From Sweden to Sierra Leone, cities are turning the climate crisis into a chance for better, healthier living, reports Martin Wright
Sometimes a couple of cans of white paint can make all the difference. Thats the lesson from Ahmedabad, in the Indian state of Gujarat. A tidy white roof shows 80 per cent of the suns heat, compared to just 20 per cent for a (normal) grey one..
Captivating as that sounds, the songs been earworming through my head for an extremely different reason. Ive read predictions of how summertimes in the city could get a lot hotter, and not in a great way, as the climate draws out of control (the UK got a taste of that recently as it baked in a heatwave)..
In Londons Hammersmith, regrowth expert Groundwork has actually worked with the district council to spongify the environment of 3 real estate estates. Hint green roofs for apartment or condo blocks, renaturalised surfaces in place of concrete, and brand-new growing beds. Some 20 homeowners have actually been employed as green team students, while retrofitting energy-saving (and money-saving) packages in homes has actually helped win their assistance.
Initiatives like these will not cure cities of environment change on their own, of course. And on the other hand, they make summer in the city a sweeter season entirely.

What captured my eye though, was not the familiar cautions of what life in a 50-degree city might be like (borderline difficult, basically). Rather, I was struck by the sheer variety of actions that cities across the world are starting to put in place to cool the streets. Responses that dont simply decline the urban thermostat, however that make life sweeter for their individuals in the here and now.
” Hot town! Summer in the city …!”.
Rather, I was struck by the sheer range of responses that cities across the world are beginning to put in location to cool the streets. Spurred on by the UN Environment Programmes Cool Coalition, other cities are capturing the chill. Dubbed the countrys rainiest city, it has wrestled for years with too much water in the incorrect places. Initiatives like these will not treat cities of environment modification on their own, of course. And on the other hand, they make summer season in the city a sweeter season altogether.
Winning regional hearts and minds is crucial to a scheme in the Swedish city of Gothenburg, too. Dubbed the countrys rainiest city, it has battled for several years with too much water in the incorrect places. Now its turning an issue into something playful, with a couple of rain playgrounds, including one at a regional school. This makes a feature of a downpour, channelling it through the school backyard, sending it sploshing into pools, before gradually leaking away into a marshland of puddles and stepping stones. It slows the circulation to manageable percentages and, simply as importantly, the kids love it.
On the other hand Athens, the European city most threatened by the climate crisis, is regreening its hills, which were well known for their forests in classical times; restoring wastelands as nature parks; and installing fountains to cool the air in the citys popular squares. Temperature Levels in Omonia Square, below the Acropolis, have already fallen by 4 degrees C as an outcome.
As soon as infamous as Colombias cocaine capital, its future track record could rest on a series of creative actions to the climate crisis. And its had a recovery impact on communities, too, with individuals who had actually suffered years of violence coming together to be trained as city gardeners.

In cooler, cloudier Britain, the climate crisis implies floods as much as heat. The secret here is to absorb water as it falls, so absorbing the force of any flood and slowing its rate, by making our city landscapes less like a smooth sheet of concrete and more like a sponge..
So as part of its heat action plan, developed with the US-based Natural Resources Defense Council, the city assisted residents in low-income areas to tidy and coat their roofings with reflective paint, and the outcomes speak for themselves..
This easy solution is matched with more sophisticated ones, such as customised WhatsApp cautions set off when a heatwave looms.
” Since we painted your home,” stated one, “we dont feel that hot any more. We feel relaxed, your house feels cool. Our electrical power expenses are likewise decreased.”.

Spurred on by the UN Environment Programmes Cool Coalition, other cities are catching the chill. Sierra Leones enthusiastic effort to increase vegetation by 50 per cent. Milan is targeting 3m new trees as part of its 2030 goal of cutting temperature levels by 2 degrees C. And Melbournes putting metropolitan reforestation at the heart of its strategies to decrease the soaring demand for energy-guzzling air conditioners in Australia.
