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.

“Higher-pressure showers were definitely shorter,” said Walker. “The open question is really: why is it shorter? Is it that it just rinses products off quicker? Is it that it’s more satisfying, and you feel clean quicker?”

Or is it that it's less comfortable and relaxing, and people just want to get it over with? I would not automatically assume the shortness is due to a superior experience.

Definitely the former for me. Low pressure showers suck. It's a pretty common thing to hate.

I absolutely hate low-pressure showers. I have to take longer because nothing rinses quickly.

I live in a house that has water pressure below 30psi (and doesn't seem like it can even keep up with that), I definitely take longer because it doesn't rinse my hair/scalp out properly. And it is unsatisfying.

Then again, I also take less showers than I should because of that (though I also have a medical thing where I do not visibly sweat even in extreme conditions so things like pit stains are not a thing) so I use much less water overall. Probably gross but I am a shut-in.

If you're asserting that high-pressure is uncomfortable, the user should be able to just... set it to a lower pressure before (or after) they get in. Though if you mean just-get-it-done mentality I'd say that's not a bad thing so long as they are in the shower long enough to get clean, seems like an optimal situation (for most people at least) to me.
