Tornadoes in New York City? Here's an excerpt from Time Magazine: "The September weather system marks the second time in four months that tornado-like circumstances have touched down in New York. From 1950-1974, the city experienced a dry spell, with no storms on record. But since the mid 70s, seven tornadoes had touched ground, including July 25, 2010′s EF1 system in the Bronx (86-110 mile-per hour winds)."
Topsoil moisture across 63 percent of Minnesota's landscape is said to be Short or Very Short.
Stream flow measurements at reporting stations in the driest areas of the state rank below the 10th percentile when compared with historical data for the date.
The drought situation in northwest Minnesota is the result of an historically dry autumn in 2011, a snow-sparse winter, and a dry 2012 growing season (maps below). The moisture deficits in southern Minnesota developed rapidly due to very hot and very dry conditions over the past eleven weeks (maps below). Over this period, rainfall totals in many Minnesota counties fell short of average by four or more inches. This is the climatological equivalent of missing an entire summer's month worth of precipitation. In some south central Minnesota communities, late-summer rainfall deficits are in excess of six inches."
"...The good news is that creating businesses that will power our growth, and reduce our carbon output while protecting resources, is also the greatest wealth-generating opportunity of our generation. [There is no] choice between growth and reducing our carbon output." - Sir Richard Branson, quoted in a Bloomberg article below.

Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:

Discovery News: At the risk of asking you to distill complex science into a simplistic soundbite: Is climate change affecting the number and intensity of cyclones and hurricanes?
Kerry Emanuel: Most of us think that we are seeing a climate change signal in the North Atlantic, which is by far the best observed and has been observed for the longest period of time; but I hasten to add that only about 12 percent of the world’s tropical cyclones occur in the Atlantic. The other parts of the world are not so well observed.
What we expect from a combination of theory and modeling is that as the climate warms, the actual total number of these storms should decline globally, but the incidence of the severe Category 3, 4 and 5 storms is expected on the other hand to go up. And we do see some indication that the proportion of hurricanes that are intense around the world has been going up, although our data is a bit tenuous and is not for very long, so nobody has a great deal of confidence in it.
