To the editor:

The scientists signing the Iowa Climate Statement are hugely overconfident in their assertions that we are headed for dangerous global warming and worsening drought. Considering the sun is thought to be entering its weakest cycles in 150 years, we may very well be in for global cooling, not warming; no one knows.

Contrary to popular opinion, the intensity and frequency of extreme weather events are not affected by our emissions of greenhouse gases, even if those emissions cause global warming. The 2011 Nongovernmental International Panel on Climate Change report (NIPCC – see www.nipccreport.com) concluded “…the data reveal there have not been any significant warming-induced increases in extreme weather events.”
