From Meeting 8 Feb 2010

Pinhook Rotary former President, Arch Hill gave a sientific presentation on Global Warming. Today, the effects of co2 on climate change is considered to be 2 times greater than even recent models had predicted. According to Arch, several cycles in the past have been influenced by sun spots. Polution in our current atmosfere, to some extent, reflects the sun's rays as well as holds heat in. He pointed out the use of polar ice caps to measure the effects of increase and decrease of certain gasses over time. The second part, and conclusion to his presentation will be held later this month.
