Rapid Melting of Ice Sheet in Andes Threatens Regional Water Supplies —
22 Apr 2013 —
More evidence is showing that the world's changing temperatures are prompting record ice melt, putting at risk large ice sheets. Though much of the current focus has been on the massive ice reserves in Greenland and the Arctic, scientists are finding that glaciers high in the mountains, such as in the Himalayas and the Andes, are also receding. A study published in Science documents the rapid changes in an ice cap high in the Andes in Peru, where ice that took 1,600 years to form has melted in just the past 25 years, putting at risk vital water sources for the region.

Increased Carbon Dioxide Levels Damage Coral Reefs —
17 Apr 2013 —
Scientists have been worried about coral reefs for years, since realizing that rising temperatures and rising ocean acidity are hard on organisms that build their skeletons from calcium carbonate. Researchers on Australia's Great Barrier Reef are conducting an experiment that demonstrates just how much corals could suffer in the coming decades. ~~ In the second clip, a climate scientist from California has been conducting an experiment to see whether antacid can boost coral growth.

Climate Change—Rapid, Unpredictable, and Non-Linear Responses —
20 Mar 2013 —
Guy McPherson joins KMO to discuss the prospect of runaway climate feedback loops. McPherson reviews ten major feedback loops and explains why nine of them are already set to enter runaway mode, regardless of any future reductions in manmade greenhouse gases. The sum of these effects will cause a massive climate shift and lead him to believe that human extinction is a real possibility in the not-so-distant future.

As More Polar Ice Melts, More Polar Bears Starve —
15 Feb 2013 —
Polar Bears have long been the poster species for the problem of climate change. As the polar ices becomes less and less each year, the habitat for polar bears and their seal prey shrinks. A new paper in Conservation Letters argues that supplemental feeding may be necessary to prevent polar bear populations from going extinct. Polar bear expert Andrew Derocher explains.

Rogue "Ocean Iron" Activity Disturbs Scientists —

Many scientists were alarmed to hear that a team led by US businessman Russ George performed a kind of wildcat experiment recently, dumping 100 tons of iron-enriched material into the Pacific Ocean. The apparent point of this was to stimulate plankton growth, which would, in turn, lead to increased food for salmon and, possibly, to an increase in carbon uptake into the ocean ecosystem. But according to Dr. Kenneth Coale, scientific understanding of what "iron fertilization" like this can accomplish—or the damage it may do—is lacking.
