In August 2012, a climate extremist addressed to various skeptical climate researchers what he offensively called “an appeal to you to be reasonable”. Christopher Monckton of Brenchley replied, whereupon the extremist – unable or unwilling to produce a single scientific argument – said he did not wish to pursue the debate further. This paper is an extended version of the reply to the climate extremist.

According to model-based predictions, larger and more intense wildfires will increase as a result of CO2-induced global warming; and as a result, many scientists have begun to search for a link between fire and climate, often examining trends of the past to see if they support the model projections. In the following summary, therefore, we examine what has been learned, starting with studies conducted in North America and ending with the planet as a whole.

Insurance costs related to life and property damages caused by extreme weather events have been steadily rising in the United States and elsewhere; and it is not uncommon for many in the insurance industry and government to place the blame for this development on what they claim are significant increases in the frequencies and intensities of severe weather events, since climate models suggest that these phenomena should be increasing as a consequence of CO2-induced global warming. But is this explanation correct? The following material reviews this question as it pertains to hail storms.

Update on the Latest Climate Change Science: The Natural Occurrence of Extreme Weather Print E-mail
Written by Dr. John R. Christy

Senate testimony of Dr. John Christy, August 2012

It is popular again to claim that extreme events, such as the current central U.S. drought, are evidence of human-caused climate change. Actually, the Earth is very large, the weather is very dynamic, and extreme events will continue to occur somewhere, every year, naturally. The recent “extremes” were exceeded in previous decades.

Storm Trends in Australia and New Zealand? No Evidence That C02 Increases Extreme Weather Print E-mail
Written by Joanne Nova   
Thursday, 02 August 2012 10:48

Get ready — for all the fears of extreme weather coming our way — studies of Queensland, Victoria, the whole of SE Australia, New Zealand, and Perth show that either nothing is changing (there have always been bad storms) or possibly, the weather is better now than it used to be. Where is the evidence to support the claims by alarmists that increasing CO2 will make “extreme weather” more common?

Extreme Temperatures Across the Rest of the Globe Print E-mail

Tuesday, 31 July 2012 12:07

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. In prior summaries we have investigated this issue as it pertains to North America, Europe, and Asia. In the present review, we investigate how it pertains to other locations across the globe.

Climate alarmists warn of all sorts of weather disasters, including droughts, as the Earth recovers from the debilitating chill of the Little Ice Age and begins to experience the more benign temperatures of the Current Warm Period. Does history vindicate them? This question is explored via brief reviews of several papers investigating the occurrence of droughts in Mexico.

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.

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.

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).

Historical Storm Trends in France Print E-mail

Friday, 01 June 2012 15:32

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.
