Biospheric Productivity of China Deserts

By | December 11, 2013

Climate alarmists are continually warning about the 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 thus review how deserts have fared throughout China in response to rising air temperatures and atmospheric CO2 concentrations, which climate alarmists characterize as unprecedented over thousands of years (in… Read More »

Historical Temperature Trends in Asia

By | December 4, 2013

At a time when we’re told that the world is hotter than it’s been over the past thousand or more years, this information is not exactly what one would expect to hear, unless, of course, the claim is wrong. And, in fact, that is what it appears to be; for a number of real-world (as opposed to climate-model)… Read More »

Growth Response of Aspen Trees to Elevated Carbon Dioxide and Ozone

By | December 3, 2013

Karnosky et al. (1999)-1 described how they had grown O3-sensitive and O3-tolerant aspen clones in 30-m diameter plots at the Aspen FACE site near Rhinelander, Wisconsin, USA, where the young trees were maintained at atmospheric CO2 concentrations of either 360 or 560 ppm either with or without exposure to elevated O3 (1.5 times the ambient ozone concentration). And… Read More »

Grand Minimum of the Total Solar Irradiance Leads to the Little Ice Age

By | November 25, 2013

Significant climate variations during the past 7.5 millennia indicate that bicentennial quasi-periodic TSI variations define a corresponding cyclic mechanism of climatic changes from global warmings to Little Ice Ages and set the timescales of practically all physical processes taking place in the Sun-Earth system. Quasi-bicentennial cyclic variations of the TSI entering the Earth’s upper atmosphere are the main… Read More »

Modern Growth Trends of Earth’s Forests

By | November 20, 2013

How well have earth’s forests been faring during the modern era? This question was asked a few years ago by five researchers (Lapenis et al., 2005[1]), who sought the answer by analyzing trends in forest biomass in all 28 ecoregions covering the Russian territory, based on data collected from 1953 to 2002 within 3196 sample plots comprised of… Read More »

Natural and Anthropogenic Perturbations in Cloud Albedo

By | November 15, 2013

Understanding how clouds respond to anthropogenic-induced perturbations of our planet’s atmosphere is of paramount importance in determining the impact of the ongoing rise in the air’s CO2 content on global climate; for as Charlson et al. (2001) have noted, “man-made aerosols have a strong influence on cloud albedo, with a global mean forcing estimated to be of the… Read More »

Plant Productivity: Growth Response to C02 When Coupled with Ozone

By | November 7, 2013

Ozone (O3) is the primary air pollutant responsible for visible foliar injury and reduced growth in trees the world over. Most studies of the subject suggest it gains entrance to leaves through their stomata, whereupon it interferes with the process of photosynthesis and thereby reduces plant productivity. The global significance of the phenomenon was described in some detail… Read More »

Historical Temperature Trends in Antarctica

By | October 30, 2013

From the birth and death of ice ages to the decadal meanderings of modern-day weather patterns, studies of Antarctica bear witness to the fact that the atmosphere’s CO2 concentration is not a major player in bringing about significant changes in earth’s climate; and in what follows, the case for this proposition is presented in the form of brief… Read More »

Medieval Warm Period and the World’s Oceans

By | October 29, 2013

Keigwin (1996) introduced his classic paleoclimatic study of the northern Sargasso Sea by stating that “it is important to document natural climate variability in order to understand the effects of anthropogenic forcing.” And, therefore, working with two subcores of a sediment box core retrieved from 33°41.6’N, 57°36.7’W of the undulating plateau of the northeast Bermuda Rise, he measured… Read More »
