Nights in Las Vegas Are Becoming Dangerously Hot
(www.nytimes.com)
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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Would you say the same about places where it gets well below freezing in the winter?
Edit: Many older houses don't have AC in Vegas. They use evaporative cooling mostly.
It’s easier and more efficient to wrap yourself up with blankets and covers and use minimal heating (with decent home insulation) to warm yourself up than it is to cool down when you are too hot.
At an individual level sure, it's easy to throw on a blanket when it's cold. But at a household level, much more energy is used to heat homes.

yeah if you don't have heating (wood, pellets, gas, fossil, electric, whatever) you can't live in that climate. its, like, a thing.
but its way easier to heat a thing and keep it warm than cool a thing.
huh. I was just looking at air conditioners being really inefficient and it being really hard to keep a thing cool passively because all the stuff we do/have makes heat nowadays.
It's easy to passively cool things, as long as you're okay getting them wet :)
me? yes. my living space? less.
On the other hand, ACs are heat pumps, which are generally efficient for transferring heat energy (both to warm and cool)
The laws of thermodynamics disagree
