Greenland's ancient forests shed light on stability of ice sheet
... Researchers analysed ice cores from a number of locations in Greenland, including Dye 3 in the south of the country. From the base of the 2km deep Dye 3 core, they were able to extract what they believe is likely to be...Climate changes are linked between Greenland and the Antarctic
...Even if climate records from Greenland and Antarctic ice cores look different, climate of Artic and Antarctic are directly linked. Investigations of an Antarctic ice core indicate a principle connection between both hemispheres by a 'bipolar seesaw'. Even shorter and weaker temperature changes in the south are connected to fast changes in temperature in the north by change of ocean currents i...Scientists detect seasonal pattern to glacial earthquakes in Greenland, see signs of increase
Seismologists at Columbia University and Harvard University have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly and produce temblors as strong as magnitude 5.1 on the moment-magnitude scale, which is similar to the Richter scale. Glacial earthquakes in Greenland, the researchers found, are most common in July and August, and...Microbes under Greenland Ice may be preview of what scientists find under Mars' surface
A University of California, Berkeley, study of methane-producing bacteria frozen at the bottom of Greenland's two-mile thick ice sheet could help guide scientists searching for similar bacterial life on Mars.... ...Methane is a greenhouse gas present in the atmospheres of both Earth and Mars. If a class of ancient microbes called Archaea are the source of Mars' methane, as some scientists have pr...
