"Leslie". Yes, this hurricane is confounding the experts down at NHC. Yesterday it was demoted from a hurricane to a tropical storm. As of late last night it packed 65 mph winds, creeping north at only 3 mph. Models continue to show strengthening, the core of Leslie passing well east of Bermuda, possibly reaching Newfoundland, Canada with 90 mph winds by next Tuesday. Map: Ham Weather.
"...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.

What I'm reading (as if anyone cares):
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.
