NASA mission calculates global ice melt and rising sea levels

From 2003 to 2010, NASA satellites systematically measured all of Earth's melting glacial ice--the results added up to 4.3 trillion tons of water and a global sea level rise of half an inch.

Put in perspective, that's enough ice to bury the entire U.S. 1.5-feet deep.

These calculations are detailed in a new study released today by a team of scientists at the University of Colorado. The scientists used satellite measurements from the NASA Gravity Recovery and Climate Experiment (GRACE), which launched in 2002 and focused on how melting ice from glaciers and ice caps … Read more

Possible cataclysm due to melting ice

We have 10 years, folks. And then it's man the lifeboats, or head for the hills. That's the conclusion of James Hansen and five other scientists. They've just published a paper with the Royal Society in England. It says melting ice sheets in Greenland and Antarctic could soon reach a point of no return. The team even says the recent reports from the United Nations' global warming conferences are too conservative in their projections of what could happen.

The paper urges quick and decisive action, including attempts to scrub greenhouse gases from the atmosphere. Hansen is outspoken … Read more

A camcorder for the Atlantis market

With so many products going under water these days, the only thing we can surmise is that people are really taking this whole global warming thing seriously. That would be at least one explanation for the proliferation of gadgets like this waterproof digital movie camera.

Gizmag says the Sanyo VPC-CA6 has a resolution of 6 megapixels and a 5x optical zoom, retailing for around $250. It does take stills as well, but if you're not satisfied with the quality you can try any number of waterproof point-and-shoot cameras. Either way, you can transfer your shots with your waterproof USB device … Read more
