The forecasters say the change is a clear sign of climate change. 

A heatwave is described as 14 consecutive days with an average temperature above 30 degrees and nights of above 20. 

A heatwave in major cities was expected every 4 years on average, now its every 2. 

The forecasters say they expect that to continue. 

Weather records from all three countries date from the mid to late 1800s – except for Austria, which has accurate numbers from 1767.
