Rising sea temperatures lead to reduction in polar bears since the last ice age

CLIMATE DNA from Greenlandic polar bears shed light on how their numbers have been dramatically influenced by changes in climate over the last several thousand years. Relatively small increases in sea temperature have had big consequences for the polar bear. It is nothing new that polar bears in Greenland are threatened. A study just published […]

Massive iceberg discharges during the last ice age had no impact on nearby Greenland

Findings raise new questions about climate dynamics During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe. These sudden episodes, called Heinrich events, occurred […]
