European heatwaves 'have doubled'By Paul Rincon
Science reporter, BBC News
The duration of heatwaves in Western Europe has doubled since
1880, a study has shown.
The authors of the research also discovered that the frequency
of extremely hot days has nearly tripled in the past century.
The study shows that many previous assessments of daily summer
temperature change underestimated heatwaves in Western Europe
by about 30%.
The research appears in the Journal of Geophysical Research -
Atmospheres.
The team found that heatwaves lasted an average of three days
now, with some lasting up to 13 days. This compares with an
average of about 1.5 days in 1880.
