Another Streak of 90s Brewing On The Horizon
"Ah, summer, what power you have to make us suffer and like it" wrote Russel Baker. Between the urban heat island, "corn sweat" and a dew point pushing 80 degrees, last week's heat index of 112F in the metro was an acquired taste. And there's growing agreement among weather models that a second wave of gasp-worthy heat is shaping up for early August.
A steep lapse rate (temperatures cooling more rapidly with altitude) sparks a few spotty showers and T-showers Tuesday night into Friday. Probably no sustained tropical soakers, and temperatures this week trend closer to average for late July.
Warm sunshine returns for the weekend and by early next week neighbors may be griping about the heat once more, with highs near 90F and dew points in the 70s. Some of the models build another heat dome, a bubble of hot high pressure, directly above the Midwest by the second week of August, potentially capable of a second round of sustained heat & humidity.
MSP has enjoyed 10 days of 90- plus heat in 2016. Average is 13 for the year. At the rate we're going I could see a total of 15-20.

Between 1993 and 2005, when the increase in house size was reaching its zenith, total consumption of electricity for residential air conditioning nearly doubled, from 134 billion kilowatt-hours to 261 billion, according to U.S. Energy Information Administration surveys. The Energy Department says air conditioners use about 5 percent of all the electricity produced in the country each year, costing homeowners more than $11 billion. It’s not too late to reduce our dependence on air conditioning, especially in rural areas, small towns and leafy suburbs. Even in big cities, homeowners can plant shade trees and other vegetation, install whole-house fans, sleep in the basement..."

Life On The Front Line of Climate Change. Here's an excerpt from Horizon Magazine: "...Observations show that the Arctic is warming twice as fast as the rest of world; an alarming trend given its understood role as the world’s barometer of environmental health. Its summer sea ice cover has decreased by about 50 % since the late 1970s, a loss larger than the landmass of India. With sea ice loss outstripping modelled predictions and complete summer loss being a realistic possibility within decades, ICE-ARC is also working to better understand the local and global economic impact of this. The researchers are using their understanding of community vulnerabilities and resilience, along with data collected from sources including autonomous robot platforms, data-sampling buoys and submersibles, to predict what physical and living marine resource changes can be expected — and how fast..."
