Observed Climate Change and the Negligible Global Effect of Greenhouse-gas Emission Limits in the State of Utah Print E-mail

In this report, we review the long-term climate history of Utah and find little in the way of evidence that the greenhouse gas build-up in the atmosphere has much altered Utah’s climate. While statewide average temperatures have generally appeared to have risen in Utah over the past 100 years, much of this rise can be attributed to the timing of decadal oscillations of sea surface temperature patterns in the Pacific Ocean. Further, there is evidence that the state’s temperature record may contain non-climatic influences—such as land use changes, instrument changes, and improper instrument siting—which together add a warming bias to the state’s long-term temperature history, making it seem like the temperature has been increasing more than it actually has been.  In any case, there has been no overall temperature rise during the past 20 years.

Experimental Artifacts of Free-Air-C02-Enrichment (FACE) Studies Print E-mail
Written by Staff   
Tuesday, 24 February 2015 09:21

In a provocative paper they entitled "Food for Thought: Lower-Than-Expected Crop Yield Stimulation with Rising CO2 Concentrations," Long et al. (2006)1 suggested that future increases in crop production caused by the fertilization effect of the atmosphere's rising CO2 concentration may be only half as large as what had long been believed would be the case, due to confounding influences they claimed were inherent in all experimental assessments of the growth-promoting effects of atmospheric CO2 enrichment except those employing Free-Air CO2- Enrichment or FACE technology. Quite to the contrary, however, there is a strong possibility that just the opposite could well be true, i.e., that future increases in crop production caused by the aerial fertilization effect of the atmosphere's rising CO2 concentration may well be twice as large as what FACE experiments suggest.

The Extinction Risk for Stationary Plants Print E-mail

In addition to migrating to more suitable locations, Earth’s plants have other ways of successfully responding to various pressures that might otherwise lead to their extinction. The “acid test” for any extinction hypothesis is to examine what appears to be happening - or what appears to actually have happened - in the real world, which is what is done here with respect to studies of plants that are fighting to survive under experimental settings or real-world locations where they periodically face various threats to their survival.

Forest Growth Responses to Increasing Temperatures Print E-mail
Written by Staff   
Thursday, 29 January 2015 00:00

It has been claimed that CO2-induced global warming will be so great and so rapid that many of Earth’s trees will not be able to migrate towards cooler regions (poleward in latitude or upward in altitude) rapidly enough to avoid extinction (Woodwell, 1989; Overpeck et al., 1991; Dobson, 1992; Root and Schneider, 1993; Dyer, 1995). This prediction is based on the assumption that tree growth rates rise from zero at the cold limit of their natural ranges (their northern boundaries in the Northern Hemisphere) to a broad maximum, after which they decline to zero at the warm limits of their natural ranges (their southern boundaries in the Northern Hemisphere). Loehle (1998)1, however, convincingly demonstrated that this assumption is only half correct: it properly describes tree growth dynamics near a Northern Hemispheric forest’s northern boundary; but it is an inaccurate representation of tree growth dynamics near such a forest’s southern boundary.

Was 2014 the Warmest Year on Record? No, It Wasn't... Print E-mail

Nature trumpets “2014 was the hottest year on record,” citing the Japan Meteorological Agency, the World Meteorological Organization, and NOAA. However, NOAA and several other principal terrestrial temperature datasets – which are anyway subject to measurement, coverage and bias uncertainties and have been repeatedly revised in a questionable fashion over the past year to show ever greater warming rates – have not yet reported their December 2014 values.

Problems with Model Predictions of Species Extinctions Print E-mail

Friday, 16 January 2015 00:00

The world's climate alarmists contend that CO2-induced global warming will lead to numerous extinctions of both plants and animals. Initially, this claim was based solely on models of how they thought Earth's climate behaved in response to increases in various atmospheric greenhouse gases, contending that the increases in temperature predicted to result from projected increases in the air's CO2 content would be so great and occur so rapidly that many species would not be able to migrate either poleward in latitude or upward in elevation rapidly enough to avoid extinction in their attempts to find suitable (i.e., cooler) living conditions.

The Influence of C02 on Plant Antioxidants Print E-mail
Written by Craig Idso, PhD   
Thursday, 08 January 2015 00:00

Environmental stresses induced by exposure to pollutants, drought, intense solar radiation and high air or water temperatures generate highly-reactive oxygenated compounds that damage both terrestrial and aquatic plants. Ameliorating these stresses typically involves the production of antioxidant enzymes that scavenge and detoxify the highly-reactive oxygenated compounds. Hence, when stresses are present, concentrations and/or activities of antioxidants in plants are generally observed to be high; and a good question to ask, therefore, is how atmospheric CO2 enrichment impacts this relationship and what the observed results imply. A number of researchers have done just that, and in this summary we highlight what they have learned.

Climate alarmists predict global warming will increase human death rates, and nary a heat wave occurs but what they are quick to blame any concurrent excess deaths on the high temperatures associated with it. Much more deadly than hot weather, however, is cold weather; yet climate alarmists typically ignore the excess deaths that are caused by low temperatures, even though they are far more numerous than those caused by high temperatures. In the present summary we examine a number of papers investigating the relationship between temperature and human health for various locations in Asia.

As living entities, corals are not only acted upon by the various elements of their environment, they also react or respond to them. And when changes in environmental factors pose a challenge to their continued existence, they sometimes take major defensive or adaptive actions to insure their survival.

Since October 1996 there has been no global warming at all (Fig. 1). This month’s RSS temperature plot pushes up the period without any global warming from 18 years 1 month to 18 years 2 months (indeed, very nearly 18 years 3 months). Will this devastating chart be displayed anywhere at the Lima conference? Don’t bet on it.

Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Few studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several such studies of various marine organisms that challenge the alarming and negative projections of the IPCC on the matter.

FACE Experiments and Grassland Species Print E-mail
Written by Staff   
Saturday, 06 December 2014 18:25

In atmospheric CO2 enrichment experiments, nearly all plants almost always exhibit increases in photosynthetic rates and biomass production when environmental conditions are optimal for growth. Even when conditions are less than favorable (low soil moisture, poor soil fertility, high soil salinity, high air temperature), many plants still exhibit a CO2-induced growth enhancement; and that relative or percentage enhancement is sometimes (more often than not, in fact) greater than what it is under ideal growing conditions. It is sometimes suggested, however, that results obtained from CO2-enrichment experiments conducted in growth cabinets, greenhouses and other enclosures may not reflect real-world plant responses to atmospheric CO2 enrichment due to perturbations in microclimate caused by the enclosures. Thus, Free-Air CO2 Enrichment or FACE technology was developed as a means to enrich the air with CO2 around vegetation while having minimal effects on the surrounding microclimate; and the following paragraphs of this summary document describe the results of some of those experiments that were conducted on various grassland species, many of which were growing naturally in pastures.

Effects of Ocean Acidification on Fish Print E-mail
Written by Staff   
Saturday, 06 December 2014 18:10

As the air's CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, and as more and more carbon dioxide therefore dissolves in the surface waters of the world's oceans, theoretical reasoning suggests the pH values of the planet's oceanic waters should be gradually dropping. The IPCC and others postulate that this chain of events, commonly referred to as ocean acidification, will cause great harm -- and possibly death -- to marine life in the decades and centuries to come. However, as ever more pertinent evidence accumulates, a much more optimistic viewpoint is emerging. This summary examines the topic of the potential impacts of ocean acidification on fish.

Additional Grounds for Rejecting Biofuels Print E-mail

In July of 1987, as described by U.S. Department of Agriculture researchers Idso and Kimball (2001)[1], eight 30-cm-tall sour orange tree (Citrus aurantium L.) seedlings were planted directly into the ground at the Agricultural Research Service's U.S. Water Conservation Laboratory in Phoenix, Arizona, where they were enclosed in pairs within four clear-plastic-wall open-top chambers. Then, in November of that year, the two scientists began to continuously pump ambient air through two of the chambers via perforated plastic tubes that lay upon the ground beneath the trees, while through the other two chambers they began to pump air that was enriched with carbon dioxide to a concentration that was 300 ppm greater than that of the surrounding ambient air, which had an average CO2 concentration of 400 ppm. And thus was born one of the longest atmospheric CO2 experiments ever to be conducted anywhere in the world.

The Global Medieval Warm Period Print E-mail
Written by Staff   
Thursday, 30 October 2014 00:00

Between the 10th and 14th centuries AD, earth's average global temperature may have been warmer than it is today, according to the analyses of Lamb (1977, 1984, 1988) and Grove (1988). The existence of this Medieval Warm Period was initially deduced from historical weather records and proxy climate data from England and Northern Europe. Interestingly, the warmer conditions associated with this interval of time are also known to have had a largely beneficial impact on earth's plant and animal life. In fact, the environmental conditions of this time period have been determined to have been so favorable that it was often referred to as the Little Climatic Optimum (Imbrie and Imbrie, 1979; Dean, 1994; Petersen, 1994; Serre-Bachet, 1994; Villalba, 1994)

Growth Rates of Old Versus Young Forest Trees Print E-mail
Written by Staff   
Thursday, 25 September 2014 15:23

The planting and preservation of forests has long been acknowledged to be an effective and environmentally-friendly means for slowing climate-model-predicted CO2-induced global warming. This prescription for moderating potential climate change is based on two well-established and very straightforward facts: (1) the carbon trees use to construct their tissues comes from the air, and (2) its extraction from the atmosphere slows the rate of rise of the air's CO2 content.

Although simple enough that a child can understand it, this potential partial solution to the putative global warming problem has been under attack for several years by people who seek to address the issue solely on the basis of forced reductions in anthropogenic CO2 emissions (see Pearce, 1999[1]).
