INCONVENIENT GLACIERS
Al Gore says the world's glaciers are melting because humanity has emitted too much CO2. However, a new peer-reviewed study shows that in South America‘s Andes Mountains the glaciers' advances and retreats have not been governed by CO2, but by small variations in the sun's intensity.
The study, led by P.J. Polissar of the University of Massachusetts, found that Andean glaciers expanded only four times during the 600 years of the Little Ice Age, which lasted from 1250 AD to 1850.
Each of those glacier advances occurred during a solar minimum, when the sun's lowered activity apparently dropped the mountain-top temperatures by 2-4 degrees C and increased precipitation by about 20 percent.
