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.

Thursday, 08 August 2013 22:21

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.

Solar and Planetary Oscillation, Control on Climate Change: Hind-cast, Forecast and a Comparison of the CMIP5 GCMs Print E-mail
Written by Nicola Scafetta   
Wednesday, 17 July 2013 21:36

ABSTRACT Global surface temperature records (e.g. HadCRUT4) since 1850 are characterized by climatic oscillations synchronous with specific solar, planetary and lunar harmonics superimposed on a background warming modulation. The latter is related to a long millennial solar oscillation and to changes in the chemical composition of the atmosphere (e.g. aerosol and greenhouse gases). However, current general circulation climate models, e.g. the CMIP5 GCMs, to be used in the AR5 IPCC Report in 2013, fail to reconstruct the observed climatic oscillations. As an alternate, an empirical model is proposed that uses: (1) a specific set of decadal, multidecadal, secular and millennial astronomic harmonics to simulate the observed climatic oscillations; (2) a 0.45 attenuation of the GCM ensemble mean simulations to model the anthropogenic and volcano forcing effects. The proposed empirical model outperforms the GCMs by better hindcasting the observed 1850-2012 climatic patterns. It is found that: (1) about 50- 60% of the warming observed since 1850 and since 1970 was induced by natural oscillations likely resulting from harmonic astronomical forcings that are not yet included in the GCMs; (2) a 2000-2040 approximately steady projected temperature; (3) a 2000-2100 projected warming ranging between 0.3 oC and 1.6 oC , which is significantly lower than the IPCC GCM ensemble mean projected warming of 1.1 oC to 4.1 oC ; (4) an equilibrium climate sensitivity to CO2 doubling centered in 1.35 oC and varying between 0.9 oC and 2.0 oC.

What impact do global warming, the ongoing rise in the air's carbon dioxide (CO2) content and a number of other contemporary environmental trends have on the atmosphere's methane (CH4) concentration? The implications of this question are substantial, in light of the fact that methane is a more powerful greenhouse gas, molecule for molecule, than is carbon dioxide. We here consider this question as it applies to methane emissions associated with natural vegetation.

On June 25th, President Obama unveiled his plan to reduce what he refers to as "carbon pollution" – the emission of gaseous carbon dioxide into the air that primarily results from the burning of fossil fuels. In discussing the rationale for his plan, the President claims that carbon dioxide, or CO2, "causes climate change and threatens public health" and that "cutting carbon pollution will help keep our air and water clean and protect our kids." Unfortunately, President Obama's statements could not be further from the truth. Far from being a "pollutant," carbon dioxide is the Elixir of Life.
