Comments Off on Scientists dash to explore Antarctic ecosystem hidden by ice for 120,000 years

Scientists are seeking to explore an underwater area previously covered by an Antarctic ice shelf for 120,000 years. Climate change is affecting every corner of the globe and while its challenges are well known, the dramatic changes also open up new opportunities for exploration. The recent breaking away of a trillion-ton iceberg the size of Delaware from Antarctica’s Larsen C Ice Shelf offers scientists a chance to gain a greater understanding of the polar aquatic ecosystem that dwells beneath the ice. Researchers are now in a race against time to study the 2,246 square-mile area before it begins to change. “The calving of [iceberg] A-68 [from the Larsen C Ice Shelf] provides us with a unique opportunity to study marine life as it responds to a dramatic environmental change,” said Kkatrin Linse of the British Antarctica Survey (BAS) in a statement. “It’s important we get there quickly before the undersea environment changes as sunlight enters the water and new species begin to colonize.” Two previous efforts to explore newly exposed Antarctic ecosystems in 1995 and 2002 yielded little in terms of studied life. However, both efforts took five to 12 years after an iceberg’s break before studying the area up close. By then, organisms had begun to occupy space in the newly open habitat.

During their study, the team may encounter such wild Antarctic creatures as the icefish, which creates natural antifreeze within its body to survive in frigid waters, or the bristled marine worm, described by Live Science as “ a Christmas ornament from hell. “ Via Live Science Images via NASA   (1)

Scientists unearth potential evidence of climate change 2,400 feet beneath Antarctic ice sheet

Comments Off on Scientists unearth potential evidence of climate change 2,400 feet beneath Antarctic ice sheet

A research team on the coast of West Antarctica has uncovered evidence that could indicate the effects of climate change deep beneath one of most isolated parts of the ocean. Earlier this month, a team of 40 scientists, ice drillers, and technicians celebrated the accomplishment of breaking through a 2,400 foot-thick ice sheet with a video probe that revealed pebbles on the sea floor, which normally wouldn’t be found at that depth.

VIDEO: Do Polar Bears Eat Fast Food Too?

Comments Off on VIDEO: Do Polar Bears Eat Fast Food Too?

A polar bear caught chomping on a goose egg. No fries with that, though. We humans have been seeing a trend towards slow food, but it looks like polar bears may be headed in the opposite direction. Joshua Davis, Michael Kirby Smith and James Gorman recently made a fascinating video for the New York Times about how scientists in the Western Hudson Bay have observed polar bears gorging themselves on easy-to-grab goose eggs (with some bears eating 200-300 nests of eggs in a 96 hour period) instead of partaking in their traditional meal of seals. But what does this dining drift mean in terms of climate change? Read on for the full video. Read the rest of VIDEO: Do Polar Bears Eat Fast Food Too?

Facebook Unveils Plans for Solar-Powered Internet Drones as Big as 747s

Comments Off on Facebook Unveils Plans for Solar-Powered Internet Drones as Big as 747s

Yael Maguire , the engineering director at Facebook ‘s Connectivity Lab, has revealed further details about the social media giant’s plans to expand internet access to communities worldwide. In order to achieve global connectivity, the company has been discussing using drones, or planes as they prefer to call them, that will constantly circle in the skies . In conversation with Mashable CEO Pete Cashmore, Maguire stated the planes would be “roughly the size of a commercial aircraft, like a 747.” As astounding as that revelation is on its own, it also raises regulatory questions. Not only are there unresolved issues around launching and airspace controls, but with an anticipated need for thousands of planes, the company says it is impractical for one person to control only one plane at a time as current legislation requires.

Comments Off on A Junior Polar Vortex is Returning to the Eastern US

Just when you thought it was safe to go outside, the dreaded polar vortex is about to rear its ugly head once again. This week, a pocket of cool air is making its way from the Gulf of Alaska, across the Great Lakes and along the East Coast in a chilling (get it?) replay of January’s bone-deep freeze. The normally-sweltering July heat will be pummeled down by cold Alaskan air and rainstorms that might have some people reliving the January vortex all over again.

Comments Off on IBM and DARPA’s Ultra-High-Speed Digital Data Link Sets Energy Efficiency Record

The supercomputers of the future will be capable of amazing feats such as modeling global climate scenarios , running molecular-level simulations of cells, and designing nanostructures. In order to for these “exascale computers” to operate, they will need to be able to run an enormous amount of data quickly while keeping power consumption under control. Scientists at IBM in conjunction with DARPA have created an ultra-high-speed prototype optical link that sets a new energy efficiency record. The researchers are set to describe their invention at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) being held in Anaheim, CA from March 17-21.

US Forest Service Confirms That Climate Change is Killing Alaskan Trees

Comments Off on US Forest Service Confirms That Climate Change is Killing Alaskan Trees

As confirmed by researchers from the U.S. Forest Service , climate change is killing off the mighty yellow cedar — a valuable tree native to the Alaskan Panhandle. On average, the yellow cedar can live more than 1,000 years, resisting bugs, rot and protecting itself from injury. However, mighty as they may be, it is their shallow roots make them vulnerable to freezing when the soil atop the roots is not insulated by snow. With over half of a century of decreased snowfall, nearly half a-million acres in southeast Alaska, plus another 123,000 acres in British Columbia of yellow cedar are now dead. Luckily for the yellow cedar, specialist are now searching for a location where the their shallow roots can thrive — but this situation also speaks to a larger issue. As it’s clear that the devastation of the yellow cedar is one of the negative side effects of climate change, it’s also indicative of how  climate change will alter how we manage forests.

Comments Off on This Adorable Baby Polar Bear Needs a Name!

Say “hi” to the new and extremely adorable baby polar bear who was born at the Toronto Zoo just a couple of days ago. The zoo’s staff couldn’t come up with a name for the newborn, so instead of racking their brains, they are hosting a contest through Facebook instead! Engaging kids and adults in the naming process is a great way to get them excited about animals, but we’ve got to say, we think this baby bear could do better than the already suggested Snowball, Q-Tip, Playie or Aspen. So go on and think of a good name — but bear in mind, this fluffy little bundle seems to be a male!
