ice shelf, definition of

A thick mass of ice extending from a polar shore. The seaward edge is afloat and sometimes extends hundreds of miles into the sea.

• Complete ice shelf collapse in Antarctic is a scary signal
  What’s cold, as big as Rome and should be firmly rooted in Antarctica? The Conger ice shelf, which collapsed in mid-March due to record high temperatures.[...]
• Claim: Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly
  Some other researchers suggest that ice cliffs in Antarctica might not collapse as quickly as those in Greenland. But given their size and current rates of warming – far faster than in the historic record – what if they instead collapse more quickly?
• Canada's last Arctic ice shelf has collapsed
  The Milne Ice Shelf, the largest remaining intact ice shelf in Canada, has collapsed. According to researchers studying the Milne Ice Shelf, the ice shelf collapsed in just two days at the end of July and lost about 40% of its area. This ice shelf sits...
• Antarctica's newest iceberg may destabilize the entire ice shelf
  For eighteen months, scientists and concerned citizens waited for a giant iceberg to break off the Larsen C ice shelf in Antarctica. On July 12, the highly-anticipated event finally occurred. Because the iceberg, named A68, was predominantly submerged...
• Fractured Antarctic ice sheet will create one of the largest icebergs ever recorded
  Due to global warming and rising temperatures, glaciers are slowly melting - and, in some cases, breaking apart. A massive 8-mile crack is steadily growing along Antarctica's Larsen C Ice Shelf - and when it splits, the resulting iceberg will be around...

• Antarctic ice shelf will disappear within the next few years, says NASA
  The rest of the last piece of one of Antarctica’s huge ice shelves will be gone within the next few years, according to NASA. There is a remnant of the Larsen B Ice Shelf, which has been around for the last 10,000 years that was the main focus of the
• Antarctica’s Mighty Pine Island Glacier has Reached an Irreversible Melting Point
  An international team of scientists has concluded that Antarctica's mighty Pine Island Glacier has likely reached a tipping point in which the melting is irreversible even if global warming is reversed...
• New York City-Sized Iceberg Breaks Free of Antarctica, Could Threaten International Shipping Lanes
  Earlier this week, NASA released satellite images of a 70,000-hectare iceberg breaking free of Antarctica’s Pine Island Glacier and floating adrift in the Southern Ocean...
• Claim: atmosphere heats the oceans, melts Antarctic ice shelf
  From Penn State Underlying ocean melts ice shelf, speeds up glacier movement Warm ocean water, not warm air, is melting the Pine Island Glacier’s floating ice shelf in Antarctica and may be the culprit for increased melting of other ice …...
