The Northern Hemisphere experienced yet another phonograph record - breaking summer this twelvemonth , with a total of 396 location experience their highest ever temperatures , BBC Newsreports . Many of these chart - topping readings were recorded during theextreme heatwavethat engulfed Europe in June and July , when C of weather stations across France , Germany , and the UK saw the mercury climb to unprecedented levels . figure make by climate institute Berkeley Earth , which collect data from thousands of weather condition post worldwide , indicate that more than 30 internet site in the US also experienced their hottest day on record this year . Between May 1 and August 30 , emplacement across the Northern Hemisphere saw their highest ever temperature for a hold month some 1,200 times , with new all - time temperature records being set in 29 different countries . Berkeley Earth lead scientist Robert Rohde toldBBC Newsthat “ some home in Europe have histories of weather reflexion operate back more than 150 year , and yet still saw new all - clock time disk highs .
" As the Earth warms , it has become easier for conditions station to set new all - time record , " he added . " In the past , we would usually only see about 2 percent of atmospheric condition post record a new book high in any given year . But , recently , we sometimes see years , like 2019 , with 5 percent or more of the weather stations recording a unexampled all - time disc high . "
Worryingly , this datum is very much in save with a wide-eyed trend towards accelerated orbicular warming , aresult of human activity , with information evidence thatland temperature worldwide have risenby 1.5 ° nose candy ( 2.7 ° degree Fahrenheit ) in the preceding 250 years , and 0.9 ° C ( 1.6 ° degree Fahrenheit ) in the past 50 year . The four hottest years in recorded story have all come since 2015 , with 2016 being the strong of the lot – and with July 2019 being thehottest ever monthworldwide and last calendar month being thewarmest September on phonograph recording , it is almost certain that this class will stay the drift . Berkeley Earth ’s psychoanalysis has concluded that the contribution of solar activity to spherical heating is paltry , and that these originate temperatures are straightaway correlated with increase cold-blooded glasshouse gun emissions . consequently , a separate report into this summer ’s extreme European heatwave resolve thathuman activityenhanced temperatures by between 1.5 and 3 ° C ( 2.7 and 5.4 ° fluorine ) during the hot spell . Southern Hemisphere , it ’s over to you …
