Seeley also points out that a lack of snow (a great insulator) means the frost level is going much deeper this winter:
"The absence of deep snow cover exposed the soil to the Arctic-like cold blast this week. As a result frost depths increased significantly, in some cases going from 4-6 inch depth down to 16 to 20 inches in depth. Actual soil temperatures plummeted as well, dropping into the low to mid 20s F at the 4 inch depth, and into the single digits and low teens F at the shallower 2 inch depth. These low soil temperatures can damage plants, and is one of the reasons so many gardeners use mulch or straw (insulation) to cover the soil in the winter. In agricultural pasture lands and alfalfa fields such low temperatures pose a risk of winter injury."

From a cursory look at our state data base, I selected 8 northern Minnesota climate stations (Baudette, Roseau, International Falls, Big Falls, Itasca State Park, Warroad, Thorhult, and Waskish) with nearly complete histories of daily measurements from 1951 to present. Then I compared the frequency of -40 F or colder over the periods 1951-1980 versus 1981-2010. Seven of the eight climate stations showed a decrease in frequency ranging from 25 percent to over 60 percent fewer occurrences in the 1981-2010 period. The only one that showed an increase in frequency was Waskish, but that station may have moved at one time. Examples of the change in frequency: Itasca State Park recorded 17 nights of -40 F or colder from 1951-1980, and only 11 since 1981 (they have reported no such readings since 1997); Warroad recorded 16 nights of -40 F or colder from 1951-1980, but only 10 since 1981."

- Investments in hurricane resilience should be increased due to projected increases in storm intensity.
- In the long run, the world needs to cut carbon dioxide emissions.
- Investments in renewable energy technology R&D should be dramatically increased.
