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.

Good. Stop using our groundwater to grow cattle food for other countries, assholes.

There could have been less disruptive ways of doing that though.

Obviously, it would have been better if these farmers had never started growing alfalfa rather than plants more adapted to dryness.

The farmers themselves could've taken that initiative, too.

It sucks to suck … water indiscriminately from finite aquifers to produce food to ship across the globe to feed beef cattle.

TIL the us exports alfalfa to china? What the fuck man why would you do that that sounds fucking insane man

[–] futatorius@lemm.ee 5 points 3 days ago (1 children)

Yes, and they're growing it in the Central Valley, using water piped in from elsewhere at great expense (though to taxpayers and other water users, not to the farmers).

[–] casmael@lemm.ee 1 points 3 days ago

This sounds so monumentally stupid I have no advice other than has anyone tried you know, not doing that? Alfalfa? Really? fuck my life bro
