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.

About 40 million people and 5.5 million acres of cropland depend on the Colorado for drinking water and irrigation, but its flow has gradually diminished over the past two decades as the climate becomes warmer and more arid across the West. Now the arcane system of water rights governing the river entitles each state and Mexico to far more water than is actually available. The rules prioritize the longest-established uses of water, in many cases dating to the 1850s and 1860s.

Not really discussed much: the water mostly goes to food for cows and cars, not people

Climate Town has a really good video on how we got into this mess in the first place, and it's wildly messed up even before you factor in climate-crisis-related issues. https://www.youtube.com/watch?v=XusyNT_k-1c

I took this pic of Hoover Dam in March. The white stained rock indicates the highest water level. The last time the water level was high enough to open the spillway tunnels was in 1983.
