Has Antarctic Sea Ice Expansion Been Overestimated?

European Geosciences Union (EGU) New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a...

National Snow and Ice Data Center Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage — a direct shipping route from Europe to Asia across the Arctic Ocean — to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and University...

Winter Ice Is On The Decline Across Alaskan Lakes
2014-02-03 10:22:48

Brett Smith for redOrbit.com - Your Universe Online According to a new study from the European Space Agency, ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar images in the study, which was published in The Cryosphere, show how shifts in our climate are affecting high-latitude regions. [ Watch the video: Monitoring Lake Ice ] Alterations in air temperature and winter precipitation over the last 50 years have affected the timing,...

Arctic Sea Ice Minimum For 2013 Sixth Lowest On Record
2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

2013 Ice Melt Will Not Be Record Year Despite Continuing Downhill Trends
2013-08-23 10:06:14

[WATCH VIDEO: Summer Arctic Ice Retreat 2013] Lee Rannals for redOrbit.com - Your Universe Online Arctic sea ice is reaching its annual "minimum" melt for the summer, but NASA says this year's low will unlikely be breaking any records. Last year, Arctic sea ice melted to a record low, making it the largest summer melt since satellites began measuring the process in 1979. This year's melt is beginning to reach its minimum now, and even though it’s not going to catch any records,...

NASA's Operation IceBridge Mission Contributes To New Map Of Antarctica
2013-06-06 09:26:57

NASA A new dataset called Bedmap2 gives a clearer picture of Antarctica from the ice surface down to the bedrock below. Bedmap2 is a significant improvement on the previous collection of Antarctic data–known as Bedmap–that was produced more than 10 years ago. The product was a result of work led by the British Antarctic Survey, where researchers compiled decades worth of geophysical measurements, such as surface elevation measurements from NASA's Ice, Cloud and Land Elevation...

Decline In Snowfall Has Negative Impacts On Plants, Animals
2013-05-07 19:29:15

Lee Rannals for redOrbit.com — Your Universe Online Plants and animals that thrive in deep snowfall seasons are having a tough time in recent years as less and less snow drops down its blanket. Scientists writing in the journal Frontiers in Ecology and the Environment say the gradual decay of the Northern Hemisphere's snowfall is having an impact on life that depends on it. The seasonal microenvironment that relies on snowfall, known as "subnivium," has an effect on everything...
