OSU study: ice ages due to shifts in solar radiation
Researchers at Oregon State University said they have found the reason for the Earth�s ice ages.
They said ice ages are linked to shifts in solar radiation caused by changes in the earth�s rotation and axis and not changes in carbon dioxide levels or ocean temperatures.
Scientists said the findings are important because they will help scientists predict how the earth�s existing ice sheets will react in the future.
Not just the ice -- all aspects of our climate. The Sun is the chief driver and the Sun is a variable star...
