I think global warming is just one cycle in a planet wide history of climate variations. It has been coldern and warmer many times throughout history. The current climate has been warming since the last ice age for 15,000 years ago when NYC was under 500 feet of ice.
Where I am not convinced is that human activity is the primary or major cause of a supposed recent warming trend. Nor am I convinced that scientists can measure with any certainty the future of earth's climate.
Right On My brutha!
