Periodically, individual scientists and groups of scientists analyze global sets of sea level data to see if there is any indication of a dramatic increase in the mean rate-of-rise of the global ocean surface in response to the supposedly unprecedented warming of the planet over the course of the 20th century and the initial phase of the 21st century, which latter phenomenon the world's climate alarmists claim should be accelerating global sea level rise and leading to catastrophic coastal flooding throughout the world. Hence, we here provide a brief summary of the findings of several such studies that we have reviewed over the past several years.

Antarctic Sea Ice Trends Print E-mail

Noting that Antarctic sea ice may show high sensitivity to any anthropogenic-induced increase in temperature, Watkins and Simmonds (2000)1 analyzed temporal trends in different measures of the sea ice that surrounds Antarctica, using Special Sensor Microwave Imager data obtained from the Defense Meteorological Satellite Program for the nine-year period December 1987-December 1996, in search of the suspected signal. But contrary to what one would expect on the basis of climate model simulations, and especially in light of what climate alarmists of the day described as the unprecedented warming of the past quarter-century, the two scientists observed statistically significant increases in both sea ice area and extent; and when they combined their results with those of the preceding nine-year period (1978-1987), both parameters continued to show increases over that expanded time period. In addition, they found that the 1990s also experienced increases in the length of the sea-ice season.

Effects of Ocean Acidification and Warming on Corals (Laboratory Studies) Print E-mail
Written by Staff   
Thursday, 13 August 2015 18:48

Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Fewer studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several of such studies for coral reefs, as reported in various laboratory-based studies on the topic. Contrary to what is widely assumed and reported, the studies reviewed here collectively reveal that many corals will remain unaffected by rising temperatures and atmospheric CO2 concentrations. Furthermore, in contrast to projections, some will likely experience growth and performance benefits.

Monday, 20 July 2015 19:06

In agricultural enterprises the buildup of soil salinity from repeated irrigations can sometimes reduce crop yields. Similarly, in unmanaged ecosystems where exposure to brackish or salty water is commonplace, saline soils can induce growth stresses in plants that are not naturally adapted to coping with this problem. Consequently, it is important to understand how rising atmospheric CO2 concentrations may interact with soil salinity to affect plant growth; and in the paragraphs that follow, we summarize the results of a number of experiments that were designed to obtain knowledge pertinent to this endeavor.

Atmospheric C02 Enrichment: Boon or Bane of the Biosphere? Print E-mail
Written by Staff   
Wednesday, 01 July 2015 10:45

Is the human-induced increase in the atmosphere’s carbon dioxide concentration good or bad for the earth and its inhabitants? A number of scientists who base their opinions primarily on the predictions of climate models vociferously claim that it’s bad. Other scientists, who base their opinions primarily on real-world weather measurements and historical proxy temperature reconstructions, along with the known positive effects of atmospheric CO2 enrichment on terrestrial plant growth and development, as well as its benign effects on aquatic plants and animals, are equally adamant that it’s good.

Climate Model Inadequacies (Sea Ice) Print E-mail

Near the start of the current century, Holland (2001)1 wrote that with respect to contemporary state-of-the-art global climate models, "some physical processes are absent from the models," while noting that in light of the coarse-resolution grids employed by the models, "some physical processes are ill resolved" and that others are actually "missing from the simulations," which facts led him to question, as he put it, "whether the simulations obtained from such models are in fact physically meaningful." And so it was that he thus went on to conduct his own analysis of the subject, which he designed to determine the difference in model evolution of sea ice cover using a relatively coarse-resolution grid verses a fine-resolution grid, with specific emphasis placed on the presence and treatment of a mesoscale ocean eddy and its influence on sea ice cover.

"Earthworms," in the words of Edwards (1988), "play a major role in improving and maintaining the fertility, structure, aeration and drainage of agricultural soils." As noted by Sharpley et al. (1988), for example, "by ingestion and digestion of plant residue and subsequent egestion of cast material, earthworms can redistribute nutrients in a soil and enhance enzyme activity, thereby increasing plant availability of both soil and plant residue nutrients," as others have also demonstrated.

We begin this brief analysis of the effects of global warming and atmospheric CO2 enrichment on Earth's mammals with a review of the study of Norment et al. (1999)1, who summarized and compared the results of many surveys of mammal populations observed along the Thelon River and its tributaries in the Canadian Northwest Territories from the 1920s through much of the 1990s.

One of the most challenging and important problems facing today's general circulation models of the atmosphere is how to accurately simulate the physics of earth's radiative energy balance. Of this task, Harries (2000)1 wrote that "progress is excellent, on-going research is fascinating, but we have still a great deal to understand about the physics of climate.

Friday, 10 April 2015 00:00

Trees grown in CO2-enriched air nearly always exhibit increased rates of photosynthesis and biomass production, while trees grown in ozone (O3)-enriched air tend to experience the opposite effects. So what happens when both of these trace constituents of the atmosphere increase together? This question is addressed in the present summary with respect to birch trees.

Effects of Ocean Acidification on Marine Crustaceans Print E-mail
Written by Staff   
Wednesday, 01 April 2015 19:54

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. Such optimism is the focus of this summary examining the effects of ocean acidification on crustaceans.

Cyanobacteria-also known as blue-green algae, blue-green bacteria or Cyanophyta (the smallest of which, less than two micrometers in diameter, are typically referred to as picocyanobacteria)- obtain their energy through the process of photosynthesis and are thus important primary producers in many areas of the world’s oceans, as well as significant components of the marine nitrogen cycle. This summary briefly reviews the results of studies that indicate how they may be affected by ocean acidification in a CO2-enriched world of the future, several of which findings challenge alarming negative projections of the IPCC.

Observed Climate Change and the Negligible Global Effect of Greenhouse-gas Emission Limits in the State of Utah Print E-mail
Written by Robert Ferguson   
Monday, 02 March 2015 00:00

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

Saturday, 14 February 2015 11:11

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.
