclear testing site, and the magnesium plant in nearby Henderson. All of which helped the US in WWII. That's why Las Vegas isn't a ghost town. It's much more than gambling and debauchery. If that's all it took, then why isn't Pahrump (where prostitution is legal) a big city? What happened to Reno, which used to be the place to go party?

I think Lemmy users are incredibly ignorant of Las Vegas and should get a little bit of reading in before trashing my home town.

You also may want to let the 2 million plus residents know their city is not necessary.
