Will Very Hot Summers become a Permanent Fixture?
Jun 8, 2011; 10:02 AM ET
Intense summer heat could become a permanent fixture in the near future......
Researchers from Stanford University analyzed more than 50 climate model experiments including computer simulations of the 21st century when global greenhouse gas concentrations are expected to increase, and simulations of the 20th century that accurately "predicted" the Earth's climate during the last 50 years. The analysis revealed that many parts of the planet could experience a permanent spike in seasonal temperatures within 60 years. (via EurekAlert)
The research team also looked at historical data from global weather stations to see if the projected emergence of unprecedented heat had begun and found that this extreme heat emergence is occurring now and that the climate models represent the historical temperature patterns quite well.
Many tropical regions could see "the permanent emergence of unprecedented summer heat" in the next two decades. Middle latitudes of Europe, China and North America - including the United States - are likely to undergo extreme summer temperature shifts within 60 years, according to the EurekAlert story.
Treating heat stroke.
The report showed that the tropics were heating up the most. I am not sure if the polar regions were included in this study.
Tropical regions may see the most dramatic changes first, but wide swaths of North America, China and Mediterranean Europe are also likely to enter into a new heat regime by 2070, according to the study. (via EurekAlert)
