Statistics show that heat waves like this are becoming more frequent due to climate change, and are something that Europeans are likely going to have to get used to. “Monthly heat records all over the globe occur five times as often today as they would in a stable climate.” Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research told AP.

"This increase in heat extremes is just as predicted by climate science as a consequence of global warming caused by the increasing greenhouse gases from burning coal, oil and gas.”

The controlling force of the weather is the Jet Stream, a fast-flowing wind-river that loops around the northern hemisphere at a height of 10 kilometres. The Jet Stream's behavior is linked to Arctic ice cover, which has decreased in recent years.

"The forecast from climate change models and the actuality of the last few years has shown a change to this Jet Stream," Al Jazeera's Rob McElwee said.

"It now has much greater loops, draped over North America and Eurasia, whereas a tighter, straighter flow used to be the norm. A looped Jet Stream induces long-lasting, low-pressure circulations and high-pressure domes," he added. 

Such a set-up has drawn air up from North Africa, in a southerly breeze, to cover Western Europe. Over the coming days the hot weather will be increasingly confined to France, Italy and Spain as a cooler breeze flows across northern and central Europe.

Dim Coumou, a scientist at the Free University of Amsterdam, also said that melting Arctic sea ice is affecting atmospheric circulation, which in turn makes extreme weather more likely.

“Data analysis shows that the normally eastward travelling summer circulation of the Northern Hemisphere mid-latitudes has slowed down, including the Jet Stream,” he said. “This favors the buildup of hot and dry conditions over the continent, sometimes turning a few sunny days into dangerous heat waves.”

Heatwaves can become really dangerous when they take place in early summer. Europe's 2003 heatwave resulted in the deaths of an estimated 70,000 people, let's hope that this year people are better prepared for the incoming inferno.
