The last time Europe suffered from a drought as severe as the one it is experiencing in the summer of 2022 was before the first colonists settled in America.
Earth-observing satellites have been delivering a disconcerting stream of images to Europe's climate change researchers over the past months. Water levels in some of the continent's mightiest rivers including the Rhine, Danube and Po have dropped so low that the waterways had to close for traffic. Notoriously rainy countries, such as the U.K., have not seen a drop of rain in months, turning the landscape into a wildfire-prone tinderbox.
According to the European Union's environmental program Copernicus, the drought of 2022 may be the worst the continent has experienced in 500 years. At the peak of the dry spell in late August, 47% of the European territory suffered from a "soil moisture deficit" with 17% of the territory experiencing "vegetation stress due to the soil moisture deficit." The drought, Copernicus said, has affected many sectors including agriculture, transport and energy generation.
Some European countries, including Spain, Netherlands, France and the U.K., have instated water rationing measures like limits on daily water consumption and prohibitions on car washing.
The satellite data shows that only northern Scandinavia and the easternmost regions of Europe have escaped the drought. Copernicus program personnel wrote in a tweet that although "the data has not yet been analyzed and the summer is not yet over, the drought that is currently affecting Europe could possibly be the worst in 500 years."
If the analysis holds up, the summer of 2022 would be the driest since the the mega-drought of 1540, which apparently was caused by an 11-month-long rainless spell and a period of temperatures 9 to 13 degrees Fahrenheit (5 to 7 degrees Celsius) warmer than the European averages in the 20th century, according to Swiss historian Christian Pfister.
