The Economist with a cool (ha) article on innovation in air conditioning. TL;DR: - Avg temperature already up 1.2°C from pre-industrial baseline, on track to +2°C by mid-century. - AC units to triple by mid-century. - Evidence exists for heat-related mortality avoidance thanks to AC. - AC contributes more CO2 emissions than the airline industry. - Cooling becomes *more* energy intensive per ° as air temperature rises. - Decarbonizing electricity would help, but AC lifespan is typically 20 years, so the energy efficiency of units sold today will impact emissions through mid-century. - AC design currently does two things: cool the air and remove the condensed humidity from around the coils to avoid damage. - Research shows at least 40% improved efficiency by separating those two functions: push humid air through a lattice or membrane that captures water first, then cool the air. https://www.economist.com/science-and-technology/2024/09/04/new-tech-can-make-air-conditioning-less-harmful-to-the-planet

If I’m getting this right, Thoman ACs do more harm than good?

Individually no, but collectively yes. Most people who need AC don’t have it, and yet they subsidize those who do (by paying indirectly for climate externalities, i.e., the local impacts of global warming from GHG emissions)

Okay i think im getting it But by "indirectly paying for climate externalities"? Are you referring to the increased costs of healthcare, infrastructure, and other services related to climate change?

Yes, plus local droughts, extreme weather events, job loss, water shortages, diseases, etc. Essentially all the first and second order impacts of climate change. The GHG emissions are disproportionately caused by a few (top five countries out of ~200 account for ~50% of emissions) but the costs are borne by everyone

Really crazy that a small group of countries is responsible for such a large proportion of emissions with the impacts of climate change felt globally lol And what about the idea of "polluter pays" ……. do you think there's a case for making those who contribute most to emissions take on more responsibility for addressing the problems they're causing or nah

There’s an easy and equitable fix for that: https://warpcast.com/aviationdoctor.eth/0x93718193

That makes total sense. So, basically a carbon tax You’ve been posting about this for quite sometime, but then i checked your bio and understood How were you able to grow on here by just posting mainly about your irl job and passions (Could honestly take one or two from your books)

Truth is, I was early and benefitted from auto follows for a while I’m not that interesting — I tend to cast about niche stuff

As a counterpoint: I find you one of the (if not the) most consistently interesting casters, both on topics and depth/perspective on the given topic.

Thank you for your kind words! I think it only signals that you and I have common interests, but it doesn’t rule out them being niche 😄

Sure, it's subjective. But also, impact of climate change on aviation is niche, but climate change in itself isn't. And it's not just about topics or agreeing, I noticed you tend to bring depth and nuance to the conversation, relevant data and sources, ...
