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.

I think this speaks more to water reusability than where you get the excess. If you can recycle 90% of the water, then you're water demand will be 10x less and likely easily sustained by rainfall.

Again, it's a cost analysis between reusing water, i.e. filtration, and desalination. Without numbers, it's only speculation.

Vegas has been emptying it's aquifers in less than a hundred years. It took millions to fill them.

Meanwhile, here we have a new golf course, in the middle of the desert! Cool, right?

Vegas is fucked, pretty much, that is no speculation. Other cities will need to make drastic changes in the upcoming decades, and I've seen shit all done because noone cares until it blows up in their faces.
