Biospheric Productivity in Africa

By | November 29, 2012

Nearly three decades ago, Idso (1986) published a small item in Nature that advanced the idea that the aerial fertilization effect of the CO2 that is liberated by the burning of coal, gas and oil was destined to dramatically enhance the productivity of Earth’s vegetation. In fact, in a book he had published four years earlier (Idso, 1982),… Read More »

Biospheric Productivity in Asia, Excluding China

By | November 29, 2012

Climate alarmists are continually warning the world about potentially-catastrophic negative consequences of CO2-induced global warming, which they contend will wreak havoc with Earth’s natural and agro-ecosystems. In this summary we review how vegetative productivity has fared throughout various countries in Asia outside of China over the past few decades, when air temperatures and atmospheric CO2 concentrations have risen… Read More »

The Unbalance Sheet

By | November 22, 2012

The concept of the balance sheet is important to the provision of information over a wide range of human activities, particularly in science and finance. The weasel words Off Balance Sheet have historically been used by shady businesses to hide items that represent hidden liabilities and risks[1]. They were a significant factor in the build up to the… Read More »

Droughts in Africa

By | November 14, 2012

One of the many dangers of global warming, according to the world’s climate alarmists, is the predicted propensity for rising temperatures to produce more frequent, more severe, and longer-lasting droughts almost everywhere on Earth. But just how realistic are the climate models upon which these claims are based? And what does real-world climatic history have to say about… Read More »

Nutrient Acquisition in a C02 Enriched World

By | October 31, 2012

On a per-unit-biomass basis, Smart et al. (1998) noted there were no differences in the total amounts of nitrogen within CO2-enriched and ambiently-grown wheat seedlings after three weeks of exposure to atmospheric CO2 concentrations of 360 and 1,000 ppm. Nevertheless, the CO2-enriched seedlings exhibited greater rates of soil nitrate extraction than did the ambient-grown plants.

Climate Predictability

By | October 26, 2012

This well at Kom Umbu on the banks of the Nile River was built in Roman times. It was connected to the river. The relationship could be calculated between the number of steps inundated each year and the extent of the area that was inundated by beneficial flood water, and was therefore taxable,. This was the world’s first… Read More »

Interaction of C02 and Light on Plant Growth

By | October 18, 2012

Granados and Korner (2002)1 grew three tropical understory vines (Gonolobus cteniophorus, Ceratophytum tetragonolobum and Thinouia tomocarpa) for seven months in controlled environment chambers maintained at atmospheric CO2 concentrations of 280, 420, 560 and 700 ppm in combination with low and high light intensities to study the interactive effects of the two parameters on the vines’ growth. On average,… Read More »

Heavy Metal Soil Toxicity in a C02-Enriched World

By | October 18, 2012

Noting that copper (Cu) is “an essential micronutrient [that] plays a vital role in maintaining normal metabolism in higher plants,” but that it “is toxic to plant cells at higher concentrations and causes the inhibition of plant growth or even death,” Jia et al. (2007)1 grew a Japonica rice cultivar in control and Cu-contaminated soil for one full… Read More »

Sea Ice: An Open Letter to Jeremy Paxman of the BBC

By | October 15, 2012

Your Newsnight segment on Arctic sea ice (BBC2 TV, 8 September 2012) featured a “scientist” who said ice loss since a high point in 1979 would cut the Earth’s albedo and, by this feedback, cause warming equivalent to 20 years’ global CO2 emissions. On the IPCC’s current central climate-sensitivity estimates, 20 years’ CO2 emissions would only warm the… Read More »
