Global warming and tree rings in Finland

Category: Al Gore,global warming,Group-thinkharmonicminer @ 9:06 am

An interesting article on Finnish tree ring studies which have been reconstructed to provide a 7000 year baseline of temperature changes, given the sensitivity of tree growth to temperature variation. The whole article is worth scanning, but the money quote is:

…a case for recent warming can be made based on the tree-ring record, but the recent warming is paled by many past events including many red-hot summers in Finland 7,000 years ago. If nothing else comes from their figure, be keenly aware that climate always changes – flat line periods simply do not exist!

In other words, sure, the climate is changing… again. It always has. But those changes have had nothing to do with human inputs, and current changes (which are overblown according to many experts) probably don’t have much to do with humans, either.
