The only thing that came to mind when I read the editorial by Axel Marquardt is that “ignorance is bliss.” The editorial by Clifford Dukes has some relevant information, but his statement about “current means of determining temperature” gives me the impression that he is not aware of the numerous satellites that orbit the earth with sensors that measure surface temperature, surface albedo, aerosols, and numerous other variables that have a bearing on global climate change. Also, his example of an ice cube melting in a glass of water must be amusing to any scientist who understands the forcings (natural and anthropogenic) and the likely results of “global warming.”
Although it would have little bearing on understanding the results of increased global warming, I suggest that he should melt an ice cube in a separate container then pour the resulting water into another container with water to see if the water level would rise.
I suggest that both Mr. Dukes and Mr. Marquardt read the book “Storms of My Grandchildren” by James Hansen (ISBN ISBN 978-1-60819-200-7) In addition to explaining some of the basic concepts of “global warming” and evidence thereof, Dr. Hansen documented the manner by which the Bush Administration suppressed his reporting of scientific research. Of course that was not surprising in consideration that both Bush and Cheney represent the petroleum industry.
Yes, I am one of the 17,000 plus “concerned scientists” who concur with the importance of developing clean energy sources rather to continue the release of carbon dioxide into the atmosphere through burning fossil fuels. It seems to me that even the skeptics of global warming would also want to do this if only to reduce our dependence on foreign oil.
