Nobel Laureate To Visit Clarkson: Will Make Public Presentation On Antarctic Ozone Hole

POTSDAM, N.Y. -- Few subjects have been more talked-about in this decade than the depletion of the ozone layer, an atmospheric barrier of ozone that lies anywhere from nine to 18 miles above the earth's surface and absorbs ultraviolet radiation and prevents heat loss. The depletion of this layer has led to, among other things, unusual weather patterns, from warmer-than-usual winters to wetter summers. Many scientists believe that such depletion is the result of human doing, rather than nature.

No one knows more about this subject than Nobel Laureate Paul Josef Crutzen, who is the featured speaker for the Clarkson University Center for Advanced Materials Processing's Third Shipley Distinguished Lectureship on September 15-16.

Crutzen's first lecture, "The Antarctic Ozone Hole: A Human Caused Chemical Instability of he Atmosphere," is scheduled for Monday, September 15, at 4:15 p.m. in Science Center Room 312. Areception will be held beforehand at 3:30 p.m.

A second lecture, discussing "The Importance of the Tropics in Atmospheric Chemistry" will be presented on Tuesday, September 16, at 11:15 a.m. in Science Center Room 311. Both lectures are open to the public. According to Clarkson Distinguished University Professor Egon Matijevi , Crutzen's lecture is an important one for those who have a genuine concern for the planet.

We all experience environmental changes, he said, "due to atmospheric chemical changes, so anybody should be concerned about these problems. The effects are global and we will be affected by them because of the influence on the climate in the summer and winter."

Matijevi also said that those who attend will "learn some truths about the ozone hole, because this is still a controversial topic. If it wasn't, there wouldn't be so much written about it. There are some believers and some non-believers, and here, you have a person who really knows the problem intricately, who understands the chemical aspects of it, and the consequences of the problem. So, I think they'll benefit to hear it from the person who knows what is going on from a scientific and an environmental point of view."
