Ice cores: 800,000 years of climate change
CARDIFF U. (UK) — Drill cores taken from Greenland’s vast ice sheets offer the first clue that Earth’s climate is capable of very rapid transitions. Continue…

Glacier’s size runs hot and cold
U. BUFFALO (US) — Calving glaciers are particularly sensitive to climate change, shrinking rapidly in response to global warming and growing at a similar pace during periods of cooling. (more…)

Did cold snap send Vikings packing?
BROWN U. (US) — Why early Viking settlers left Greenland in the 14th and early 15th centuries is still a mystery, but researchers point to plunging temperatures as a possible cause. (more…)

More melting may slow glacier flow
U. LEEDS (UK) — Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers. (more…)

Ancient ice core holds climate future clues
U. COLORADO (US)—An international science team working on the North Greenland Eemian Ice Drilling (NEEM) project has hit bedrock after two summers of work, drilling down more than 1.5 miles in an effort to assess the risks of abrupt future climate change. (more…)

Greenland melt spreads to both coasts
U. COLORADO (US)—Ice loss from the Greenland ice sheet, which has been increasing during the past decade over its southern region, is now making an upward climb on its northwest coast as well. (more…)

Arctic cores signal ‘unique’ climate shift
U. COLORADO (US)—An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change. (more…)

Icy mile leads to climate future
The international North Greenland Eemian Ice Drilling, or NEEM, project begun in 2009 to retrieve deep ice cores from the Earth’s Eemian warm period 120,000 years ago. Atmospheric gases trapped in the ancient ice are expected to help scientists better assess the risks of abrupt climate change as Earth warms in the future. (Courtesy: NEEM Ice Core Drilling Project)

Ice cores show fossil fuels disrupt nitrogen cycle
Scientists extracted a 100-meter-long ice core in Greenland to measure how fossil fuel burning of industrial times has disrupted the global nitrogen cycle.

Fossils suggest murky land-water transition
DUKE (US)—New evidence gleaned from CT scans of fossils may flip the order in which two kinds of tetrapods, four-limbed animals with backbones, moved from fish to landlubber. (more…)
