Krypton used to accurately date ancient Antarctic ice

Posted by External 13 hours ago General
http://feeds.sciencedaily.com — Scientists have successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating -- a new technique that may allow them to locate and date ice that is more than a million years old. This will allow them to reconstruct the climate much farther back into Earth's history and potentially understand the mechanisms that have triggered the planet to shift into and out o Read More

Crucial new information about how the ice ages came about

Posted by External 4 days ago General
http://feeds.sciencedaily.com — Scientists have discovered new relationships between deep-sea temperature and ice-volume changes to provide crucial new information about how the ice ages came about. The researchers found, for the first time, that the long-term trends in cooling and continental ice-volume cycles over the past 5.3 million years were not the same. In fact, for temperature the major step toward the ice ages that ha Read More

Air temperature influenced African glacial movements at height of last ice age

Posted by External 4 days ago General
http://feeds.sciencedaily.com — Changes in air temperature, not precipitation, drove the expansion and contraction of glaciers in Africa's Rwenzori Mountains at the height of the last ice age, according to research. The results -- along with a recent study that found air temperature also likely influenced the fluctuating size of South America's Quelccaya Ice Cap over the past millennium -- support many scientists' suspicions th Read More
