Climate ‘causing more and worse heat waves’

Researchers say there are now on average five times as many record-breaking hot months worldwide as we could expect without long-term global warming, with human activities responsible for four-fifths of them.
LONDON, 15 January – Climate change has already increased the incidence of dangerous heat waves five-fold, and 80% of them have been caused by man-made emissions. The last decade has been particularly affected.
These conclusions, by researchers at the Potsdam Institute for Climate Impact Research and the Complutense University of Madrid, look at the increasing incidence of record-breaking hot months since 1880. The last 40 years has seen a steady rise, but in the last decade the upward curve has been far greater. Even these disturbing figures do not include the recent record temperatures and disastrous fires in Australia.
