Ozone Holes and Record Heat: Good News….Maybe

Posted on 22 November 2012 by Jerry

The good news is destruction of the ozone and hence the size of the ozone hole over Antarctica has diminished to a point that is the second smallest of the last 20 years. Last year’s new ozone hole over the Arctic, which caused great consternation, has not reappeared and its stratospheric ozone appears to have returned to a normal range. This might indicate that the objective of the 1987 Montreal Protocol, signed twenty-five years ago this September, is beginning to be realized.  Or it might indicate that ozone holes, which depend on ultra cold temperatures in the stratosphere, do not form in the face of record heat and/or climate change. It is too soon to tell but any lessening of ozone destruction is a good outcome.

The National Climate Data Center Chief, Deke Arndt, reports that 2012, at the present rate, will be the warmest year in the past 100 years in the United States (see the video presentation on the third link identified below).  With 16 months of average temperatures above normal, this year will break records for the warmest March, the warmest spring, the warmest July and the third warmest summer.  The old records will be exceeded by a wide margin.

This year’s Antarctic ozone hole covered an average area of only 6.9 million square miles (17.9 million square kilometers).  The largest size of this year’s ozone hole was reached on September 22, when the hole covered 8.2 million square miles or an area the size of the United States, Canada and Mexico combined.  This is however, significantly smaller than the record ozone hole which encompassed 11.5 million square miles (29.9 million square kilometers) in 2000.

While climate scientists do not have enough information to correlate the diminishing destruction of the ozone with the rising temperatures of the United States and the world, the possibility of a relationship is a reality.  In any case, the shrinking of the ozone hole(s) means the ultraviolet radiation humans receive is lessened which reduces the incidence of skin cancers and other maladies.

Record Warmest Year in U.S.

Posted on 05 July 2012 by Jerry

The April 2012 report from the National Oceanic and Atmospheric Administration’s National Climatic Data Center declares that when April is added to the first three months of 2012 or when it is added to the previous 11 months stretching into 2011, they calculate it “to be the warmest year-to-date and 12 months periods since record keeping began in 1895,” or one hundred and seventeen years.  If you compare the one year average U. S. temperature with the average temperature between the years 1901 to 2000, this year has a higher average temperature, up 2.8°F.  Comparing the first four months of this year with the long-term annual average, the first four months of 2012 were 5.4°F higher.

Given the national temperatures, extended drought, and heat wave engulfing the U.S. in May – June and continuing this month, 2012 may yet again set a record. This graphic evidence cannot be lost on climate deniers. Paraphrasing a quote from Shakespeare’s Hamlet, Act III, scene II, “Me thinks they protesteth too much.”  The lengths to which they are going to suppress reminders of the problem is significant.  To some of us it indicates they privately know there is a problem.

An article in the June 28, 2012 edition of Nature magazine, entitled “Sea Versus Senators” focuses on just one small aspect of how local and state governments and their business communities are trying to hide the validity of climate science. The North Carolina House of Representatives rejected a law passed in the state senate forbidding scientists in state agencies from using exponential extrapolation to predict sea-level rise.  They compromised however, by limiting the scientists to only linear extrapolation for the next three to four years while the state conducts a new sea-level study.  Similarly, the Texas Commission on Environmental Quality removed all references to rising sea levels from a study of Galveston Bay in the Gulf.  In addition, the Virginia General Assembly commissioned a study of rising sea levels only after references to sea-level rise and climate change had been removed from the bill.

What all of these locations have in common is active real estate and tourist businesses. Legislators and businessmen are afraid of further depression in their coastal real estate markets and future reduced tourism because of the fear of rising waters.  This is called “cutting off one’s nose to spite one’s face.”  To the extent that avoiding reminders of climate change, which they know is real, lulls the larger population into ignoring the worsening problem, these businessmen and legislators put off initiation of real solutions which makes their ultimate catastrophe even worse.
