Global Cooling

By | February 28, 2014

The hypothesis that human emissions of greenhouse gases, especially carbon dioxide (CO2), are causing, or will be causing, dangerous global warming, has been severely criticized on scientific grounds. The critical literature is substantial, not only peer-reviewed scientific papers, but also several substantial scientific books (to mention just a few: Idso and Singer, 2009; Idso, Carter and Singer, 2013a;… Read More »

The Final Final IPCC AR5 WGI Report

By | February 22, 2014

The Fifth Report of the Intergovernmental Panel on Climate Change WGI Report Climate Change 2013: The Physical Science Basis has at last appeared on the IPCC website at http://www.ipcc.ch/report/ar5/wg1/. The last Fifth Report, which was received at Stockholm in September 2013, approved the Summary for Policymakers but merely accepted the rest of the Report, pending further amendment. They… Read More »

Rising Atmospheric C02 and Soil Erosion

By | February 21, 2014

Almost from the beginning of scientific interest in the subject, study after study had concluded that soil erosion by both wind and water was a major environmental problem. In fact, in an article published in Science a decade and a half ago, Trimble and Crosson (2000)[1] noted that “some sources have suggested that recent erosion is as great… Read More »

Medieval Warm Period in the Contiguous United States

By | February 13, 2014

Climate alarmists claim that rising atmospheric CO2 concentrations due to the burning of fossil fuels, such as coal, gas and oil, have raised global air temperatures to their highest level in the past one to two millennia. And, therefore, investigating the possibility of a period of equal global warmth within the past one to two thousand years has… Read More »

Evolution in Natural Vegetation: The Role of C02

By | February 6, 2014

Some two decades ago, Root and Schneider (1993) wrote that CO2-induced changes in global climate were expected – by them and other climate alarmists – to occur “too fast for evolutionary processes such as natural selection to keep pace,” while adding that this phenomenon “could substantially enhance the probability of extinction of numerous species.” This famous but unsubstantiated… Read More »

Lindzen Libeled

By | February 6, 2014

Dana Nuccitelli of Unskeptical Science has written a characteristically spiteful piece in the Guardian about Professor Lindzen. The piece constitutes a grave libel. Britain, still to some extent a free country, is one up on the U.S. in allowing anyone – even a public figure – to sue for libel, especially where, as here, he is libeled in… Read More »

Health-Promoting Effects of Elevated C02 on Medical Plants

By | February 5, 2014

How will the ongoing rise in the air’s CO2 content alter the amounts and concentrations of various health-promoting substances produced by medicinal or “health food” plants? This question was broached early on by Stuhlfauth et al. (1987), who found that a near-tripling of the air’s CO2 content increased the dry weight production of the woolly foxglove plant (which… Read More »
