I think that pretty much everyone is in agreement that some change is occurring in the climate as it has over the eons. The question and where the disagreement lies is in the presumed cause of said change. Certain groups fear that the cause of the climate change is man made due to our use of fossil fuels. They back-up their claim by insisting that "all" the eminent scientists agree and that the science is settled. They maintain that since there is a scientific "consensus" those who disagree present a danger to mankind in their stubborness to accept this "consensus". First of all, the science is not settled! There are many eminent scientists who disagree with the "consensus" and have their statistics to show that the climate is just showing its natural variation. Science, by it's very nature is never settled. All it takes is one contradictory piece of evidence and the "settled" science is out the window. As an example, in the middle ages and beyond all swans were believed to be white. There was never a recorded example of a swan being any other color than white, thus the "consensus" was that science had "settled" on the fact that swans were white. End of discussion! Except in 1697 Dutch mariners traveled to Australia and discovered of all things, black swans! Thus hundreds of years of science and consensus was thrown right out the window! Consensus does not make a theory irrefutable. Early man accepted the "fact" that the movements of the stars and planets were geocentric. Then a young upstart by the name of Copernicus put forth a radical theory that contrary to settled science and the consensus of the scholars of the day is that the earth and the other planets rotated around the sun. Copernicus theory was later confirmed by Johannes Kepler with his three laws of planetary motion.
In summary, I hope I didn't bore you with my treatise. Just be skeptical of the premise of "settled science" and "consensus". Challenge your assumptions about what you "know" to be true and be willing to listen to alternative arguments when they are presented.
