With climate change, check scientific literature
To the Editor:
Responding to Global Warming is a Hoax letter to the editor of Oct. 2, 2013.
The author presented information to conclude “The theory that man-made CO2 is the main driver for climate change is incorrect …” The author bases this conclusion on the fact that the climate data for the last 16 years fails to show a global temperature rise and we have experienced fewer tornados and hurricanes than “they” predicted. Without reference citations I cannot validate this conclusion.
I reference both National Aeronautic and Space Administration (nasa.gov) and National Oceanic and Atmospheric Administration (noaa.gov) information on global temperatures. Data from both agencies indicate a general global temperature rise starting in the early 1900s. The data shows a leveling of the rise in the last 15 years. Data published as the “Keeling Curve” (http://scrippsco2.ucsd.edu) show the general rise as well as the leveling in the last 15 years. Those Scripps researchers attribute the leveling to a cyclic ocean cooling period, but expect the temperature rise to continue after the ocean cooling cycle ends. Those same researchers show the global CO2 level rise correlates perfectly with predictions when 57 percent of fossil fuel emissions remain airborne. The climate change data that I found convincing is the “EPICA and Vostok ice core” (Internet search on that name) data which show global temperature and global CO2 levels track each other closely for over 400,000 years.
On a second subject, I have been unable to identify references that support the sea level rise prediction the author offers. Information from the International Panel on Climate Change (IPCC) starting with their 1990 report and the recently published draft of the next report predicts (95 percent confidence level) a rise of 0.26 to 0.54 m (10-21 inches) by 2100.
The author’s last point is that the liberal media and IPCC are alarmists. I suggest the article by Michael Shermer (the Skeptic) in Scientific American of Oct. 2013; “I was a longtime skeptic, mainly because it seemed to me that liberals were exaggerating the case for global warming as a kind of secular Millenarianism — an environmental apocalypse … Then I went to the primary scientific literature on climate and discovered that there is convergent evidence from multiple lines of inquiry that global warming is real and human-caused: temperatures increasing, glaciers melting, Arctic ice vanishing …”
