Officials in Los Angeles have taken a radical approach to lower temperatures in the city.


California is no stranger to crippling heatwaves and even fatal wildfires caused by these spikes in temperature.

So, while the world looks to climate change and potential solutions to the world-wide issue (see what Origin is doing hereofficials in LA have kicked off their own battle against the elements by painting local streets white. That's right, white asphalt.

In an article for Australian Popular Science it said the road make-overs were part of Mayor Eric Garcetti's attempt to "cut the average temperature in LA by 3°F over the next two decades". When you consider that a temperature difference of 1°F is the equivalent of a temperature difference 0.556°C - the shift may only be a small one, but it's certainly in the right direction.

So what is this magical "road paint" called: CoolSeal  and it's created by GuardTop. The company says on it's product specification sheet that it's "commitment to sustainability has guided the development of CoolSeal" which it describes as "an ultra-high performance asphalt-based sealcoat that achieves lower surface temperatures with its lighter coloured surface and higher reflectivity". It notes that the product would be ideal for "school districts, parking lots and LEED-eligible building projects".

Watch this space. No, literally watch it being transformed into a white road ...
