Check out this investigative podcast for some insight on the idea that focusing on renewable energy for air conditioning would be better. It's a pretty interesting topic.

It's always worth pointing out that 80% of humanities land use is purely for growing food for, and rearing, livestock. This only produces about 20% of humanities food.

There's plenty of room for people :) it's the 60 billion odd animals (especially the cows and other mammals!) that are the problem.

If people treated red meat and dairy like a luxury, (say, reduced consumption to once every two weeks) it would more than half humanities land use! It would also be cheaper, and better for their health so they'd live longer with a higher quality of love.

Reply to The antidiabetic drug metformin aids bacteria in hijacking vitamin B12 from the environment through RcdA (Jan 2023) by basmwklz

I was taking half a gram of extended release metformin daily, for longevity, for about a year, until I started feeling pins and needles (peripheral neuropathy) in my hands and feet. I then remembered I had read about metformin and B12 deficiency, and I immediately stopped it and started on a B12 supplement. Less than 2 weeks later, the pins and needles were gone.

Now I'm taking it again as my glucose levels went up (to 112 mg/dL), but with the B12 supplement, and I plan to measure my B12 in two months time.

green roofs are a good way forward too. We could go full on r/fuckcars but in the US or Canada, it might as well be asking for a miracle.

1/3 is pretty terrible.

How many excess heat deaths do air conditioners prevent?

Wouldn't a focus on renewable energy for air conditioning be more efficient and save more lives?

Admittedly air conditioning is worthless to the homeless population whereas trees benefit them. But that's another problem I think we need to actually address, getting people homes.

Edit:

it actually looks like air conditioning has barely superior performance when it comes to preventing heat deaths (35% rather than 33%) but this global figure is mostly caused by people not having access to air conditioning:

> This pattern holds true globally. A major 2021 research report in the Lancet estimated that, globally, access to air conditioning averted 195,000 heat-related deaths among people ages 65 and older in 2019

> The authors estimate that 1.7 million deaths globally in 2019 were linked to extreme heat or cold. Of those, 356,000 deaths were due to heat...

Eliminate cars. Everyone walks or cycles. Outlaw personal vehicles.

Industrial Hemp is a better idea. Grows faster, is a natural carbon filter, and it can be used to transition to the new green tech industry that is finding all kinds of useful ways to make stuff with hemp. Grow trees too in urban areas but grow hemp elsewhere.
