Climate change: Global cooling?

"Further ammunition for global warming skeptics came from south of the border, where a Mexican scientist warns that Earth will enter a “little ice age” for up to 80 years because of a decrease in solar activity.

Victor Manuel Velasco Herrera, a researcher at the Institute of Geophysics at Mexico’s National Autonomous University, predicts that the ice period will begin in about 10 years.

Predictions of a gradual increase in temperatures called global warming are erroneous, Velasco Herrera told a conference at the Centre for Applied Sciences and Technological Development regarding predictions of the Intergovernmental Panel on Climate Change (IPCC).

The IPCC models and forecasts are wrong because they are based only on “mathematical models and presented results at scenarios that do not include, for example, solar activity," he said.

The phenomenon of climate change should include other kinds of factors, both internal, such as volcanoes and human activity, and external, such as solar activity, he said.

"In this century, glaciers are growing," as seen on the Perito Moreno mountain in the Andes; on Mount Logan, the highest mountain in Canada; and on Franz-Josef Glacier, New Zealand, Velasco Herrera said.

Satellite data indicate that a period of global cooling may have begun in 2005, he said."
