Climate alarmists typically claim that tropical cyclones tend to become both more frequent and more intense as planetary temperatures rise; and as a result, scientists continually strive to develop ever better temporal histories of these particular TC characteristics for various ocean basins around the world. We here summarize what they have learned with respect to such storms in the Indian Ocean.

One of the projected negative consequences of global warming is a concomitant increase in climatic variability, including more frequent hot weather events. It is a relatively easy matter to either substantiate or refute such claims by examining trends in extreme temperatures over the past century or so; because if global warming has truly been occurring at an unprecedented rate over the past hundred years, as climate alarmists claim it has, temperature variability and extreme temperature events should be increasing, according to them. Therefore, this review investigates this issue as it pertains to locations in North America.

In evaluating the climate-alarmist claim that anthropogenic-induced global warming will lead to intensified flooding around the globe, it is instructive to see how flood activity has responded to the global warming of the past century or so, much of which is claimed by climate alarmists to be due to anthropogenic greenhouse gas emissions. In this summary, we thus review several studies of the subject that have been conducted in North America.

Tuesday, 05 June 2012 17:10

Among the highly publicized changes in weather phenomena that are predicted to attend CO2-induced global warming are increases in the frequency and severity of various types of storms. Storms are a concern of the residents of any coastal city, as high winds, water surges and high-energy waves carry the potential for damage via flooding and erosion. It is therefore important to examine the historical records of storms for trends, to see if the so-called unprecedented rise in atmospheric CO2 and temperature of the late-20th and early 21st century has had any measurable effect on such records. The present review addresses this issue as it pertains to the region of Australia and New Zealand.

As the air's CO2 content continues to rise, nearly all of Earth's plants should continue to exhibit increasing rates of photosynthesis and, as a result, increased biomass production. But what about plants that are suffering from various pathogenic diseases? Will they be able to reap the benefits of the many positive effects of atmospheric CO2 enrichment?

Climate Regulation and Dimethylsulfide (DMS) Print E-mail
Written by Staff   
Friday, 01 June 2012 16:04

Dimethylsulfide or DMS is an organosulfur compound with the formula (CH3)2S. It is the most abundant biologically-produced sulfur compound to be found in the atmosphere, being emitted to the air primarily by marine phytoplankton. Perhaps its greatest claim to fame is that several years ago Charlson et al. (1987) discussed the plausibility of a multi-stage negative feedback process, whereby warming-induced increases in the emission of DMS from the world’s oceans tend to counteract the effects of the initial impetus for warming. The basic tenant of their hypothesis was that the global radiation balance is significantly influenced by the albedo of marine stratus clouds (the greater the cloud albedo, the less the input of solar radiation to the Earth’s surface). The albedo of these clouds, in turn, is known to be a function of cloud droplet concentration (the more and smaller the cloud droplets, the greater the cloud albedo and the reflection of solar radiation), which is dependent upon the availability of cloud condensation nuclei on which the droplets form (the more cloud condensation nuclei, the more and smaller the cloud droplets). And in completing the negative feedback loop, Charlson et al. noted that the cloud condensation nuclei concentration often depends upon the flux of biologically-produced DMS from the world’s oceans (the higher the sea surface temperature, the greater the sea-to-air flux of DMS).

With respect to extreme weather events, Dezileau et al. (2011)[1] write that the major question of the day is: "are they linked to global warming or are they part of natural climate variability?" And in regard to the significance of this question, they say "it is essential to place such events in a broader context of time, and trace the history of climate changes over several centuries," because "these extreme events are inherently rare and therefore difficult to observe in the period of a human life." Only then, can claims of increased extreme weather events resulting from CO2-induced global warming be properly evaluated, and several researchers have done just that. The present review examines what they have found with respect to the frequency and/or severity of storms located in and around modern-day France.

Among the highly publicized changes in weather phenomena that are predicted to attend the ongoing rise in the air’s CO2 content are increases in the frequency and severity of all types of storms. As a result, and in an effort to determine if these predictions have any validity, many researchers have examined historical and proxy records in an attempt to determine the validity of this hypothesis. The present review examines what has been learned about storm trends in and around the United Kingdom.

Beyond Biomass: Atmospheric C02 Enrichment and Crop Seeds Print E-mail
Written by Staff   
Wednesday, 18 April 2012 15:21

When dealing with agricultural commodities such as grain crops, seeds comprise the yield; and in such cases, the biomass of one is the biomass of the other. Hence, when looking for effects of elevated CO2 on the seeds of such crops, one is naturally interested in something more than just their final biomass; and there are a number of pertinent papers considering the sources of biomass production, as well as seed properties that go beyond biomass, which we explore in this review.

Interactive Effects of C02 and Phosphorus on Plant Growth Print E-mail
Written by Staff   
Wednesday, 11 April 2012 18:43

Under current ambient conditions, plant growth and development are typically carbon-limited, which is why plants generally exhibit increased growth and biomass production in response to atmospheric CO2 enrichment. Next to carbon, nitrogen is usually the second most limiting nutrient to plant growth, followed by phosphorus. Thus, although it is a less significant component of plant tissues than carbon and nitrogen, phosphorus is still required for successful life-cycle completion in many plant species; and, therefore, it is prudent to investigate aspects of plant phosphorus acquisition and biomass production in response to atmospheric CO2 enrichment when phosphorus concentrations in soils are less than optimal.

Wednesday, 04 April 2012 09:55

Among the many 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 this concern, several researchers have investigated the relationship between temperature, atmospheric CO2, and biospheric productivity across a range of spatial and temporal scales. The present review examines what those researchers have learned, focusing on studies that have addressed this issue for the globe as a whole over both the distant and historic past.

In light of the many recent observations, the prospect of earth’s corals being able to successfully cope with the possibility of further increases in water temperatures, be they anthropogenic-induced or natural, appears more than likely, if not altogether certain. Corals have survived such warmth -- and worse -- many times in the past, including the Medieval Warm Period, Roman Warm Period, Holocene Optimum, as well as throughout numerous similar periods during a number of prior interglacial periods; and there is no reason to believe they cannot do it again, if the need arises.

The EPA is effectively no longer under the control of the US Congress; its allegiance is to the UN and implementation of the policies of Sustainable Development via Agenda 21. It has considerable involvement in the IPCC reports and claims the UN body as a peer reviewed authority, in pursuing ever more rigorous controls of “CO2 pollution”, to bring about the realisation of “environmental governance”.

Holocene Temperature Records show Millennial Scale Peroidicity Print E-mail
Written by Craig Loehle and S. Fred Singer   
Thursday, 22 March 2012 13:10

Past studies have detected an ~ 1500-year climate cycle in various types of Pleistocene geologic or ice deposits. It has been proposed that a 1470-year cycle fits the Pleistocene Dansgaard-Oeschger (DO) oscillations and can be explained by a threshold model with forcing. We use nine temperature reconstructions to see if this cycle exists during the Holocene. All these datasets, except Greenland Holocene data, can be fit by models close to a 1470-year period or are compatible to such a model, or can be fit by cycles near 1200 years, both of which can be related to solar-forcing. These results lend suppor to the non-linear threshold model for initiation of Pleistocene DO events and suggest that this periodic climate cycle has continued into the Holocene, but with reduced magnitude.
