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.

Golf courses use huge amounts of water. Streams get diverted to water them. The countryside dries up without its water, and then catches fire. It’s not good.

In southern Arizona they typically use reclaimed, non-potable water, at least. I wonder if they do that anywhere else?

Oftentimes they do not as it is quite expensive to make many kinds of "grey water" safe enough to be basically touched by golfers all the time. Being in the center of the desert with high water costs, it made sense in Arizona.

Regardless, keeping that much grass alive for such a small number of people to enjoy feels like a misalignment in priories of a local water authority to me. With the general trend towards water insecurities the world over I'm a bit upset with golf courses.
