Wobble


While politicians, bureaucrats and social engineers around the world debate carbon targets and emissions trading schemes, science continues to pop out research that casts doubt on climate modelling.
One of the cornerstones of the humans-did-it climate debate has been a rise in CO2 levels at the end of the ice age. Climate change proponents point to this rise as "proof" that evil CO2 is responsible for global warming, while skeptics point to the disparity in timing, showing that the rise in CO2 comes AFTER a warming event, therefore can't be its trigger.
An article published today in Science Daily headlined "Long Debate Ended Over Cause, Demise Of Ice Ages?" would seem to support the nay sayers.
Researchers at Oregon State University and other institutions blame known wobbles in Earth's rotation. This imperfection, they say, 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 ending the last ice age and delivering our currently enjoyed mild climate.
They further suggest that their research proves that melting was first caused by more solar radiation, not changes in carbon dioxide levels as suggested by the pro human-caused climate change proponents.
Ah well. I suppose we shouldn't expect facts to get in the way of a good story, so carbon-induced climate doom will remain on front pages everywhere.
