What causes ice ages?
“Slight shifts in solar radiation caused by predictable changes in Earth’s rotation and axis.”[*1]
In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth’s rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.
The melting was first caused by more solar radiation, not changes in carbon dioxide levels or ocean temperatures, as some scientists have suggested in recent years.
What? Something other than CO2 can be responsible for “climate change?” The hell you say!
