Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...

Study on Jakobshavn Isbrae supports growing evidence that calving glaciers are particularly sensitive to climate change Large, marine-calving glaciers have the ability not only to shrink rapidly in response to global warming, but to grow at a remarkable pace during periods of global cooling, according to University at Buffalo geologists working in Greenland. The conclusion stems from new research on Jakobshavn Isbrae, a tongue of ice extending out to sea from Greenland's west coast. Through...

Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels. Scientists have shown for the first time that the terrain beneath glaciers influences how much glacier melt contributes to fluctuations in sea levels. Researchers say the study will improve their understanding of how ice sheet movements have affected sea...

The last glacial maximum, which occurred 21,000 years ago, effects the current distribution of European scarab dung beetles; according to CSIC research, these results could help understanding the consequences of current climate change The study, published yesterday in the journal Ecology Letters, analyzed the species richness and the structure of their communities throughout the different regions of the European territory from the Ural Mountains to the Iberian Peninsula. The selection of this...

Finds that rocks used as key geologic evidence were formed deep within Earth millions of years after the ice age ended There's a theory about how the Marinoan ice age"”also known as the "Snowball Earth" ice age because of its extreme low temperatures"”came to an abrupt end some 600 million years ago. It has to do with large amounts of methane, a strong greenhouse gas, bubbling up through ocean sediments and from beneath the permafrost and heating the atmosphere. The main physical...

A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate. A paper based on the research, co-authored by Professor Grant Bigg, Head of the University of Sheffield's Department of Geography, his PhD student Clare Green, and Dr Mattias Green, a Senior Research fellow at Bangor...

Cooling trend could be on the way unless thwarted by greenhouse gasses There's an old saying that if you don't like the weather in New Mexico, wait five minutes. Maybe it should be amended to 10,000 years, according to new research. In a letter published recently in the journal Nature, Los Alamos National Laboratory researchers and an international team of scientists report that the Southwest region of the United States undergoes "megadroughts""”warmer, more arid periods lasting...

A set of maps created by the University of Sheffield have illustrated, for the first time, how our last British ice sheet shrunk during the Ice Age. Led by Professor Chris Clark from the University´s Department of Geography, a team of experts developed the maps to understand what effect the current shrinking of ice sheets in parts of the Antarctic and Greenland will have on the speed of sea level rise. The unique maps record the pattern and speed of shrinkage of the large...

Russian scientists are set to pierce through Antarctica's frozen surface to reveal the secrets of an icebound lake that has been sealed deep there for the past 15 million years. Alexei Turkeyev, head of the Russian polar Vostok Station, told Reuters by satellite phone that scientists have "only a bit left to go." His team has been drilling for weeks in a race to reach the lake -- buried 12,000 feet beneath the polar ice cap -- before the end of the brief Antarctic summer. With the...

About 450 million years ago, Earth suffered the second-largest mass extinction in its history"”the Late Ordovician mass extinction, during which more than 75 percent of marine species died. Exactly what caused this tremendous loss in biodiversity remains a mystery, but now a team led by researchers at the California Institute of Technology (Caltech) has discovered new details supporting the idea that the mass extinction was linked to a cooling climate."While it's been known for a long...
