Mount Everest Glaciers May Disappear by 2100 Rising Emissions
Posted by Nature World News: None Given on May 27th, 2015
Nature World News: Mount Everest's glaciers may disappear almost entirely by the year 2100 if greenhouse gas emissions continue to rise, a new study warns.
"The signal of future glacier change in the region is clear: continued and possibly accelerated mass loss from glaciers is likely given the projected increase in temperatures," Joseph Shea, a glacier hydrologist at the International Centre for Integrated Mountain Development (ICIMOD), Kathmandu, Nepal, who led the study, said in a statement.

Major Antarctic Ice Shelf May Disappear by 2020
Posted by Nature World News: None Given on May 19th, 2015
Nature World News: With climate change heating things up, and the Earth's poles rapidly melting, it should come as no surprise that a major Antarctic ice shelf may completely disappear by 2020, according to a new NASA study.
The last remaining section of the Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening, flowing faster, and becoming more and more fragmented as well as developing large cracks. This, plus the fact that two of its tributary glaciers are also flowing faster and thinning...
Massive Glacier Melt Pouring into Gulf of Alaska
Posted by Nature World News: None Given on March 21st, 2015
Nature World News: The collective freshwater discharge of this region is more than four times greater than the mighty Yukon River of Alaska and Canada, and half again as much as the Mississippi River. While scientists had indeed noticed this runoff, until now they had no idea the magnitude of its impact.
If all this mountain rain, snow and glacial ice melt empties into the Gulf of Alaska, it would create the sixth largest coastal river in the world if it emerged as a single stream, researchers say.
"Freshwater...
Is Warming Arctic Behind Our Heat Waves?
Posted by Nature World News: None Given on March 16th, 2015
Nature World News: That's at least according to a study recently published in the journal Science, which details how Arctic warming is essentially putting the brakes on atmospheric circulation in mid-latitudes, leaving North America and Europe with uncharacteristically strong heat waves.
For instance, in 2003, west Europe was slammed with a wave that was associated with the deaths of nearly 70,000 people (heat stroke, wild fires, etc). In 2010, Russia was then affected by one that lasted a stunning six weeks, grave...
The Arctic’s Ponds Are Disappearing Even As the Region Melts
Posted by Nature World News: None Given on March 14th, 2015
Nature World News: New research has revealed that the Arctic is losing its ponds, with the important habitats shrinking more every day. This may seem like a strange revelation for some, as past research has revealed that the Arctic continues to melt in the wake of climate change. Wouldn't more melt water mean more ponds? Now, a pair of researchers explain what's really going on.
"Plants are taking over shallow ponds because they're becoming warm and nutrient-rich," Christian Anderson, a postdoctoral fellow at the...
Coral Bleaching Event: Worst in Decades
Posted by Nature World News: None Given on October 7th, 2014
Nature World News: Scientists are frantically monitoring Hawaii's unusual windless coast, finding that elevated sea surface temperatures are severely stressing corals near the shoreline, causing a major coral bleaching event that's even more intense than one seen two decades ago.
"Unfortunately, we are seeing evidence of wide-spread bleaching in shallow, near shore waters of windward Oahu," Frazer McGilvray, the administrator of the Division of Aquatic Resources (DAR) Coral Rapid Response Team, said in a recent...
Great Lakes Break the Ice after Record-Long 7 Months Frozen
Posted by Nature World News: None Given on June 12th, 2014
Nature World News: Most of the United States is gearing up for the fast approaching summer months, traces of the icy winter far behind them, but the Great Lakes are just thawing out after a record-breaking seven months of being frozen.
The NOAA declared all the Great Lakes officially ice-free Wednesday morning after more than 80 percent of its surface was encrusted with ice for seven months - an occurrence that hasn't happened since the 1970s, according to Live Science.
Lake Superior, the deepest, largest and...
Farmed Salmon Threaten Wild Salmon Gene Pool
Posted by Nature World News: None Given on March 10th, 2014
Nature World News: Sterilizing farmed salmon is a good way to conserve the wild salmon gene pool, researchers say.
According to University of East Anglia researchers, farmed salmon are genetically different than wild salmon. However, they are just as fertile as their wild counterparts, meaning that they can invade wild salmon territory.
Millions of farmed salmon escape into the wild and they could deplete the salmon gene pool by mating with the wild population, researchers caution.
"Around 95 per cent of all...
Mangroves in Florida Expanding Due to Climate Change
Posted by Nature World News: None Given on December 31st, 2013
Nature World News: Fewer cold snaps in Florida are helping mangroves extend their territory, according to a new study. Mangroves thrive in warm, salty areas and are known to form complex ecosystems. Their presence in the Sunshine State was limited due to freezing temperatures during winter. However, from the past few years, there has been a decline in the number of days that see temperatures dipping below negative 4 degrees Celsius (25 degrees Fahrenheit). Fewer cold days have led mangroves to getting a foothold...
Large Freshwater Reserves Buried Beneath Oceans
Posted by Nature World News: None Given on December 6th, 2013
Nature World News: Australian researchers have found large reserves of freshwater beneath oceans.
Water scarcity is growing by the day. Previously, other researchers had estimated that rising global temperatures would leave 500 million or more people without access to drinking water. The new research shows that humans might benefit from half a million cubic kilometres of (120,000 cubic miles) water from seabed on continental shelves.
The freshwater reserves have been found off the coast of Australia, China, North...
