A recent article in the Financial Times reproduced on the internet recently by CNBC (http://www.cnbc.com/id/100912062), is predicated on the assumption that there has been a “record decline in Arctic sea ice”. However, the data on sea-ice extent only go back to 1979. And they show the Arctic sea ice declining but Antarctic sea ice increasing, so that the global decline in sea-ice extent is not very great.

We begin our investigation into this subject with the words of Matthews et al. (2005)1, who wrote that "coupled climate-carbon cycle model simulations have identified an important positive feedback between the terrestrial carbon cycle and climate, whereby future carbon uptake declines under anthropogenic climate warming." Such is the conclusion of those who see a bleak future in store for terrestrial biospheric productivity. But is this truly the case?

Medieval Warm Period in the Artic Print E-mail
Written by Staff   
Wednesday, 28 August 2013 16:02

This review begins with the study of Dahl-Jensen et al. (1998)1, who used temperature measurements from two Greenland Ice Sheet boreholes to reconstruct the temperature history of this portion of the earth over the past 50,000 years. Their data indicated that after the termination of the glacial period, temperatures steadily rose to a maximum of 2.5°C warmer than at present during the Holocene Climatic Optimum (4,000 to 7,000 years ago). The Medieval Warm Period (MWP) and Little Ice Age (LIA) were also observed in the record, with temperatures 1°C warmer and 0.5-0.7°C cooler than at the time of their writing, respectively. After the Little Ice Age, they report that temperatures once again rose, but that they had "decreased during the last decades," thereby indicating that the MWP in this part of the Arctic was significantly warmer than it was just before the turn of the century.

Controversy abounds over the temperature history of the earth, particularly that of the past one to two millennia. The original debate was sparked by the papers of Mann et al. (1998, 1999), which challenged the long-accepted view that there was nothing unusual about earth's climatic history subsequent to the inception of the Industrial Revolution; and it prompted the Intergovernmental Panel on Climate Change (IPCC) to disavow their original representation of the temperature history of the Holocene (Houghton et al., 1990), where several periods of time prior to the inception of the Industrial Revolution were depicted as having experienced temperatures that were higher than those of the latter part of the 20th century.

Polar Bears Have Not Been Harmed by Sea Ice Declines in Summer - The Evidence Print E-mail
Written by Dr. Susan J. Crockford   
Thursday, 22 August 2013 12:39

The polar bear biologists and professional activists of the IUCN Polar Bear Specialist Group (PBSG) continue to insist that since 1979 increasingly smaller amounts of Arctic sea ice left at the end of summer (the September ice minimum) have already caused harm to polar bears. They contend that global warming due to CO2 from fossil fuels (“climate warming” in their lexicon) is the cause of this decline in summer ice.

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." And because of the great importance of this complex subject, this summary presents a brief review of a number of scientific papers that address various aspects of this crucial issue.

How We Know They Are Lying Print E-mail
Written by John Brignell   
Tuesday, 13 August 2013 20:38

It is to some extent forgivable when people adopt extreme positions out of misapprehension or delusion. It is quite another matter if they mislead others by deliberate falsehood. Politicians, of course, treat the lie as part of their professional equipment. Indeed, in some circumstances they are obliged to use it (when, for example, telling the truth about the economy would cause a run on the currency). In science, up to recent times, there is no circumstance in which a deliberate falsehood is justifiable. It requires at a minimum being drummed out of one’s learned society.

All that has changed with the rise of authoritarian government.

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, varied from region to region and from time to time; and, therefore, the MWP was manifest differently in different parts of the planet. In this Summary, what occurred in China is reviewed.

Growth Response of Grassland Plants Exposed to Higher Temperatures and C02 Print E-mail
Written by Staff   
Thursday, 08 August 2013 22:13

As the atmosphere's CO2 concentration continues to rise, most plants tend to exhibit increased rates of photosynthesis and biomass production, including those of various grassland ecosystems. This increase in productivity should increase the amount of forage available for grazing animals and possibly reduce the land area occupied by bare soil in certain environments. However, some people claim that global warming will negate the growth-promoting effects of atmospheric CO2 enrichment and actually stimulate the opposite process of desertification. This summary thus seeks to develop an answer to this important question by reviewing published scientific studies of the photosynthetic and growth responses of grassland plants to atmospheric CO2 enrichment when exposed to higher-than-normal temperatures.

Delaware's Future Weather Print E-mail
Written by Paul Driessen and David Legates   
Thursday, 25 July 2013 13:07

During this hot, wet summer, a “national climate expert” recently told Delawareans that they can expect even hotter summers – with a climate like Savannah, Georgia’s – by the end of the century. The culprit, naturally: runaway global warming.

Savannah residents are long accustomed to their climate and, thanks to air conditioning and other modern technologies, are better able to deal with the heat and humidity. Nevertheless, the impact on Delaware will be disastrous, Dr. Katherine Hayhoe claims. Nonsense.

Her forthcoming report promises to be no different than other proclamations that persistently predict dire consequences from climate change – and then present taxpayers with a hefty bill. In this scenario, the State’s Department of Natural Resources and Environmental Control (DNREC) paid $46,000 for her report, presumably to suggest that “independent scholars” support the state’s positions.

The preliminary release of her report reads like the script from a bad disaster movie – think The Day After Tomorrow and An Inconvenient Truth. Like them, it also plays fast and loose with the facts.

Impact of Rising C02 on Agricultural Methane Emissions Print E-mail
Written by Staff   
Thursday, 25 July 2013 13:02

What impact does the ongoing rise in the air's CO2 content have on the atmosphere's methane concentration? The implications of this question are huge, in light of the fact that, molecule for molecule, methane is a much more powerful greenhouse gas than is carbon dioxide. Hence, we here consider this question as it applies to methane emissions associated with agricultural operations.

Interactive Effects of C02 and Water Stress on Agricultural Crop Growth Print E-mail
Written by Staff   
Thursday, 25 July 2013 12:48

As the air's CO2 content continues to rise, nearly all of earth's plants will exhibit increases in photosynthesis and biomass production; but climate alarmists periodically claim that elevated concentrations of atmospheric CO2 will lead to more droughty conditions in many parts of the world and thereby significantly reduce or totally negate these CO2-induced benefits. Therefore, to help determine to what degree this claim has any validity, we here review and summarize the results of numerous CO2-enrichment studies that were designed and conducted in such a way as to reveal the various means by which atmospheric CO2 enrichment may actually help a number of important food crops to successfully cope with this potential problem of more frequent periods of less-than-optimal water availability.

The Logical Case against Climate Panic Print E-mail
Written by The Viscount Monckton of Brenchly   
Thursday, 25 July 2013 12:44

Logic is the heartbeat of all true learning – the soul of the Classics, the Sciences and Religion. Once everyone studied the Classics, to know that in logic there is a difference between true and false; the Sciences, to discern where it lies; and Religion, to appreciate why it matters. Today, few study all three empires of the mind. Fewer study the ordered beauty of the logic at their heart.

Is Private Fraser’s proposition that “We’re a’ doomed!” logical? I say No. G.K. Chesterton once wrote: “When men have ceased to believe in Christianity, it is not that they will believe in nothing. They will believe in anything.” The belief that Thermageddon will arise from our altering 1/3000th of the atmosphere in a century is in-your-face illogical, rooted in a dozen fallacies marked out by Aristotle as the commonest in human discourse.

On the Present Halting of Global Warming Print E-mail
Written by Syun-Ichi Akasofu   
Tuesday, 23 July 2013 18:06

Abstract: The rise in global average temperature over the last century has halted since roughly the year 2000, despite the fact that the release of CO2 into the atmosphere is still increasing. It is suggested here that this interruption has been caused by the suspension of the near linear (+ 0.5 °C/100 years or 0.05 °C/10 years) temperature increase over the last two centuries, due to recovery from the Little Ice Age, by a superposed multi-decadal oscillation of a 0.2 °C amplitude and a 50~60 year period, which reached its positive peak in about the year 2000—a halting similar to those that occurred around 1880 and 1940. Because both the near linear change and the multi-decadal oscillation are likely to be natural changes (the recovery from the Little Ice Age (LIA) and an oscillation related to the Pacific Decadal Oscillation (PDO), respectively), they must be carefully subtracted from temperature data before estimating the effects of CO2.

Evidence of Medieval Warm Period in North America: South of the United States Print E-mail
Written by Staff   
Sunday, 21 July 2013 13:23

Climate alarmists claim that rising atmospheric CO2 concentrations due to the burning of fossil fuels - such as coal, gas and oil - have raised global air temperatures to their highest level in the past one to two millennia. And, therefore, investigating the possibility of the existence of a period of equal or greater global warmth within the past one to two thousand years has become a high-priority enterprise; for if such a period could be shown to have existed at times when the atmosphere's CO2 concentration was far less than it is today, there would be no compelling reason to attribute the warmth of our day to the CO2 released to the air by mankind's burning of the fossil fuels that supplied the power that sustained the Industrial Revolution. Therefore, in this review of the pertinent scientific literature, results of the search for such knowledge are presented for studies conducted within North American countries located south of the southern border of the United States.

Observed climate change in Colorado Print E-mail
Written by Staff   
Sunday, 21 July 2013 00:00

Annual temperature: The historical time series of statewide annual temperatures in Colorado begins in 1895. Over the entire record, there has been an upward trend, which has resulted in temperatures in the early 21st century being about 2ºF warmer than temperatures 100 years ago. Despite this long-term rise however, the record continues to be largely dominated by annual and decadal-scale variability. The run of recent warm years comes on the heels of a period of falling temperatures that extended from the early 1940s through the early 1980s. Previous to then, temperatures warmed rapidly from the 1910s through the 1930s, long before high levels of industrial CO2 emissions. The highest annual average statewide temperature was observed in 1934.
