Chill Out… And Fight!

Chinese researchers have found a startling correlation between peaks of warfare in China and cold phases. David Zhang, from the University of Hong Kong, writes in the journal Human Ecology that climate change, and the resulting shortage of ecological resources, could be a trigger for armed conflicts in the future. His research highlights how temperature […]

Plant-Methane Brouhaha Put To Bed

The suggestion that plants may be a prodigious source of the greenhouse gas methane has finally been put to the sword by Dutch scientists. Reporting in New Phytologist, Tom Dueck and co-researchers concluded that methane emissions from plants are negligible and do not contribute to global climate change. The researchers executed a novel experiment that […]

Chromosomal Changes Show Effects Of Climate Change

Researchers from the University of Oregon (UO) have produced the first chromosomal map showing the regions of mosquito chromosomes that are evolving in response to climate change. Identifying the specific genes that control seasonal development in animals should aid in predicting which animals may be in danger from changing climates and help identify emerging disease-carrying […]

Glacier Behavior Confounds Climate Pundits

The behavior of two of Greenland’s largest glaciers underlines the problem in assuming that glacial melting and sea level rise will occur at a steady upward pace, reports a new study inScience. Between 2004 and 2005, the two glaciers in question shrank dramatically and dumped twice as much ice into the sea as had been […]

Lakes Missing Their Ice Cover

Ice cover on many small- and intermediate-sized lakes in the U.S. Northeast and parts of the Midwest will come later than usual this year, a reflection of continuing global warming and a stronger-than-expected El Nino phenomenon, says a University at Buffalo (UB) researcher. Kenton Stewart, a UB professor emeritus of biological sciences, gathers freeze-thaw dates […]

Scientists Slam ExxonMobil’s Global Warming “Disinformation”

The Union of Concerned Scientists (UCS), a nonprofit independent scientific organization formed in 1969, has slammed what it calls ExxonMobil’s disinformation tactics in regard to climate change. The UCS has just released a report that details how ExxonMobil has adopted the tobacco industry’s disinformation tactics (as well as some of the same organizations and personnel), […]

Southern Ocean Could Put Brakes On Warming Trend

Climatologists believe the Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought. The new study, appearing in the Journal of Climate, notes that westerly winds in the Southern Hemisphere have moved southward over the last 30 years. As the winds shift south, they can […]

Plankton Generating Oceanic Cloud Cover

Atmospheric scientists from Georgia Tech have reported that emissions from phytoplankton can dramatically alter cloud formation over oceans, adding a new and important variable into the climate change equation. Reporting their findings in Science Express, the researchers admitted they stumbled upon the phytoplankton-cloud connection accidentally. “While looking at satellite pictures, I noticed that cloud properties […]

Swimming Critters Add New Variable To Climate Confusion

Phytoplankton – the microscopic plants that form the foundation of the marine food chain – generate an astonishing amount of power, report oceanographers from Florida State University (FSU). FSU’s Professor William Dewar has calculated that the little critters generate about five times the annual total power consumption of the human world. He added that the […]

Pleistocene Era Methane Adds To Greenhouse Misery

A Florida State University (FSU) scientist says that as the permafrost in Northern Siberia melts because of climate change, methane frozen there since the Pleistocene era will be released into the atmosphere, further fueling the greenhouse effect. FSU’s Jeff Chanton explained that methane’s contribution to the greenhouse effect is more than 20 times that of […]
