How Warming Impacts Male Capelin Choice of Spawning Habitat

By Craig Idso

Published June 13, 2013

The fish responds as most any logical creature would. It seeks a cooler location. In short, “the flexible use of spawning habitats under divergent temperature conditions suggests that capelin have a high capacity to respond to and possibly tolerate predicted ocean-climate change”… Read More

The authors of this report identify several model biases that exist, suggesting that it may yet be some time before an accurate representation of future storm tracks can be made… Read More

Effects of Elevated CO2 on Plant Attacks by Herbivorous Insects (11 Jun 2013)
Do the changes in plant characteristics wrought by atmospheric CO2 enrichment help or hurt the plants? According to the four Swiss scientists who conducted this study, “doubling the ambient CO2 concentration had a marked effect on plant colonization by winged aphids particularly when plants were exposed to CO2 for longer periods,” where “elevated CO2 led to a respective 15 and 26% reduction of colonization rates” after a period of 6 and 10 weeks, respectively… Read More

Reassessing the Past Century of Warming in Australia (11 Jun 2013)
Did it warm faster or slower than what was previously believed to have been the case? The authors of this paper conclude that biases “have exaggerated apparent Australian warming.” And when those exaggerations are properly addressed, their analysis suggests that Australia appears to have warmed to a lesser degree over the past century… Read More

Rising Atmospheric CO2: Spurning Drought and Fostering Growth of Greek Island Fir Trees (11 Jun 2013)
The late 20th-/early 21st-century increase in groundwater depletion has likely been responsible for a good deal of the simultaneous increase in the rate of mean global sea level rise over that period… Read More

How Do Non-Specialist Sub-Arctic Mammals React to Warming? (12 Jun 2013)
“Contrary to expectation,” three Swedish researchers report that their modeling of species distributions suggests that (1) “predicted climate change up to 2080 will favor most mammals presently inhabiting (sub)arctic Europe,” and that (2) “no species is predicted to go extinct”… Read More
