A huge number, 150,000, of Adélie penguins have disappeared from Antarctica's Commonwealth Bay. A recent study tied the occurrence to a giant iceberg that grounded in the area, isolating the penguins and causing them to starve to death. But critics are challenging that claim, suggesting that the birds relocated, instead.
When ice-bergs calve from a glacier, sometimes they tip back into it and send the glacier bounding backward, causing a glacial earthquake.
There are new factors in why the pre-historic ice sheet that covered Canada may have melted, and how this might affect Greenland and Antarctica.
During the last Ice Age, massive slabs of ice covered much of North America, but new research now shows that calving icebergs resulted in a huge influx of freshwater that increased the production of the greenhouse gas, methane, in tropical wetlands.
A fleet of icebergs is probably not to blame for abrupt episodes of cooling in the North Atlantic over the past 440,000 years, according to new research.
When we think of icebergs, we usually picture the cold, wind-chilled expanses of the Arctic and Antarctic, but new research has shown that these massive slabs of ice once drifted as far south as sunny south Florida.
Massive icebergs once ran aground in Greenland sometime within the last 800,000 years, according to a new study, providing scientists with a new understanding of the dynamics of the Ice Age and the extent of the Arctic ice sheet thousands of years ago.
As the planet continues to warm, with no relief in sight, massive losses of sea ice in Antarctica have left icebergs free to roam for most of the year, and these out-of-control boulders are bashing into shores and killing Antarctic species, new research has found.
