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.

It ain't how much you've got, it's how you use it.

Reminds me of another India beat-the-heat tech that I read was widespread there for centuries.

Those who've ever been in a root cellar or basement are excused. You make a hole in the ground, then go down in it. Underground temperatures world-wide hover around 50-60 degrees all year long.

Make a BIG hole in the ground, and build stairs that people can use to go down into it. Heat rises, so not a problem.

Cool article, thanks. Your comment also reminds me of this video - an immigrant dug a huge series of caverns in California, grew fruit trees in them, and it all started because he was a day laborer and was trying to get out of the heat.

(I recommend Kirsten Dirksen's channel, she sees quite a few interesting homes.)

Neat video about a remarkable home. Starting in 1906! 10 acres! ... inspired by the catacombs of Rome ... subterranean fish pond ... I'm not much of a tourist but it'd be great to see this, wow.

I wanted to try that in my home town in the tropics but I observed that anything underground fills with water immediately and even overground structures end up suffering water damage that's very resistant to most measures I've seen.

Still wondering what's best for those kind of climates.

I tried digging a hole in my pantry, but the guy from 405 was all like "my ceiling, my ceiling!"

Need some fans to churn the air in that hole or it will become a carbon dioxide trap.
