“We know who the active [climate-change] denialists are – not the people who buy the lies, mind you, but the people who create the lies. Let’s start keeping track of them now, and when the famines come, let’s make them pay. Let’s let their houses burn. Let’s swap their safe land for submerged islands. Let’s force them to bear the cost of rising food prices….  They broke the climate.”

– Steve Zwick, Forbes, April 19, 2012.

As Chip Knappenberger chronicled earlier this week, there are a number of positive developments in climate science that contradict the doomism and negativity of many climate campaigners. There are benefits, not only costs, to greater carbon dioxide (CO2) concentrations in the atmosphere.

And so it came as a shock, a chill, to read the above quotation from Steve Zwick, the editor of the Ecosystem Marketplace and a contributor (as I am) to Forbes online.…

“Without being a trained climate scientist, I can read the various blogs and try to parse the academic papers, but ultimately I have to rely a lot on the good faith and judgment of the scientists themselves. The Heartland affair has reassured my earlier conviction that the case for climate alarmism is far weaker than the alarmists have been telling us.”

As an economist who has done some research on climate change policies, I am often asked questions along the lines of, “Is the science right or is it really a hoax like Rush Limbaugh says?” My standard reply is to acknowledge first of all that I’m not trained in the field, but to say that from my outsider perspective, it seems that the people warning of imminent catastrophe are vastly overrating the likelihood of their dire forecasts.…

“Advocates of renewable energy feel cornered by the gridlock in Congress and waning interest in climate change. But arguing that renewable energy is the best way to address economic or security concerns isn’t the way to prevail. It just focuses the debate on issues where fossil fuels are almost sure to win.”

– Severin Borenstein, “Making the Wrong Case for Renewable Energy,” Bloomberg, February 13, 2012.

Severin Borenstein, Professor of Business and Public Policy at the University of California at Berkeley, and director of the U.C. Energy Institute, is firmly in the camp of climate alarmism and public policy activism. In a recent op-ed,  Borenstein argues that, absent the climate-change argument, the environmentalists are intellectually adrift trying to argue for their (politically correct) renewable energies–wind and solar (but not ethanol and hydroelectricity, mind you). …

“The forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.”

– James Hansen, “Climate Forcings in the Industrial Era,” Proceedings of the National Academy of Sciences, October 1998, p. 12753.

“In view of the immense power of natural weather and climate fluctuations and the great buffering capacity of the Earth, especially the ocean, it is easy to be skeptical about whether small anthropogenic changes of atmospheric composition can have important practical impacts.”

– James Hansen et al., “How Sensitive Is the World’s Climate?,” National Geographic Research & Exploration, 9(2): 1993, p. 157.

“Climate is always changing. Climate would fluctuate without any change of climate forcings. The chaotic aspect of climate is an innate characteristic of the coupled fundamental equations describing climate system dynamics.”
