El Nino & La Nina, Environmentalist hype or forboding and prophetic?

Scientists believe that this global warming trend is resulted from the enhanced greenhouse effect. The notion of an "enhanced" greenhouse effect refers primarily to the incremental global warming caused by the exponentially increasing concentrations of anthropogenically introduced greenhouse gases over and above the greenhouse effect caused by naturally occuring greenhouse gases. Although there exist large uncertainties, scientists suggest that the emissions of greenhouse gases and sulfate aerosols could, by the end of the next century, lead to an increase in global mean temperatures of about 1-4 degree centigrate.

El Nino and global warming: What connection?
It's been a hot year, thanks to El Nino. Much to the frustration of environmental activists, however, responsible climate scientists have steadfastly refused to blame the unusually strong El Nino on manmade greenhouse gases. They have also denied any relationship between global warming and hurricanes, putting the lie to politicians who were quick to blame Hurricane Mitch and other weather disasters on the greenhouse effect.

Lots of environmental scares exist without any scientific foundation, but global warming must take the cake when it comes to hype. The late Aaron Wildavsky referred to it as the "mother of all environmental scares." It certainly is the most expensive -- potentially. If the Kyoto Protocol for cutting CO2 emissions and energy use were ever ratified by the U.S. Senate and enforced by the United Nations, there go jobs and prosperity -- all because of the feverish imagination of environmental activists and some computer printouts that don't relate to what's really happening in the atmosphere.
