One of the hottest countries on Earth is installing air conditioning outdoors and painting roads blue in a bid to keep cool.
Temperatures in summer now reach a sweltering 115°F (46°C) in Qatar, where the 2022 World Cup has already been moved to winter to avoid the searing heat.
Last year the tiny Gulf state began using air-conditioning in its football stadiums to keep fans and players cool.
But now giant coolers have been installed alongside pavements and in outdoor shopping malls so the temperatures are bearable for people going about their everyday lives.
And in Doha, the country’s capital, the Public Works Authority has painted the Abdullah Bin Jassim Street near one the city’s biggest souq markets the colour blue to reduce the temperature of the asphalt by 59-68°F degrees.
Roads in Qatar's capital, Doha, have been painted blue because the colour absorbs less heat than black tarmac so the surface remains cooler for longer
Cold air will be pumped into stadiums at the 2022 football World Cup, which will be held in the Gulf state, via large cooling nozzles linked up to chilled water
The blue roads help to lower the temperature because dark-coloured roads absorb the heat form the sun more than lighter ones, which reflect it.
The 18-month-long experiment is on a 650-foot (250m) stretch of road and uses a 0.003ins (1mm) thick blue coating with a special heat-reflecting pigment.
It also contains hollow ceramic microspheres which are designed to reflect infrared radiation.
Engineer Saad Al-Dosari said: 'The temperatures of dark asphalt is 20 degrees Celsius higher than the actual temperature because black attracts and radiates heat’.
Other cities around the world have also been conducting similar experiments to deal with the extreme heat.
This summer, Los Angeles painted its streets in a greyish-white coating which can be 23°F cooler than the black surface.

Doha (pictured) is so hot partly because it's on a peninsula in the Persian Gulf, in which surface water temperatures average around 90.3°F (32.4°C) – temperatures in the city can reach a sweltering 115°F (46°C)
