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.

Since Texas power sources are majority fossil fuel, this creates a fun death spiral.

Extreme heat => more power use => more fossil fuel emissions => more extreme weather => more power use => more fossil fuel emissions => more extreme weather => ๐Ÿ’€

Fun fact barely no one lived in Texas before air conditioning was a thing. Gigantic sprawling cities in the middle of the desert are only possible because of oil

There is a interesting map that shows that: Mean center of population of the united states

On this map we can see that center of population in the United States moved almost on a straight line from east to west.

It's only around 1940-1950 that the center of population started to move south. Coincidentally this is also the period where home air conditioning started to become accessible to the general public.

that's very interesting, thanks. I keep in mind there are likely dozens of biases and other reasons contributing to this change, but air conditioning is realistically a significant part of it

I live in a desert as well and this has been on my mind a lot lately. Planning to move as soon as I have the means. Until then we just have to try our best to use as little as we can without living in complete misery.

I can't understand how some Texas cities are attracting so many new residents right now. It's just insanity to me.
