Lawrence Soloman has an interesting piece on a far more probable climate trigger, sunspots. The Sun is the source of most weather and almost all energy on earth.
Sunspots may have a more profound effect on Earth’s climate than previously understood, according to new research published in the scientific journal, Geophysical Research Letters, and presented to the American Meteorological Society.
The research, by Robert Hodges and Jim Elsner of Florida State University, looked at the frequency of hurricanes and sunspots from 1851 to 2008 during the Sun’s 11-year cycles. During periods of low sunspot activity, the researchers discovered, the probability of three or more hurricanes hitting the United States increases dramatically.
“With fewer sunspots, there’s less energy at the top of the atmosphere,” Elsner explained, making for a cooler atmosphere above the hurricane. This differential fuels atmospheric instability, propelling tropical storms into hurricanes.
