"There has been no significant global warming since 1995, no warming since 1998, and global cooling for the past few years," former U.S. Senate Environment Committee spokesman Marc Morano writes at ClimateDepot.com. Citing metrics gathered by Dr. Roy Spencer of the University of Alabama, Huntsville, Morano adds: "The latest global averaged satellite temperature data for June 2009 reveal yet another drop in Earth's temperature ... Despite his dire warnings, the Earth has cooled 0.74 degrees F since former Vice President Al Gore released 'An Inconvenient Truth' in 2006."

Earth's temperatures fall even as the planet spins within what global-warmists consider a thickening cloud of toxic carbon dioxide.

The National Oceanic and Atmospheric Administration's Earth System Research Laboratory at Mauna Loa, Hawaii, consistently and reliably has measured CO2 for the last 50 years. CO2 concentrations have risen steadily for a half-century.

For December 1958, the Laboratory reported an atmospheric CO2 concentration of 314.67 parts per million. Flash forward to December 1998, about when global cooling reappeared. CO2 already had increased to 366.87 ppm. By December 2008, CO2 had advanced to 385.54 ppm, a significant 5.088 percent growth in one decade.

This capsizes the carbon-phobic global-warmist argument. For Earth's temperatures to sink while CO2 rises contradicts global warming as thoroughly as learning that firefighters can battle blazes by spraying them with gasoline.

So, to defeat so-called "global warming," there is no need for the $864 billion Waxman-Markey cap-and-trade bill, the Kyoto Protocols, elaborate new regulations or United Nations guidelines. Instead, let the cold times roll.

It is one thing to have a national debate about a serious problem, with adults differing over which solution might work best. Reasonable people, for instance, can dispute whether growing federal involvement would heal or inflame our health-care system's serious maladies.

But as so-called global warming proves fictional, those who would shackle the economy with taxes and regulations to fight mythology increasingly resemble deinstitutionalized derelicts on an urban street corner, wildly swatting at their own imaginary monsters.
