Europe ‘s temperatures is rising faster than expected, as climate change increases the number of days of extreme heat and reduces the number of days of extreme cold, a new study shows.
Temperatures in Europe have reached record highs this summer, exceeding 46.0 degrees Celsius in southern France, the number of hot summer days has tripled since 1950 and the summer has become hotter, according to the study.
At the same time, the number of winter days with severe cold has fallen by at least half, and winter is generally warmer. The new study shows that parts of Europe are warming faster than the climate models project, as the satellite image shows From Europe during July 25, 2019 the highest temperatures this summer.
“Even on this regional scale over Europe, we can see that these trends are much greater than we expect from natural fluctuations,” said Ruth Lorenz, climate scientist at the Swiss Federal Institute of Technology in Zurich, Switzerland, and lead author. Of the new study, which is considered a signal of climate change. ”
Extreme heat is dangerous because it affects the human body, which can lead to heat exhaustion or heat stroke. Scientists know that climate change is causing Europe to warm but they have often studied long-term changes in extreme temperatures.
The new study uses observational data from European meteorological stations from 1950-2018, then analyzed 1% of the highest extreme temperatures and highest humidity and the highest 1% cold days during that period and found that the number of extreme heat days in Europe It has tripled since 1950, while the number of bitter cold days has been reduced by two or three factors depending on the region.
Extremely hot days became hotter with an average of 2.3° C (4.14° F), while on extremely cold days the average temperature rose by 3.0° C (5.4° F) on average and individual regions across Europe experienced different temperature trends Radically, making it difficult to compare the average European temperature to the ends of certain plants.
However, more than 90% of the weather stations surveyed showed that the climate was warm – too high to be purely due to natural climate variability – according to the researchers, summer and winter in Europe will become hotter in the coming years as climate change accelerates, “Many people do not have air conditioning, for example, and that makes this very important,” said Lorenz.
