CNN video(CNN) - The scorching heat wave that broke records across Europe last month was made more likely, more intense and up to three degrees Celsius hotter by climate change, a study has found.
The UK, Germany, Belgium and the Netherlands all recorded their highest temperatures ever in the July heat wave, with the mercury topping 40 degrees in much of mainland Europe.
The July event was the second record-smashing heat wave in two months, with a similar one bringing 45.9 degree temperatures to France and causing wildfires in Spain in June.
Less than 5% of all European households have been air-conditioned, and public transport can grind to a halt in intense heat.
A group of European scientists previously concluded that the June heat wave was made at least five times more likely because of climate change -- and perhaps 100 times more likely.
