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 the case of temperature) to millions of years (in the case of CO2 concentration).

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) studies provide evidence that Asian temperatures during the first half of the past century and earlier were sometimes much warmer than they have been over the past couple of decades. And some of them suggest that temperature trends of the past few decades have actually been negative, rather than positive.

Growth Response of Aspen Trees to Elevated Carbon Dioxide and Ozone Print E-mail

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 there, after one year of growth at ambient CO2, they determined that the elevated O3 had caused visible injury to leaves of both types of aspen, with the average percent damage in O3-sensitive clones being more than three times as great as that observed in O3-tolerant clones (55% vs. 17%, respectively). In combination with elevated CO2, however, the O3-induced damage to the leaves of these same clones was only 38% and 3%, respectively. And so they learned that elevated CO2 prevented much of the foliar damage that would otherwise have been induced by the high O3 concentrations.

Grand Minimum of the Total Solar Irradiance Leads to the Little Ice Age Print E-mail
Written by Habibullo Abdussamatov   
Monday, 25 November 2013 18:02

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 fundamental cause of corresponding alternations of climate variations. At the same time, more long-term variations of the annual average of the TSI due to changes in the shape of the Earth's orbit, inclination of the Earth's axis relative to its orbital plane, and precession, known as the astronomical Milankovitch cycles, together with the subsequent feedback effects, lead to the Big Glacial Periods (with the period of about 100,000 years).

Modern Growth Trends of Earth's Forests Print E-mail

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 about 50,000 entries, which database, in their words, "contains all available archived and published data." And in doing so, they discovered that over the period 1961-1998, "aboveground wood, roots, and green parts increased by 4%, 21%, and 33%, respectively," such that "the total carbon density of the living biomass stock of the Russian forests increased by ~9% from 4.08 to 4.44 kg C m-2." In addition, they report there was an "increase in the area of the Russian forests (from 695.5 x 1010 m2 in 1961 to 774.2 x 1010 m2 in 1998)," which equates to an increase of about 11%.

Natural and Anthropogenic Perturbations in Cloud Albedo Print E-mail

Thursday, 14 November 2013 22:20

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 same order (but opposite in sign) as that of greenhouse gases." Thus, this summary presents a brief review of a number of scientific papers that address this crucial issue.

Plant Productivity: Growth Response to C02 When Coupled with Ozone Print E-mail
Written by Staff   
Wednesday, 06 November 2013 19:12

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 by Fowler et al. (1999), who estimated O3 to have been negatively impacting a full quarter of earth's forests at the close of the 20th century, and who calculated it to have the potential to negatively impact fully one-half of the planet's forests by 2100.

Correlation Does Not Equal Causation and Causes Do Not Equal Effects Print E-mail
Written by Lee Gerhard   
Tuesday, 05 November 2013 18:22

Correlation is the easiest method to assign causation for an event, even though it is the least valid method. Take an automobile race, for instance. The last four races were won by blue cars. Blue cars win races. That is an example of correlation driving causation. In reality, Vettel was driving the blue car. He just won the Grand Prix championship for 2013. The color of the car had nothing to do with winning the races. There are frequent correlations that do not identify the causes of events, but politics and media jump on the simplest correlations because they do not require extensive research nor complex analysis.

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 reviews of pertinent studies directed, first of all, at glacial periods, then the singular Holocene, and finally the past few decades.

Medieval Warm Period and the World's Oceans Print E-mail

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 the oxygen isotope ratios (?18O) of the white variety of the planktonic foraminifera Globigerinoides ruber, which lives year-round in the upper 25 meters of the northern Sargasso Sea and has a relatively constant annual mass flux and shell flux to the sediments. Calibrating these data against temperature and salinity data obtained at Ocean Station "S" (32°N, 62°30'W) over the prior 42 years, he first determined that "temperature accounts for about two-thirds of the isotopic signal, whereas salinity accounts for one-third." And based on these results, he calculated sea surface temperatures (SSTs) of the prior three millennia, after which he "stacked the temperature proxy data from the two subcores by averaging results in 50-year bins," obtaining the results below.

The Positive Externalities of Carbon Dioxide Print E-mail
Written by Craig D. Idso, Ph. D.   
Monday, 21 October 2013 00:00

Advancements in technology and scientific expertise that accompanied the Industrial Revolution initiated a great transformation within the global enterprise of agriculture. More efficient machinery and improved plant cultivars, for example, paved the way toward higher crop yields and increased global food production. And with the ever-burgeoning population of the planet, the increase in food production was a welcomed societal benefit. But what remained largely unknown to society at that time, was the birth of an ancillary aid to agriculture that would confer great benefits upon future inhabitants of the globe in the decades and centuries to come. The source of that aid: atmospheric carbon dioxide (CO2).

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. Because of such concern, several researchers have investigated the relationship between temperature, atmospheric CO2, and biospheric productivity across a range of spatial and temporal scales. In this review we examine what has been learned about the subject for locations in Europe.

Climate alarmists have long contended that the Medieval Warm Period (MWP) was not a worldwide phenomenon, primarily because that reality would challenge another of their major claims, i.e., that late 20th-century temperatures were the warmest of the past millennium or more. Thus, it is important to know what has been learned about this subject in different parts of the world; and in this summary attention is focused on Asian countries other than China, Russia and Japan, which are treated individually in other MWP Summaries.

Medieval Warm Period in Australia & New Zealand Print E-mail

Wednesday, 25 September 2013 07:11

Climate alarmists have claimed for quite some time that late-20th-century and early-21st-century global temperatures were so high as to merit the word "unprecedented" when comparing them to temperatures of the past millennium or two; and they also claim that this achievement was both driven and sustained by the carbon dioxide or CO2 released to the air by mankind's burning of fossil fuels such as coal, gas and oil. But to maintain this dual contention, they have been forced to further contend that the well-known Medieval Warm Period was neither hemispheric nor global in scope, but merely confined to the much smaller region surrounding the North Atlantic Ocean. And they have also had to contend that the MWP was never really as warm as it had long been believed to be.

Knowledge of the past is extremely important when it comes to contemplating future climatic possibilities; for what's happened before can clearly happen again. Hence, this summary briefly reviews the history of Canadian droughts with respect to how they varied over the past several centuries in response to significant changes in global air temperature but very little change in the atmosphere's CO2 concentration, which exercise provides some idea of how Canadian droughts might possibly vary in the post-Little Ice Age world that is known as the Current Warm Period.

In the 19th century, British Prime Ministers used to say there were “lies, damned lies, and statistics”. In the 21st century, we may say there are frauds, serious frauds, and IPCC Assessment Reports. Recall, for instance, the notorious graph in the Fourth Assessment Report that falsely indicated that the rate of global warming is accelerating and we are to blame. Using the same statistical dodge, one can show that a sine-wave has a rising trend.

The celebrated mathematician, astronomer and philosopher of science Abu Ali Ibn al-Haytham, or Alhazen, is justly celebrated as the founder of the scientific method. His image appears on Iraqi banknotes and on the postage stamps of half a dozen nations of the ummah wahida. Al-Haytham, unlike Naomi Oreskes, did not consider that consensus had any role in science.

Medieval Warm Period in South America Print E-mail

Was there a Medieval Warm Period anywhere in addition to the area surrounding the North Atlantic Ocean, where its occurrence is uncontested? This question is of utmost importance to the ongoing global warming debate, since if there was, and if the locations where it occurred were as warm then as they are currently, there is no need to consider the temperature increase of the past century as anything other than the natural progression of the persistent millennial-scale oscillation of climate that regularly brings the earth several-hundred-year periods of modestly higher and lower temperatures that are totally independent of variations in atmospheric CO2 concentration. Hence, this question is here considered as it applies to South America, a region far removed from where the existence of the Medieval Warm Period was first recognized.
