THE melting of sea ice at the North Pole may be the result of a centuries-old natural cycle and not an indicator of man-made global warming, Scottish scientists have found.Cyclical. That's what I said.
After researching the log-books of Arctic explorers spanning the past 300 years, scientists believe that the outer edge of sea ice may expand and contract over regular periods of 60 to 80 years. This change corresponds roughly with known cyclical changes in atmospheric temperature.
The finding opens the possibility that the recent worrying changes in Arctic sea ice are simply the result of standard cyclical movements, and not a harbinger of major climate change.
