"...Since roughly 1980, the United States has seen a total of 107 weather-related disasters of over $1 billion each in damage, with total losses exceeding $750 billion."
"....The economic impact of severe weather events is only projected to grow," Senator Dick Durbin said at a hearing of the Senate Subcommittee on Financial Services and Government, which he chairs. "We are not prepared. Our weather events are getting worse, catastrophic in fact." - Reuters article on extreme weather. Details below.
"Using the Twin Cities climate records since 1980, the normal number of days each year with dew points of 70° F or higher is 23. The all-time record year for dew points of 70° F or higher is 2002 with 48 days.

"The excessive heat that enveloped much of North America during the last half of July has certainly caused a variety of short-term impacts for businesses and consumers. Companies that sell air conditioners, fans, cold beverages, swimwear and other similar products have benefited from a surge in demand. On the other hand, consumers looking to beat the heat scaled back on certain products, services and activities.
As the extreme heat subsides and more normal summer temperatures return, there are some longer-term, lasting effects that the recent weather will have on the economy.
August Electricity Bills = Higher Costs & Reduced Spending Power
Planalytics’ Power Weather Index (a measure that isolates the impact of temperatures on electric demand) is showing the following for the U.S. as a whole:
- +2% vs. July 2010 (Note: last year was the second warmest July in 50 years!)
- +6% vs. the 10-year average
- Many metropolitan areas in the Midwest & Northeast saw even larger increases during the last half of the month (St. Louis +16%, Chicago +14%, Cleveland +11%, Philadelphia +11% vs. the 10-year average)
Economic impacts for households and businesses include:
- Significantly higher August utility bills will claim a greater share of household disposable income leaving fewer dollars to spend on dining out, back-to-school shopping, etc.
- For many, disposable income has already taken a hit with unplanned purchases of air conditioners and fans or repair/servicing costs for home and car air conditioners that malfunctioned under the strain of heavy use.
- Higher electricity bills will increase manufacturing costs for many businesses, putting upward pricing pressure on finished goods sold at retail.
Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
— 14% of the general public doesn’t worry about climate change at all, but among CWMs the percentage jumps to 39%.
— 32% of adults deny there is a scientific consensus on climate change, but 59% of CWMs deny what the overwhelming majority of the world’s scientists have said.
