How to combat extreme heat in urban areas | Future Earth | BBC News

The climate crisis is making our cities hotter, posing a significant health threat to those living in urban areas.

The BBC’s Carl Nasman explores the specific challenges cities face as temperatures rise and looks at the solutions already in action, including reflective surfaces and increasing greenery around our concrete jungles.

This is episode one of Future Earth, a series exploring today’s most important developments in climate science and sustainability.

Why don't you use Celcius for measuring the temperature

Literally trees. I live in the mountains and there’s a patch of trees growing over a large section of my road. When I pass that spot on my side by side it could be 100f out and 30° cooler under that canopy. You almost get the chills.
Now I’ve planted 58 trees on my property.
I’ll get lower temps and some nuts and fruits.
My progeny will too.

The best solution is not letting it get to that point. That being said: Trees, trees everywhere, walkable cities.

Using Fahrenheit sigh, is it really that hard to add Celsius in brackets or the closed captions?

[yes]

There were many protests in Poland against removing trees and paving public spaces in cities. Trees are a part of the solution, but also using too much hard surfaces like concrete will increase the temperature and decrease water retention, which is bad if you have flash floods on the rise. There should be both trees and unpaved green areas wherever it's possible.

Wonderful documentary. We need clever solutions and going on investigaring new ways of cooling our cities and public spaces.

We can't stand this heat here in Sao Paulo Brazil 😢

How about building cooling towers in community buildings aka wind catchers, like the one's in other countries. Reduce your electricity consumption for a/c. Put them in schools or other community buildings for people to cool off if the grid goes down. Look into ancient windcatcher cooling technology. Also, there is the Persian ice house, or how to make ice in the desert

Would it be possible to provide transcripts of these kinds of independent study?

[juancarlosdominguez]

excellent and motivating first show! cheers from Havana Cuba

[SJknowledge]

It's becoming to hot day by day 🔥

[AryanIndustrial]

I'm working towards to mitigate this heatwave issues. ❤😊

[mdziauddin]

It’s very great news.I think that it’s a good documentary and a lot of pepole helpfully in neture

[Censortubes]

Stop building them? Or we acting like the concrete etc isn't raising the temps in city's? When it's been proven many of times.

[TylerChristoher]

Living in Central City Phoenix right now. The hottest city in America. As soon as I can get enough money and make a plan I'm out of here. There's some nice things about this city. But one of my favorite passions is stream restoration and fishing. And not having any rain for so many years is depressing. It's just too hot for the AC in my car and apartment

[yoqjlxi]

It's really motivatng, and we need to keep finding better way to cool our cities.

[alicewood]

I wonder if there's a way to make asphalt a lighter color?

[olegcmd]

we must stand up together to preserve the trees, its our life and we lives on this planet so its our responsible to keep green forever.

[LaziaMedia]

Yeah trees are the best solution to keep temperature down. And I take apart in geography classes

[hmqotkk]

amazing documentary. lots of information, simple and effective solutions.
