Eight and a Half Centuries of Snowpack Variations in the Andes of Chile and Argentina

By Craig Idso

Published July 25, 2012

What do they reveal about the nature of snowpack conditions there over the past several decades of supposedly unprecedented global warming? Contrary to the worries of climate alarmists, it would appear that there is nothing unusual, unnatural or unprecedented about the highs and lows of the Andean snowpack… Read More

Biofuels: Forging Ahead Without a Full Understanding of the End Result (24 July 2012)
According to Ridley et al. (2012), “despite rapid growth in biofuel production worldwide, it is uncertain whether decision-makers possess sufficient information to fully evaluate the impacts of the industry and avoid unintended consequences,” because, as they put it, “doing so requires rigorous peer-reviewed data and analyses across the entire range of direct and indirect effects.” And the U.S. research team surmised that such an effort, or set of efforts, had not been made to this point in time… Read More

Ocean Acidification and the Marine Nitrogen Cycle (24 July 2012)
Will future real-world results be as bad as has been predicted by some? In a grand understatement, the authors of this study conclude by saying their findings indicate that “the current hypothesis of the negative impacts of ocean acidification on nitrification, at least for the coastal ocean, might need reevaluation”… Read More

Calculating the Effects of Climate Change and Atmospheric CO2 Enrichment on California (USA) Crop Production (24 July 2012)
Scientists reject experimental observations to go with theoretical model predictions. Very strange? … or only to be expected?… Read More

Extreme Temperature Events Throughout South America (25 July 2012)
In general, over most of South America there has been a decrease in the extremeness of both daily maximum and minimum air temperatures, with the maximums declining and the minimums rising. This finding is very encouraging for that continent’s inhabitants, for cold waves and frost are especially harmful to agriculture, which the author of this paper says is one of the main economic activities in South America. And cold waves and frost days have been on the decline nearly everywhere throughout the continent during the period of 20th-century global warming… Read More

Tropical and Subtropical Birds Expanding Northwards in Texas (25 July 2012)
Whereas climate alarmists see little of hope in warming-induced migrations of species, real-world studies paint a much different picture of the recent and ongoing reorganization of the planet’s many and varied ecosystems… Read More

Recurrent Bleaching and Storms Need Not Spell “the End” for Earth’s Corals (25 July 2012)
Most models predict an increase in the frequency and severity of negative disturbances for coral reefs over the next few decades. It is possible, of course, that those predictions may never come to pass; nevertheless, it is important to consider the natural ability of Earth’s corals to resist or recover from such challenges… Read More
