In an open letter attacking the Intergovernmental Panel on Climate Change, he wrote: "The ocean is not rising significantly. "The polar ice is increasing, not melting away. Polar Bears are increasing in number. "Heat waves have actually diminished, not increased. There is not an uptick in the number or strength of storms (in fact storms are diminishing). "I have studied this topic seriously for years. It has become a political and environment agenda item, but the science is not valid."
Climate expert William Happer, from Princeton University: "No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science.'
Can a carbon tax save concrete!? 'Climate change may reduce concrete’s durability, with long-term consequences for buildings, roads and bridges constructed with the common material, according to a recent study.
Meet the authors of the 'study': Matthew Eckelman (firstname.lastname@example.org) and Mithun Saha of Northeastern University focused their research on how infrastructure in Boston will be affected by the most extreme climate change scenarios. They predict about 60 percent of Boston’s buildings will have some structural deterioration by 2050. Eckelman and Saha published their study results in the journal Urban Climate.
'Over time both carbon dioxide and chloride ions seep into the concrete and corrode the steel bars, called rebar. This corrosion expands the concrete, destabilizing it. Eventually, the damage becomes visible when the facade of a building cracks or chunks of concrete break off.'
A team of researchers in the U.S. claims that climate models used to predict the rise in CO2 concentrations in the atmosphere are approximately 17 percent too high because they incorrectly approximate how much CO2 plants pull from the atmosphere. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they studied the ability of plants to absorb increased amounts of CO2 and discovered that they are capable of pulling more out of the atmosphere than has been previously thought and the difference is approximately equal to the error difference reported by simulation models.
