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 »

Medieval Warm Period in Southern Europe

By | August 27, 2014

Was there really a global Medieval Warm Period? The IPCC used to acknowledge there was; but they have long since changed their view on the subject. Mounting evidence, however, suggests they were wrong to do so; and in this summary, new and important data from Southern Europe that support their original belief are described and discussed.

Effects of Elevated C02 on the Stomatal Conductance of Agricultural Crops

By | July 31, 2014

As the air’s CO2 content continues to rise, nearly all plants will respond by reducing their leaf stomatal apertures, through which water vapor exiting the leaf and carbon dioxide entering the leaf diffuse during transpiration and photosynthesis, respectively. This phenomenon typically leads to an increase in water use efficiency at elevated CO2 concentrations, because with more CO2 in… Read More »

Medieval Warm Period in Central Europe

By | July 24, 2014

Was there really a global Medieval Warm Period? The IPCC used to acknowledge there was; but they have long since changed their view on the subject. Mounting evidence, however, suggests they were wrong to do so; and in this summary, new and important data from Central Europe that support their original belief are described and discussed.

Growth Response of Grassland Species to Elevated C02 When Water Stressed

By | July 15, 2014

As the air’s CO2 content continues to rise, nearly all of earth’s plants should exhibit increases in photosynthesis and biomass production; but climate alarmists periodically claim that water stress will negate these benefits. In reviewing the scientific literature of the ten-year period 1983-1994, however, Idso and Idso (1994) concluded that water stress will not negate the CO2-induced stimulation of plant… Read More »
