Well.....yet more evidence that humans are not the cause of planetary climate change.....
A study of trees living 1000 years ago shows evidence that tempurature change over the last millennium was higher then previously thought and comparable to current global tempurature changes. It also shows that the earth can undergo much larger spontaneous tempurature changes all by itself then previously thought.
Oh well.........
