Global Warming vs. Reality

Global warming is back in the news. Yet, in spite of the alarmists' cries of, "Resistance is futile!" it looks like the skeptics are winning. At least, that's what Nature is telling us.

Peter C. Glover's February 23, 2009, article in American Thinker addresses the question of global warming.

There's nothing more the climate alarmist media loves than a 'melting Arctic' ice cap story. So why not stories from the far larger expanse of ice that is the 'melting' Antarctic? Well it might have something to do with the fact that the Antarctic ice grew to record levels in 2007 - and continues to grow.

Climate scientist Dr Ben Herman, past director of the Institute of Atmospheric Physics and former head of Atmospheric Sciences at the University of Arizona, notes that for the media, "What happens in the Arctic may be an indicator of what will happen in the rest of the world. How about what happens in the Antarctic then? Since its ice area has been increasing, is this also an indicator of what might be happening in the rest of the world?" The FACT is that the majority of Antarctica has cooled over the past 50 years and ice coverage has grown to record levels. Take the well-publicized collapse of a 160 square mile block of the Wilkins Ice Shelf in Antarctica in March 2008. For the alarmist media this was conclusive proof of the dramatic global warming effects. The Los Angeles Times ran, 'Antarctica Collapse' referring to the "rapid melt of the Wilkins Shelf". The Sydney Morning Herald ran 'Ice Shelf Hangs By a Thread' and the Salon online news site had the absurd headline 'Bye-bye Antarctica?' But Joseph D'Aleo, first Director of Meteorology at The Weather Channel and Chief Meteorologist at Weather Services International, was more prosaic. On his IceCap website, D'Aleo wrote that the collapse was the equivalent, given the enormity of Antarctica, of "an icicle falling from a snow and ice covered roof." He added, "The latest satellite images and reports suggest the ice has already refrozen around the broken pieces. In fact the ice is returning so fast, it is running an amazing 60 percent ahead of last year when it set a new record." Noting the ludicrous media hype, D`Aleo laments, "Yet the world is left with the false impression Antarctica's ice sheet is also starting to disappear."

In December 2006, Dr Duncan Wingham, Professor of Climate Physics at University College London and Director for Polar Observation and Modelling, presented evidence that showed "Antarctic thinning was no more common than thickening". Wingham and his colleagues found that 72 percent of the Antarctica ice sheet was growing at the rate of 5 millimetres per year. Most significantly, Dr Wingham commits media heresy when he states: "That makes Antarctica a sink, not a source, of ocean water. According to their best estimates, Antarctica will 'lower global sea levels by 0.08 mm' per year." Sacrilege.

Yes, you say, but what about the melting Arctic? That's real, isn't it?

During October and November 2008 the extent of Arctic ice was 28.7 percent greater than during the same period in 2007. According to data published by the International Arctic Research Center (IARC/JAXA) October 2008 saw "the fastest ever growth" of Arctic Sea ice since records began.

A NASA study published in the peer-reviewed Geophysical Research Letters in October 2007 had already noted that thinning Arctic ice was more likely the result of "unusual winds" that had blown "older thicker" ice into warmer southern waters. In other words, the Arctic warming experienced more recently could well be the result of the unusual strength of winds, not man-made warming.

According to the National Snow and Ice Data Center's own figures, world sea ice in April 2008 reached "unprecedented" levels for the month of April. The World Meteorlogical Organization (WMO) went to declare 2008 the coolest since 2000.

Moreover, the WMO reports that the fall in the global mean temperature since 1998 is not just affecting the polar ice caps either, it is also affecting glaciers elsewhere.

Glaciologist Bruce Molnia of the US Geological Survey said, "In mid-June, I was surprised to see snow still at sea level in Prince William Sound." He adds "On the Juneau Icefield, there was still 20 feet of new snow on the surface in late July. At Bering Glacier, a landslide I am studying did not become snow free until early August." In short, 2008 was the first time since record began that Alaskan glaciers did not shrink during the summer months.

In late November 2008, reports from Norway showed that Alaska's glacier experience was being replicated there too. Hallgeir Elvehoy of the Norwegian Water Resources and Energy Directorate (NVE) reported that the magnitude of glacial growth appears to have been underway for two years. Glacier growth has also been reported from Canada and New Zealand.

Still, the global warming alarmists insist that their message is true. We must Do Something to save the planet from becoming awash in glacial meltage, they say. Sadly, President Obama is listening to the alarmists and not to the truth.
