Latest Research Reveals Troubling Signs of Antarctica Ice Loss, Ocean Warming and Climate Warming Effects at World Heritage Sites

Antarctic ice loss

Antarctica's ice sheets are losing mass more than six-times faster than previously believed and ocean temperatures are rising as much as 40-times faster than the latest U.N. IPCC report estimates. One in four UNESCO natural World Heritage sites are "highly threatened" as a result of climate warming, according to recent research.

NASA Research Indicates Slow, Irreversible West Antarctic Ice Melt

New research from NASA indicates an unstoppable chain reaction of Antarctic ice melt in the Amundsen sea

Bad news for Antarctic ice, but not particularly surprising to scientists Several news headlines this week have heralded the “unstoppable” decline of a major portion of the West Antarctica ice sheet in the Amundsen Sea, eventually disappearing in as little as two centuries. Projections for the complete collapse of the West Antarctic ice sheet range from two hundred to nearly nine hundred years, but what is clear is that …

50 Million Year Old Fossil Clams Shed Light on El Nino and Global Warming

One current climate theory suggests that global warming could result in El Nino conditions becoming permanent as opposed to occurring in prevailing two- to seven-year cycles. New research based on a study of a long-lived species of fossilized clam that lived of the coast of Antarctica indicates that was not the case during the early Eocene, when the Earth was as warm as it's been in the last 65 million years.

Shifting Ocean Currents Drive Accelerating Ice Melt of Antarctic Ice Shelf

Shifting currents are eating away at the Pine Island Ice Shelf

Shifting ocean currents appear to be accelerating ice melt of the Pine Island Glacier Ice Shelf in western Antarctica. According to research published this week in the journal Nature Geoscience, scientists from the Lamont-Doherty Earth Observatory at Columbia University have recorded ocean currents driving at and underneath the ice shelf, carving out an expanding cavity from underneath the glacier, creating a growing impact 50 …
