According to a new study in Nature, the Northern Hemisphere has experienced considerably larger variations in precipitation during the past twelve centuries than in the twentieth century. Researchers from Sweden, Germany, and Switzerland have found that climate models overestimated the increase in wet and dry extremes as temperatures increased during the twentieth century. The new results will enable us to improve the accuracy of climate models and to better predict future precipitation changes.
Predictions of unprecedented rainfall extremes in the 20th century driven by global warming turned out wrong, a study said Wednesday, casting doubt on methods used to project future trends. A massive trawl of Northern Hemisphere rainfall data for the last 1,200 years revealed there had been more dramatic wet-dry weather extremes in earlier, cooler centuries before humans set off fossil fuel-driven global warming.
This is problematic, said a study in the journal Nature, as the…
