Scorching Summer Heat

Climate Change Fingerprints in Europe’s Record Hot 2017 Summer 

September 27, 2017

Scientists with World Weather Attribution (WWA), using a combination of observed temperature data and climate models, have concluded that human-caused climate change made the record-breaking 2017 summer temperatures in the Euro-Mediterranean region at least 10 times more likely.

“We found clear evidence of human influence on this summer’s record warmth — both in the overall summer temperatures and in the heat wave dubbed Lucifer,” said Geert Jan van Oldenborgh, senior researcher at the Royal Netherlands Meteorological Institute (KNMI). “In many towns and cities across southern Europe, there is now a one in 10 chance of seeing a heat wave as hot as we saw during this past summer every summer,” van Oldenborgh added. “In the early 1900s, a summer like the one we just experienced would have been extremely rare.”

Hurricane Harvey Update

Currently, researchers with WWA and its partners are conducting an attribution analysis of the catastrophic heavy rains that accompanied Hurricane Harvey in August. The results of that study are expected later this year.
