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.

Sea Level Rise is Far Worse Than Previously Thought

The world's coastlines with a 6 meter (19+ foot) rise in sea level. NASA

Rising levels of greenhouse gasses are increasing global temperatures and this is causing sea levels to rise. Global warming causes sea levels to rise by melting ice sheets, glaciers, and sea ice; it also causes water to warm and expand. Sea-level rise and resultant flooding may be the greatest challenge facing humanity. Scientists agree that sea levels will rise and much of the most …

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 …

Video Friday: Growing Concern Over Sea Level Rise

growing concern from scientists studying the Greenland and Antarctica ice sheets over the potential for sea level rise

From the Yale Climate Forum. Scientists studying the Greenland and Antarctic ice sheets express growing concern over the fragility and vulnerability of the world’s ice sheets and the potential impact on sea level rise. Researchers in Antarctica are using sophisticated equipment to drill down 500 meters below the ice shelf to measure ice loss, temperature, salinity and speed of melt. In one location measured …
