Additional Grounds for Rejecting Biofuels

By | October 31, 2014

In July of 1987, as described by U.S. Department of Agriculture researchers Idso and Kimball (2001)[1], eight 30-cm-tall sour orange tree (Citrus aurantium L.) seedlings were planted directly into the ground at the Agricultural Research Service’s U.S. Water Conservation Laboratory in Phoenix, Arizona, where they were enclosed in pairs within four clear-plastic-wall open-top chambers. Then, in November of… Read More »

The Global Medieval Warm Period

By | October 30, 2014

Between the 10th and 14th centuries AD, earth’s average global temperature may have been warmer than it is today, according to the analyses of Lamb (1977, 1984, 1988) and Grove (1988). The existence of this Medieval Warm Period was initially deduced from historical weather records and proxy climate data from England and Northern Europe. Interestingly, the warmer conditions… Read More »

Growth Rates of Old Versus Young Forest Trees

By | September 25, 2014

The planting and preservation of forests has long been acknowledged to be an effective and environmentally-friendly means for slowing climate-model-predicted CO2-induced global warming. This prescription for moderating potential climate change is based on two well-established and very straightforward facts: (1) the carbon trees use to construct their tissues comes from the air, and (2) its extraction from the… Read More »

Water Use Efficiency of Agricultural Species

By | September 24, 2014

In some cases, the water-use efficiency increases caused by atmospheric CO2 enrichment are spectacularly high. De Luis et al. (1999)[1], for example, demonstrated that alfalfa plants subjected to atmospheric CO2 concentrations of 700 ppm had water-use efficiencies that were 2.6 and 4.1 times greater than those displayed by control plants growing at 400 ppm CO2 under water-stressed and… Read More »

Tropical Trees

By | September 13, 2014

Going back in time to the final few years of the 20th century, Schaffer et al. (1997)[1] grew two mango ecotypes – one evolving from a warm, humid tropical climate, and the other from a cool, dry subtropical region – for 12 months in glasshouses maintained at either 350 or 700 ppm CO2 in order to determine the… Read More »

Global Temperatures and Biospheric Productivity

By | September 11, 2014

Among the many climate-alarmist fears of CO2-induced global warming is the concern that the productivity of the biosphere will decline if global temperatures rise to the extent predicted by computer models. Yet, for many alarmists, the future is the present. Since 1980, for example, the Earth has weathered three of the warmest decades in the instrumental temperature record,… Read More »

Rewriting Sunspot History

By | September 3, 2014

In 2006, when I first made the mistake of writing publicly of my doubts about the Party Line on manmade global warming, I began to receive 100 emails a day from interested members of the public – and of the scientific community. I have been doing my best to answer the best of them ever since. One was… Read More »

The Economics of Biofuels

By | August 27, 2014

Aside from rejecting biofuel expansion and use for environmental reasons (see Biofuels (Land and Water Concerns)[1] and Biofuels (Miscellaneous)[2] in our Subject Index), the production and use of biofuels from an economic perspective does not make much sense either. Proponents of biofuels say their increased production will increase the supply of transportation fuels and therefore lead to lower… Read More »

The Warming-Induced Evolution of Terrestrial Plants

By | August 27, 2014

One of the grandest of catastrophes that climate alarmists contend will result from CO2-induced global warming – which they predict will be unprecedented in terms of both the speed and level of warmth attained – is that many species of plants will not be able to migrate poleward in latitude or upward in altitude fast enough to remain… Read More »
