Sudden, Dramatic Climate Changes Over Time



The above video shows temperature changes over time based on Greenlandic ice cores. As one goes back in time further and further towards 40,000 years ago and beyond, it becomes clear that there were sudden, dramatic climate changes in the shape of hockey sticks. While one can argue over the benefits of global and regional climate changes it is clear that we live on a planet full of changes.

Those who argue that 'we live on a planet' do so only so they won't be shunned and cast out of their comfortable positions inside the ivory tower.

Exberance,
I hope you weren't implying that I have a position in an ivory tower. If so, please tell me where it is because I didn't know I did!
