Hotter Summers Beginning in 20 Years, says Stanford Climate Scientists

June 10, 2011

A Stanford University research team has projected that the tropics and much of the Northern Hemisphere are likely to have irreversible rise in summer temperatures within the next 20 to 60 years, if atmospheric greenhouse gas concentrations continue to increase.

According to the study's lead author Noah Diffenbaugh, "large areas of the globe are likely to warm up so quickly that, by the middle of this century, even the coolest summers will be hotter than the hottest summers of the past 50 years." The authors analyzed more than 50 climate model experiments including computer simulations of the 21st and 20th century and revealed that many parts of the planet could experience a permanent spike in seasonal temperatures within 60 years.

This dramatic shift in seasonal temperatures could have severe consequences for human health, agricultural production and ecosystem productivity.
