We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

What a surprise! Who would have thought hat having thousands of gasoline powered radiators driving around 24/7 would generate heat in a city.

Obligatory !fuckcars@lemmy.world

Between this and the large swathes of asphalt for driving and parking, of course every city is boiling hot.

Stop routing highways through cities and start making bike lanes, dammit!

And add tree cover!

Heat sources contribute to rising temperatures. Weird.

Thousands of internal combustion engines. Go figure!

[–] innermachine@lemmy.world 1 points 1 week ago

I ride motorcycles unless it's snowing or free ing rain out as a cheap way to reduce carbon footprint. It's incredible how much warmer it is when driving into cities, and as you pass cars you can feel the heat coming out from underneath them. I have tried to explain to climate change bay Sayers that just the heat we throw out of vehicles and ac units and coming off black roads etc adds to the global temp nevermind the emissions!

Look I get the point people are making about cars but the basics of this is just stupid. Things that generate heat contribute to the overall temperature?!

Next they're gonna tell me the widespread use of air conditioning heat pumps also generates heat island effects!!!

[–] Telodzrum@lemmy.world 5 points 1 week ago (1 children)

Yeah, cities have been heat islands for millennia. This is just another thing on the pile. Plant trees, put solar on roofs, use waste heat for building heat (in cities is basically the only place this makes sense).

The normalization of car-based infrastructure is one of the biggest fuck-ups of civilization. The negative effects just keep on going

[–] Kkk2237pl@szmer.info 2 points 1 week ago

We dont even realize how much impact it has.

Lets take China, they only switched from ice to evs, and there are so quiet. What would you achieve if you wont have car infrastructure at this scale

Fork found in kitchen type findings.

In other news, sky is blue. More at 5...

[–] rwrwefwef@sh.itjust.works 3 points 1 week ago

Always did?

What is the point of a study that confirms what is already known? Paved streets are an even bigger contributor.

[–] spitfire@lemmy.world 2 points 1 week ago

How did they figure that one out?

[–] obinice@lemmy.world 2 points 1 week ago

haha, I was just thinking about how this is very noticeable here in Manchester, then saw the URL!
