Hot enough for ya?

Summertime and the livin’ is easy. Not any more.

A NASA study published last month suggests that summers in my neck o’ the woods here in the eastern USA are going to be pretty brutal in the coming century.

The maps shows results of a computer model projection of average daily maximum temperatures over the eastern United States for July 2085 (left) and July 1993 (right). Areas in violet shading show temperatures of 26°C (79°F); green 30°C (86°F); yellow 34°C (93°F); red 38°C (100°F); dark purple 42°C (108°F). Credit: NASA/GISS.

The researchers used one of the global models from the recently issued climate report by the Intergovernmental Panel on Climate Change (IPCC) to predict future changes in atmospheric circulation patterns resulting from greenhouse gas accumulation. This information was then fed into the weather prediction model to forecast summer-to-summer temperature variability in the eastern United States during the 2080s. They found that extreme summer temperatures developed when CO2 emissions were assumed to continue increasing at about 2% a year, the “business as usual” scenario. According to NASA:

“The research found that eastern U.S. summer daily high temperatures that currently average in the low-to-mid-80s (degrees Fahrenheit) will most likely soar into the low-to-mid-90s during typical summers by the 2080s. In extreme seasons – when precipitation falls infrequently – July and August daily high temperatures could average between 100 and 110 degrees Fahrenheit in cities such as Chicago, Washington, and Atlanta.” 

Ouch.
