WASHINGTON – This may come as bad news for Al Gore.

The modest global warming trend has stopped – maybe even reversed itself.

And it's not just the record low temperatures experienced in much of the world this winter.

For at least the last five years, global temperatures have been falling, according to tracking performed by Roy Spencer, the climatologist formerly of NASA.

"Global warming" was going to bring more and more horrific hurricanes, climate change scientists and the politicians who subscribed to their theories said. But since 2005, only one major hurricane has struck North America.

A new study by Florida State University researcher Ryan Maue shows worldwide cyclone activity – typhoons, as well as hurricanes – has reached at least a 30-year low.

Two more studies – one by the Leibniz Institute of Marine Science and the Max Planck Institute of Meteorology in Germany and another by the University of Wisconsin – predict a slowing, or even a reversal of warming, for at least the next 10 to 20 years.

The Arctic sea ice has grown more on a percentage basis this winter than it has since 1979.

The number of polar bears has risen 25 percent in the past decade. There are 15,000 of them in the Arctic now, where 10 years ago there were 12,000.

"The most recent global warming that began in 1977 is over, and the Earth has entered a new phase of global cooling," says Don Easterbrook, professor of geology at Western Washington University in Bellingham, confidently. He maintains a switch in Pacific Ocean currents "assures about three decades of global cooling. New solar data showing unusual absence of sun spots and changes in the sun’s magnetic field suggest ... the present episode of global cooling may be more severe than the cooling of 1945 to 1977."

Climatologist Joe D’Aleo of the International Climate and Environmental Change Assessment Project, says new data "show that in five of the last seven decades since World War II, including this one, global temperatures have cooled while carbon dioxide has continued to rise."

"The data suggest cooling not warming in Earth's future," he says.
