Insect pests have greatly vexed earth’s trees and shrubs in the past; and they may continue to do so in the future. But the question arises: Will the anticipated increase in the atmosphere’s CO2 content exacerbate, ameliorate or have no effect on this phenomenon? In the paragraphs below, the results of several studies that address this important question… Read More »
Science is supposed to take place by the use of the “Scientific Method” defined in the following way. THE FREE DICTIONARY “The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or… Read More »
I am increasingly concerned that both the climate change problem and its solution have been vastly oversimplified. My research on understanding the dynamics of uncertainty at the climate science-policy interface has led me to question whether these dynamics are operating in a manner that is healthy for either the science or the policy process.[1] I see a growing… Read More »
Will global warming alarmists ever set aside their hypotheses, hyperbole, models and ideologies long enough to acknowledge what is actually happening in the real world outside their windows? Will they at least do so before setting off on another misguided adventure? Before persuading like-minded or naïve people to join them? Before forcing others to risk life and limb… Read More »
Climate models have long suggested that the intensity and frequency of hurricanes or tropical cyclones (TCs) may be significantly increased in response to global warming, as noted by Free et al. (2004), who have written that “increases in hurricane intensity are expected to result from increases in sea surface temperature and decreases in tropopause-level temperature accompanying greenhouse warming,”… Read More »
The effect of elevated atmospheric CO2 concentrations on the water-use efficiencies of trees is clearly positive, having been documented in a number of different single-species studies of longleaf pine (Runion et al., 19991), red oak (Anderson and Tomlinson, 19982), scrub oak (Lodge et al., 20013), silver birch (Rey and Jarvis, 19984), beech (Bucher-Wallin et al., 20005; Egli et… Read More »
You couldn’t make it up. A Russian “Antarctic research vessel” carrying not diligent scientific researchers but 74 taxpayer-funded climate extremists on a junket to help them make up headlines about sea ice melting because of “global warming” finds itself stuck in – er – sea ice. And sea ice in high summer at that. The extremists, as so… Read More »
Over the years, a large number of potential problems associated with various ways of assessing the temperatures of diverse types of land cover have been identified; and several of them are briefly described, with an emphasis on demonstrating the great difficulty of obtaining various surface-specific sets of annual near-surface air temperature which – when combined for the earth… Read More »
It has been claimed that the last decade of the 20th century was the warmest of the past hundred years and possibly the warmest of the entire past millennium (Mann et al., 1998, 1999). It has also been claimed that this observation is a cause for much concern, because the temperatures in question are supposedly so unprecedented. In… Read More »
One of the great horror stories associated with predictions of CO2-induced global warming is that the warming will be so fast and furious that many species of plants will not be able to migrate towards cooler regions – poleward in latitude, or upward in elevation – at rates that are rapid enough to avoid extinction. This claim may… Read More »
