Effects of Increased C02 on Herbaceous Plant Pests

By | July 4, 2014

Kerslake et al. (1998)[1] grew five-year-old heather (Calluna vulgaris) plants that they collected from a Scottish moor within open-top chambers maintained at atmospheric CO2 concentrations of 350 and 600 ppm, where at two different times during the study, larvae of the destructive winter moth Operophtera brumata – whose outbreaks periodically cause extensive damage to heather moorland – were… Read More »

Medieval Warm Period in Northern Europe

By | June 25, 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, both old and new important data from Northern Europe that support their original belief are described and discussed.

Loblolly Pines Defy the Progressive Nitrogen Hypothesis

By | June 19, 2014

As part of one of the most outstanding of such studies ever to be conducted, Finzi and Schlesinger (2003)1 measured and analyzed pool sizes and fluxes of inorganic and organic nitrogen in the forest floor and top 30 cm of mineral soil during the first five years of differential atmospheric CO2 treatment of a stand of initially 13-year-old… Read More »

Response of Crustaceans to Ocean Warming

By | June 13, 2014

According to Storch et al. (2009)[1], “temperature is often invoked as the main determinant of distribution ranges and boundaries for marine and terrestrial species,” and they note the larval stages of many marine species “are more vulnerable to thermal and osmotic stresses than adults.” Consequently, they explored the rigidity of this temperature determinant of livable range for the… Read More »

Energy Inefficiencies of Biofuels

By | June 4, 2014

How efficient is it to produce energy from biofuels-is it more, less, or about the same as from traditional fossil fuels? This mini review summarizes what several scientists have learned when investigating this topic.

Response of Marine Plants to Changes in Temperature

By | May 30, 2014

According to the IPCC, CO2-induced global warming will be net harmful to the world’s marine species. One consequence of such harm, is a projected decline in ocean productivity. And in light of what the IPCC frequently refers to as the unprecedented modern rise in global temperature, it might reasonably be expected there should already be signs of a… Read More »

Biofuels: The Carbon Debt They Owe

By | May 21, 2014

In an article entitled “Land Clearing and the Biofuel Carbon Debt,” Fargione et al. (2008)[1] explore what happens when non-agricultural lands are cleared for the growing of biofuel crops. In addition to the destruction of precious habitat needed to support what could be called “wild nature,” this process releases large amounts of CO2 to the atmosphere due to… Read More »

Medieval Warm Period in Japan

By | May 14, 2014

The Medieval Warm Period (MWP) was a global climatic anomaly that encompassed a few centuries on either side of AD 1000, when temperatures in many parts of the world were even warmer than they are currently. The degree of warmth and associated changes in precipitation, however, sometimes varied from region to region, with the result that the MWP… Read More »

Response of Corals to Ocean Acidification

By | May 9, 2014

Over the years, a number of researchers have postulated that many of Earth’s corals are destined to die, with some species even facing extinction, because of the hypothesized connection between the ongoing rise in the air’s CO2 content and reduced rates of coral calcification (Buddemeier, 1994; Buddemeier and Fautin, 1996a,b; Gattuso et al., 1998; Buddemeier, 2001). Kleypas et… Read More »

Interactive Effects of C02 and Water Stress on the Growth of Woody Plant Species

By | May 9, 2014

It is widely acknowledged that as the CO2 content of the air continues to rise, nearly all of earth’s plants will exhibit increases in photosynthesis and biomass production; but climate alarmists periodically proclaim that future water stress will negate these benefits of atmospheric CO2 enrichment. In reviewing much of the pertinent scientific literature of the ten-year period 1983-1994,… Read More »
