If It's Summertime, It Must Be Global Warming Time

Yet another voice of reason:

The public-service announcements are all similarly big on melting polar ice caps and consequent rises in sea level. The Arctic cap loses ice in the summer, but no one bothers to mention that we only began collecting data on it in 1979, at the end of the second-coldest period in the Arctic in a century. The ice had to be abnormally expanded then.

It’s also floating ice, and melting it and doesn’t change sea level at all. And, for all the headlines about loss of ice in Greenland, which does contribute to rising sea levels, the mean temperature there was much higher from 1910 through 1940. Between then and the late 1990s, temperatures in southern Greenland — the region where ice is melting — declined sharply. One has to presume that Environmental Defense knows this.

Around the world, in Antarctica, for the last few decades, average temperatures across the continent have been going down. Snowfall has increased, resulting in more continental ice. In fact, every modern computer simulation of 21st century climate has Antarctica continuing to accrete ice.

Ogilvy and Mather marketed their public-service announcements through the Ad Council, whose website says that “reversing the global warming trend is possible.”

This suggests that humans have the power to turn planetary warming into cooling — a scientific absurdity. We have neither the technology, the means, the money, nor the political will to do this.

Consider the Kyoto Protocol, a “baby step” in the fight against global warming. It “requires” the U.S. to reduce its emissions of carbon dioxide to seven percent below 1990 levels by 2008-2012. Requirements vary by a percent or so for most other signatories such as Canada and the EU nations. Yet if every nation of the world met its Kyoto targets, the amount of warming that would be prevented is .07 degrees Celsius per half-century — an amount too small to even measure, as average surface temperatures fluctuate by about twice that much from year to year.

Neither the U.S. nor the EU nor virtually anyone else will be able to fulfill the Kyoto targets. EU emissions rose last year, while U.S. emissions remained unchanged. “Reversing” warming would require reducing carbon-dioxide emissions by 60-80 percent, which is simply impossible. The world economy would implode.

Ogilvy and Mather’s corporate website feature a quote from founder David Ogilvy: “We pursue knowledge the way a pig pursues truffles.” But what about knowledge on hurricanes, ice caps, and the real possibilities with respect to global warming?

In this case, these pigs are pursuing theoretical truffles which exist only in a computer simulation run by somebody chasing grant money.
