As scientists, we write to support U.S. Senate candidate Ron Johnson's correct view on natural factors of climate change as reported in the Journal Sentinel (Page 1B
, Aug. 17; Page 1A
, Aug. 21).
This is not a debate about politics or about a belief system. Objective science informs us that the so-called consensus viewpoints offered by the United Nations Intergovernmental Panel on Climate Change about man-made carbon dioxide being the dominant factor of climate change is largely a political conclusion and not likely a scientifically correct one.
If global temperatures are supposedly affected by rapidly rising atmospheric CO2 concentrations but the warming has ceased over at least the last decade, then something more important than atmospheric CO2 must be driving climate change. This is why the National Oceanic and Atmospheric Administration reported Aug. 13 that "greenhouse gas forcing fails to explain the 2010 heat wave over western Russia."
We wish to emphasize that many peer-reviewed publications exist that support the minimal role of atmospheric CO2 as a cause for the weather and climate that we experience. Extremist views only serve to induce panic about climate change, and the unwillingness to address the real science only leads to spurious claims that "the science is settled."
For example, a paper published Aug. 19 in Geophysical Research Letters by a scientist from the California Institute of Technology shows that even the apparently drastic decrease of summer-autumn Arctic sea ice is not unprecedented but merely an effect of Arctic Ocean geography.
We therefore applaud Senate candidate Ron Johnson's stance against CO2-induced climate change.
