Crucial new information about how the ice ages came about

Posted by External 6 hours 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 6 hours 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

Seasonal Arctic summer ice extent still hard to forecast, study says

Posted by External 21 days ago General
http://feeds.sciencedaily.com — Scientists analyzed 300 summer Arctic sea ice forecasts from 2008 to 2013 and found that forecasts are quite accurate when sea ice conditions are close to the downward trend that has been observed in Arctic sea ice for the last 30 years. However, forecasts are not so accurate when sea ice conditions are unusually higher or lower compared to this trend. Read More
