Global Warming Pause? The Answer Is Blowin’ Into the Ocean

Publication: NBC News   Date: February 9, 2014   View Article

For the past 13 years, global surface air temperatures have hardly budged higher despite continual pumping of planet-warming gasses into the atmosphere from the engines of modern life. Does this prove global warming is a giant hoax? No, according to a new study, which says the missing heat is being blown into the western Pacific Ocean by extraordinarily powerful and accelerating trade winds.

“Their acceleration over the last couple of decades is way stronger than you’ve ever seen in a climate model, about twice as strong,” Matthew England, a climate scientist at the University of New South Wales in Sydney, Australia, told NBC News. “This is an unprecedented level of strengthening and it is strong enough that it is actually pushing heat in the Pacific Ocean into the ocean’s interior,” he added.

As the heat is drawn down into the ocean’s interior, cooler water rises to the surface and cools air temperatures. When — it’s not a matter of if, noted England — the winds slacken, the heat stored in the Pacific Ocean will return to the atmosphere, allowing the surface air temperatures to spike higher and “catch up to the original projections of global warming in under a decade.”

Cold-water fish food not adapting to a warming world, study says

Tiny sea creatures that play a big role in the ocean food chain are unable to adapt to warming oceans, according to a new study that may have profound ramifications for fisheries.

The cold-water plankton lives for one year or less. Researchers examined a 50-year dataset from the North Atlantic to determine how this creature and another plankton that thrives in warmer water fared over half a century.

Deep-sea Internet to detect tsunamis, spy on smugglers, and discover oil

The Internet may soon reach into the depths of the world’s oceans and relay real-time information to smartphones everywhere — about everything from drug-smuggling submarines and the location of untapped oil reserves to the approach of a deadly tsunami.

Arrays of scientific instruments already bob on ocean buoys, hitch rides on sea turtles and lay bolted to seafloors. But they communicate with each other and scientists in myriad and often inefficient ways, explained Tommaso Melodia, an electrical engineer at the University of Buffalo in New York who is leading the development of the deep-sea Internet.

Pummeled kite surfer dreams up new way to harvest wave energy

Publication: NBC News   Date: October 11, 2013   View Article

Samuel Etherington first hit the waves with a board and kite in hand, the waves hit back with a bruising vengeance. But in learning to harness their power for his kitesurfing adrenaline rush, he found inspiration to design a next-generation wave energy harvester. The contraption scored him a coveted finalist spot in an engineering design competition and could serve as a viable alternative source of energy to boot.

“The waves would just roll and smash over you and then you would tumble and try to get back up on the board and try again and try again,” the mechanical design student at Brunel University near London told NBC News about his early days kitesurfing. “That then really physically hit home. There is a lot of power to be had here.”

11-year-old designs a better sandbag, named ‘America’s Top Young Scientist’

Publication: NBC News   Date: October 10, 2013   View Article

An 11-year-old boy from Florida has designed a new kind of sandbag to better protect life and property from the ravages of saltwater floods. His invention took top honors at a science fair this week, earning him a $25,000 check and a trip to Costa Rica.

“Living in Florida, I’m keenly aware of hurricanes and saltwater flooding,” the Discovery Education 3M Young Scientist Challenge grand prize winner Peyton Robertson, who is a sixth grader at the Pine Crest School in Ft. Lauderdale, Fla., told NBC News.

$2 million in prizes offered for better tools to monitor ocean acidification

Publication: NBC News   Date: September 9, 2013   View Article

The tools that scientists use to monitor the acidification of the world’s oceans are expected to get a major upgrade, thanks to a $2 million competition aimed at rewarding innovations that lower the cost and improve the accuracy of chemical sensors.

The Wendy Schmidt Ocean Health X Prize, unveiled Monday, is the latest multimillion-dollar prize program conducted by the California-based X Prize Foundation. Past prizes have targeted technologies ranging from commercial spaceflight to energy efficient cars— but the latest prize focuses on an even bigger global issue: climate change.

Warming seas changing what fish are for dinner, study says

Publication: NBC News   Date: May 15, 2013   View Article

Warming oceans are pushing fish toward the poles in search of cooler waters, according to a study that raises new concerns that climate change is robbing the tropics of a primary source of income and nutrition.

Meanwhile, in higher latitudes, data show that trawlers are hauling more warm-water fish out of the ocean – a phenomenon that will change what shows up on menus at locavore restaurants from Cape Town to Tokyo.

“There’ll be changes in the kinds of fish that are available to people who would like to follow that kind of (eating local) strategy,” Michael Fogarty, a fisheries biologist with the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center, told NBC News.
