It was two years ago that I first wrote about ocean dead zones. These are areas of the ocean that, due to a lack of oxygen, no longer sustain any life.  While dead zones can happen naturally, they usually are caused by the results of human activity.  A primary cause is nitrogen-rich nutrients from agricultural fertilizers that flow into coastal waters from rivers and streams.

Last week there was a report published in the Journal of Science that stated that the number of these ocean dead zones around the world has doubled every decade since the 1960s.  There are …

The two trend lines are the decline in gasoline consumption and the decline in miles driven.  These two are obviously connected and are obviously caused by the price of oil.  For the first time in close to 30 years, we have something to be proud of when it comes to our driving behavior.

Two different reports last week documented this profound turnaround.  A report by the Cambridge Energy Research Associates documented that, should recent behavior continue, gasoline demand will likely decline in 2008 for the first time in 17 years. Over the course of the last 25 years gasoline demand in …

Well, it finally has happened. The price of gasoline has increased enough to cause pain to Americans so that they are changing behavior. The approach of $4 a gallon gasoline has, in the last month produced two positive results. First, after gasoline consumption increased 1.4% in March over the same month last year, it declined 0.6% in April. Second, ridership is up on mass transit systems around the country, in some cases by double digit amounts. The Minneapolis-St.Paul light rail line has increased ridership of 16% year to date over last year, and the Miami rail ridership is up 13% …

Two years ago in this blog, I wrote a futuristic column from April 20, 2009. The title of the column was “Remember When Gas Was Cheap?” At that time I predicted that the price of oil in early 2008 would reach $125 and that in April 2009 it would be $137.
In January of 2007 I was invited on the “First Business” syndicated business program to discuss the price of oil for the remainder of the year. At the time the price was $53 a barrel. I basically told the flabbergasted reporter that I thought the price of oil …
