Global warming ideas disputed by PSU prof

By VICTORIA GUAY | The Citizen

While a large number of people, including some scientists, believe that we are in an unprecedented period of global warming caused primarily by humans, Dr. James Koermer, a meteorology professor at Plymouth State University, would beg to differ.

During a presentation at the university on Wednesday, Koermer explained why there are a growing number scientists, such as himself, who don’t subscribe to the popular theory on global warming.

Koermer said the Earth’s climate has always changed and has experienced alternate warming and cooling trends long before the dawn of man.

Koermer said most research suggests that at the beginning of the last millennium, there was a global warming period that ended around 1600, when a significant cooling trend — which he called a mini ice age — lasted for approximately 100 years.

The most recent global warming trend picked up during the 1700s, which coincides with the start of the Industrial Age, Koermer said.

Going back millions of years, some research suggests the Earth has had much more extreme climate changes than are occurring today.

“Over millions of years there have been periods when we have been hotter than we are today,” Koermer said.

He added that while humans do have an impact on the climate, it is minimal compared to natural phenomena. He also said that humans are not the biggest producers of carbon dioxide and that the gas is not the most abundant green house gas in the atmosphere. That title goes to water vapor, which is produced by the world’s oceans.

Koermer said that water vapor is responsible for 95 percent of the green house gas effect in a given year while another 4.72 percent is caused by a mix of other greenhouse gases, including methane, nitrous oxide and carbon dioxide, which are naturally produced.

Humans are only responsible for .28 percent of all greenhouse gases produced during a year, he said.

    It is sad when a scientist is so self-deluded as to imagine that his uninformed opinion is somehow relevant. He should realize that if his thoughts had any substance whatsoever he should publish them in the scientific literature.

    Koermer would be quite justifiably appalled if a medical researcher or a scientists from some other discipline made statements as misinformed and transparently false about meteorology as these are about climatology. He would be right in suggesting that such people should trouble themselves to learn the science before commenting, and I am suggesting he should do so.
