Can Polar Bears Survive Rapid Change in Climate Again?
04.03.2010
A team of scientists was able to determine that the polar bear is a relatively new species that rapidly adapted at a time when the Earth was beginning to warm at the end of an ice age, according to a new study published in the Proceedings of the National Academy…

Glacier Ice Loss in Alaska Overestimated; Rate Nonetheless Doubled over Past 40 Years
04.03.2010
According to a new study featured in Nature Geoscience that recalculates glacier melt in Alaska, previous studies might have largely overestimated mass loss from Alaskan glaciers over the past 40 years. The study shows that Alaskan glacier melts between 1962 and 2006 actually contributed about one-third less to sea-level rise…

Warmer Periods May Be Typical during Transitions between Interglacial and Glacial Eras
04.03.2010
The end of the last interglacial era some 115,000 years ago showed significant climate fluctuations, according to a new study. In Central and Eastern Europe, German and Russian climate researchers were able to find that the slow transition between the two latest glacial eras featured at least two possible warming…

Weak Ice Arches Allowing Sea Ice to Leave Arctic
02.03.2010
Large chunks of ice that clump together to form ice arches spanning the straits that lead out of the Arctic Ocean usually prevent the ice from moving around and fleeing the ocean. In recent years, however, these ice arches have been failing to form. The consequences of the resulting sea…

Giant Iceberg from Mertz Glacier in Antarctica could Affect Ocean Conveyor Belt
26.02.2010
A 2,550 square-kilometer iceberg knocked loose from the Mertz Glacier Tongue in East Antarctica earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers found. The iceberg, which was dislodged by an older one, could disturb the area's exceptionally rich biodiversity.
