As relentless heat wave has followed relentless heat wave across the United States this summer, conversations have increasingly turned to the role of global warming in extreme weather events. A new study solidifies the link.
Before 1980, excessively hot summers were practically non-existent. More recently, found a new study, summers that averaged 3.3 degrees Fahrenheit hotter than normal have become common – covering about 10 percent of land area around the globe each year – up from an average of just a few tenths of a percent in the 1950s, 60s, and 70s. In some recent years, super-hot summers have struck as much as 20 percent of the Northern Hemisphere.
Statistically, the pattern is too extreme to be considered a result of chance, found a new study, which pointed a finger directly at global warming as the underlying cause of the recent spike in extra-hot summers.
With projected warming over the next 50 years, the study predicted that summers averaging 5.5 Fahrenheit above normal will happen regularly. In a decade, nearly 17 percent of the globe will likely be experiencing scorching summers each year.
