The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. New University of Washington research shows that rising sea surface temperatures in the area of the Pacific Ocean along the equator and near the International Date Line drive atmospheric circulation that has caused some of the largest shifts in Antarctic...

The earliest rocks in our solar system were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience The earliest rocks in our Solar System were more like candy floss than the hard rock that we know today, according to research published today in the journal Nature Geoscience. The work, by researchers from Imperial College London and other international institutions, provides the first geological evidence to support...

New research gives the first accurate estimate of how much faster the Earth's core is rotating compared to the rest of the planet. Previous research had shown that the Earth's core rotates faster than the rest of the planet. However, scientists from the University of Cambridge have discovered that earlier estimates of 1 degree every year were inaccurate and that the core is actually moving much slower than previously believed "“ approximately 1 degree every million years. Their findings...

Paper has implications for oxygen depletion, provides photographic evidence of plumes A new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 tons of gaseous hydrocarbons were emitted into the deep ocean. The authors conclude that such a large gas discharge"”which generated concentrations 75,000 times the norm"”could result in...

Earth's global temperature has been rising gradually over the last decades, but the warming has not been the same everywhere. Scientists are therefore trying to pin down how the warming has affected regional climates because that is what really matters to people, and to adaptation and mitigation strategies. Their efforts, however, had hit a roadblock because the necessary observations of the winds over the oceans were biased. Developing a new method to remove the bias, Hiroki Tokinaga and...

The region of Chile that was rocked by an earthquake last February could be at risk for a larger series of tremors, according to a new study published online by the journal Nature Geoscience on Sunday. The 2010 earthquake, which hit the Maule region of the South American country on February 27, "was not unexpected," according to researchers from Italy's National Institute of Geophysics and Vulcanology. "A clearly identified seismic gap existed in an area where tectonic loading has been...

A blanket of dust and rock debris is apparently shielding some glaciers in the world's highest mountain range from thawing, and varying wind patterns might explain why some are defying a melt. "Our study shows there is no uniform response of Himalayan glaciers to climate change and highlights the importance of debris cover," scientists at universities in Germany and the United States wrote in the study of 286 glaciers. Elsewhere in the Himalayas "more than 65 percent of the monsoon-influenced...

An International research team has discovered that seasonal temperatures in Europe, above all in winter, have been affected over the past 500 years by natural factors such as volcanic eruptions and solar activity, and by human activities such as the emission of greenhouse gases. The study, with Spanish involvement, could help us to better understand the dynamics of climate change. Up until now, it was thought that Europe's climate prior to 1900 was barely affected by external factors, but now...

A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate. The findings are important, researchers say, because they suggest that Arctic warming amplified by the loss of reflectivity could be even more significant than previously thought. The study was published online this week in Nature Geoscience. It was funded...

Collaborating with an international research team, an economic geologist from The University of Western Ontario has discovered how gold-rich magma is produced, unveiling an all-important step in the formation of gold mines. The findings were published in the December issue of Nature Geoscience. Robert Linnen, the Robert Hodder Chair in Economic Geology in Western's Department of Earth Sciences conducts research near Kirkland Lake, Ontario and says the results of the study could lead to a...
