The Evidence......
just keeps mounting..... this is one situation where it won't be pleasant to say "I told you so"...
John England, a geologist who was with the team that spotted the earlier grizzly.
"If we want evidence for climate change, we don't have to go to an isolated occurrence of a grizzly bear somewhere," said England, who holds a northern research chair on environmental change in the Arctic.
"The satellite imagery showing sea ice reduction over the last 30 years is proof positive of very dramatic changes in the northern hemisphere."
No one disputes that warming and cooling cycles are natural and have happend before.....
Its the SPEED at which the climate is changing that is at issue and supports with little doubt that CO2 generated by fossil fuels is the chief culprit. While changes happened in the past never has the change been so rapid. Ice cores and tree ring fossils demonstrate the past patterns over thousands of years regarding rates of warming and cooling and the evidence is undeniable.
