In a break from their usual business of overthrowing South American governments, covering up alien landings, and broadcasting coded messages through my fillings, the CIA has revived a program that teams up spies and scientists for the study of climate change. Through the program, scientists get access classified images of the polar ice caps, as well as the chance to pick the targets of off-duty spy satellites.
A massive iceberg twice the size of Manhattan is headed for Australia's southwestern coast, threatening shipping lanes in the Pacific.
The "superberg," called B17B, is roughly 1,000 miles off the coast of Australia and headed for warmer waters, where it will likely break up into many small pieces.
In 1985, scientists from the British Antarctic Survey found a giant hole in the ozone layer of Earth's atmosphere over the South Pole. This discovery prompted a largely successful international effort to ban CFCs, the chemicals largely responsible for man-made thinning of the ozone layer.
In the 30 plus years since scientists started using satellites to track the area of the Arctic ice cap, the size of the ice pack has gotten smaller and smaller. However, new data from NASA's IceSAT satellite shows that the ice has been melting faster than anyone predicted.
A 25-mile-long ice bridge that linked the Wilkins Ice Shelf to Charcot Island on the Antarctic Peninsula has collapsed. NASA satellite imagery shows that the bridge's disintegration occurred sometime between March 31 and April 6. Scientists had been keeping a close eye on the bridge since last March, anticipating its collapse following dramatic changes that have taken place on the Wilkins Shelf in recent years.
To predict the unpredictable: That's the goal of a new government initiative on abrupt climate change. As the atmosphere reels under the influence of greenhouse gases, scientists fear the growing risk of dramatic environmental changes occurring within decades—far faster than current computer models predict. Ice sheets might not just melt but collapse wholesale, rapidly raising sea levels and flooding entire coastlines. Regional rain shortages could cause megadroughts that choke our water and food supply.
