The Year Of The Man-Made Global Warming Skeptic
In 2008, scientists from all over the world are jumping off the man-made global warming bandwagon. This is due to the fact that environmental study after study concludes that the behavior of man is not the cause of significant global warming.
In a recently released Geological Society of America abstract, Dr. Don Easterbrook, Professor of Geology at Western Washington University, presented data showing that the global warming cycle from 1977 to 1998 is now over and that we have entered into a new global cooling period that should last for the next three decades.
He also suggests that since the IPCC climate models are now so far off from what is actually happening that their projections for both this decade and century must be considered highly unreliable.
Meanwhile, David Douglass and John Christy, in a paper just accepted for publication and now available on the internet, have come to the conclusion that natural changes in global water temperature are responsible for an increase in global temperature. Here is their scientific conclusion:
"El Nino and La Nina effects in the tropics have a more significant affect on global temperature anomalies than carbon dioxide, in particular it was an El Nino event that drove the 1998 global temperature maximum".
At NASA, Dr. Roy Spencer, believes natural cycles account for most of last century’s warming, with carbon dioxide increases contributing only a modest amount.
His new research, which was submitted to Geophysical Research Letters for publication, shows that climate models overstate the positive feedback from an increase in carbon dioxide, and therefore grossly overstate the projected warming during the next century
In addition, two new studies (article in Science Magazine) point to wind-induced circulation changes in the ocean as the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets, not ‘global warming.’
In June, Dr. David Evans, an architect of Australia’s Kyoto compliance, and for years a noted climate change alarmist, became the latest man-made global warming doubter. Evans outlines the four main reasons why 2008 has become the year of the global warming skeptic and why he recently jumped off of the global warming bandwagon.
1.The missing “greenhouse signature”, which would be a hot zone about 10 km up in the atmosphere. It’s been sought for years - hundreds of measurements using radiosondes (a sort of temperature measuring weather balloon). It would constitute the smoking gun . Hundreds of tests have returned the same answer - it’s not there. It is statistically impossible that the hundreds of tests missed the spot. The existing models on greenhouse warming do not work without this hot zone.
2. “There is no evidence to support the idea that carbon emissions cause significant global warming” says Evans. “None". There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though by how much is hotly disputed) but there are no observations” constituting evidence that carbon emissions are a significant driver in warming trends.
3. Satellites measuring the world’s temperature uniformly show that the warming trend stopped in 2001 and that in the past year the temperature actually returned to 1980 levels. Satellite measurements are the only truly reliable method for capturing the data as land-based measurements are vulnerable to encroachments of expanding cities and “urban heat island effect.”
4.“The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.”
As global temperatures continue to cool and research against man-made global warming continues to pile up, as scientists abandon the man-made global warming bandwagon one thing is becoming increasingly clear. The cause of global climate change should be based on facts and evidence and not just our fear.
