This article discusses how humans have caused climate change, making heat waves twice as likely as before.
Climate change resulting from human activities made the current Europe-wide heatwave more than twice as likely to occur, say scientists
Researchers compared the current high temperatures with historical records from seven weather stations, in different parts of Europe.
Their preliminary report found that the “signal of climate change is unambiguous,” in this summer’s heat.
They also say the scale of the heatwave in the Arctic is unprecedented.
