More on Cooling Trend

Bloomberg News notes that this is the first year since 1992 when there hasn't been a named storm (i.e., a storm powerful enough to be termed a tropical storm or hurricane) during the peak of hurricane season. From the article:
Since 1995, the basin has been in the midst of what is called the warm phase of the Atlantic Multi-decadal Oscillation. This means it has been warmer than normal and the chances for weaker storms to grow stronger are enhanced, according to the National Oceanic and Atmospheric Administration. 
It has also marked an era where more storms have formed. For example, 21 storms got names from 1992 to 1994 and then in 1995, 19 systems reached that threshold.
A system gets a name when its winds reach 39 miles (63 kilometers) per hour and it becomes a tropical storm.
The warm phase often lasts 20 to 40 years. This is the 20th season since it began. 
Bell said the Atlantic is a little cooler than it has been in past years and if a shift began, it might look something like the current year.

On a related note, "[t]he Canadian city of Calgary, Alberta, home to much of the country's oil and gas industry, suffered through a late-summer snowfall on Wednesday that snarled traffic, downed trees and cut power to dozens of neighborhoods." (Story here).
