John Fasullo's trying to get some of the uncertainty out of predicting climate change. He says many of our current models aren't accurate, and are being used to under-represent the consequences of our warming planet.
Ask Jennifer Francis about Hurricane Sandy and she'll point north. Ask her about this summer's midwestern drought, she'll point north, all the way to the Arctic. She's linked Arctic ice melting with fluctuations in global weather.
We're intimately familiar with the five basic senses: sight, smell, taste, touch and hearing. But what if there were a sixth, or seventh? An English scientist is trying to research how technology can give us additional senses.
Hurricane Sandy roared ashore in New York just two weeks ago, destroying the homes of the wealthy and the poor alike. Elliott Sclar, from Columbia University's Earth Institute, says that will open the door to discussions of future land-use made critical by climate change.
In the world of risk management, the probability of disaster is often expressed as a percentage. But that's not sufficient, scientists say now. And they've turned to an area of California, the Sacramento-San Joaquin Delta, to explain just how badly current models work.
Anyone who owns a dog knows that each one is a little different, with a distinctive personality. At the Clever Dog Lab at the Veterinary University of Vienna, scientists are trying to figure out where that personality comes from -- and how it can be tapped.
Scientists are experimenting with rebuilding oyster reefs off the coast of New York City. One writer suspects that if these structures had been in place, Hurricane Sandy's massive storm surge would have been greatly reduced.
Getting a barrel of oil out of the ground takes energy. Years ago, you could get 100 barrels of oil out of the ground with just one barrel of oil spent. Now, it's more like 20 to one, or even five to one. That compares favorably with renewable energy sources -- but it all depends on how things are counted.
Imagine getting your yogurt from a little ball with an edible skin. Or your ice cream. How about your soda coming from a vending machine not in a recyclable can, but rather with a peel you can bite right into. It's closer to reality than you might think.
Astronauts on the International Space Station celebrated Halloween Wednesday with some treats, but before long it was back to the tricks, keeping the ship running and monitoring Earth, including the progress of post-Hurricane Sandy.
