Arctic Ice Decline in Summer and Winter

The past three years have witnessed a strong decline in summer ice extent in the Arctic, but ice concentration has rebounded in the winters of 2002-2003 and 2003-2004. The winter of 2004-2005 has been different. Besides a strong summer decline in ice concentration, the Arctic now shows a winter decline as well.

PRESS RELEASE: Arctic Sea Ice Decline Continues

The extent of Arctic sea ice — the floating mass of ice that covers the Arctic Ocean — is continuing its rapid decline. Records of the extent of Arctic sea ice extend back to the early 1950s, with the most accurate information starting in 1979, when systematic monitoring with satellites began. Satellite information shows a general decline in sea ice extent of about 8 percent over the last two and a half decades, with the greatest losses in the last three years. This year's sea ice extent is a very close second to the record-setting low of September 2002. See the short official Press Release.

PRESS RELEASE: Antarctic Glaciers Accelerate in Wake of Ice Shelf Breakup

Antarctic glaciers respond rapidly to climate change, according to new evidence found by NSIDC scientists. In the wake of the Larsen B Ice Shelf disintegration in 2002, glaciers in the Antarctic Peninsula have both accelerated and thinned en route to the Weddell Sea. The findings indicate that ice shelf breakup may rapidly lead to sea level rise.

Another Record Minimum for Sea Ice Cover in the Arctic Ocean?

Is the Arctic in for another record low sea ice year? It is starting to look like it. The recently released June 2004 ice extent and concentration are much lower than normal, indicating that annual minimum ice extent and concentration, which occurs in September, is likely to be well below normal. If so, this would be the third year in a row with substantial below-normal ice conditions in the Arctic, an unprecedented event in the 30+ year record of satellite observations of Arctic sea ice.

"The Day After Tomorrow"

The motion picture The Day After Tomorrow may leave many viewers with questions about climate change. In the movie, recent events on Earth's ice sheets and hypothetical future events based on what is known about how climate, oceans, and ice sheets interact, are woven into an exciting but fictitious story about a future climate disaster. The kind of disaster portrayed in the movie is impossible, but the patterns described by the movie have a distant basis in real concepts being discussed by climate scientists, oceanographers, and glaciologists.Read NASA's official response to the movie with additional information from NSIDC.

When the Weather is Uggianaqtuq: Inuit Observations of Environmental Change

NSIDC and the Arctic System Science (ARCSS) Data Coordination Center have released a new multi-media, interactive CD, entitled "When the Weather is Uggianaqtuq: Inuit Observations of Environmental Change." Uggianaqtuq (pronounced OOG-gi-a-nak-took) is a North Baffin Inuktitut word that means to behave unexpectedly, or in an unfamiliar way. From the perspective of many Inuit in the Arctic, the weather has been uggianaqtuq in recent years. In this CD, Inuit from two communities in Nunavut, Canada (Baker Lake and Clyde River), share their observations and perspectives on recent environmental changes. Maps, text, photos, video and music are integrated to help illustrate the changes Inuit have observed in their environment and the impacts on their livelihoods.The CD, authored by Shari Fox Gearheard, is available free of charge. To read more about the project or to order a copy of the CD, please see the the product page.

Antarctic Glaciers Speed Up

Scientists at NSIDC have found that glaciers around the area of the Larsen B Ice Shelf accelerated immediately after it collapsed early in 2002, and are still speeding up.The findings, presented at the AGU Fall 2003 Meeting in San Francisco, support earlier hypotheses that the ice shelf acted as a barrier, slowing the glaciers as they pushed up against the ice shelf, and that removing the barrier would cause the glaciers to speed up. This finding is significant, because it provides a smaller scale preview of what could occur if larger ice shelves, such as the Ross Ice Shelf, were to collapse.

Arctic Sea Ice Low, Second Year in a Row

Last year's sea ice extent and concentration set a new record low in the Arctic. 2003 was a close second, according to remote sensing data from September, when sea ice in the northern latitudes is typically at its lowest, after the summer melt season.The near-record low in 2003, accompanied by sea ice trends showing a steady decline over the last decade, is significant to scientists researching global warming. Not only is sea ice an indicator of possible climate change, but the loss of sea ice itself may further compound the problem. Because ice reflects the sun's energy, less ice means that more of the sun's energy is absorbed, rather than reflected, causing temperatures to rise even further. While sea ice floats, and therefore does not directly contribute to sea-level rise, increasing temperatures around the Arctic may cause areas of the Greenland ice sheet to melt, which could contribute to a rise in sea level.

Largest Ice Shelf in the Arctic Breaks Apart Ellesmere Island

Image courtesy of Mark Serreze/NSIDC. The largest ice shelf in the Arctic, located on the north coast of Ellesmere Island in Canada's Nunavut territory, has broken apart. Researchers at Laval University and the University of Alaska Fairbanks studying the Ward Hunt Ice Shelf say the breakup is likely evidence of ongoing and accelerated climate change in the Arctic.The ice shelf, which acted as a dam to a large freshwater lake, ruptured in August of last year, resulting in the loss of the lake and affecting unique ecosystems. The report is entitled "Break-up of the largest Arctic ice shelf and associated loss of an epishelf lake," and will be published in Geophysical Research Letters.See the NASA Earth Observatory for new images of the ice shelf breakup

Global Glacier Recession Workshop

The National Snow and Ice Data Center hosted a three-day workshop on global glacier recession. The workshop concentrated on evaluating current methods of determining the worldwide recession of mountain glaciers over the last half-century or longer. Recent evidence suggests an acceleration of glacier mass loss in several key regions around the globe. Such glacier changes are significant due to their impact on global sea level rise and water resources. The workshop included a demonstration of GIS-based mapping techniques using satellite imagery and digital databases.

ICESat Mission Launches Successfully

The successful launch of ICESat on January 12, 2003, will provide valuable information on how global climate change affects the polar ice sheets and sea level. The satellite, part of NASA's Earth Science Enterprise, is scheduled to remain in its near-polar orbit for a minimum of three years, measuring changes in ice sheet mass balance as well as sea ice thickness and atmospheric properties. The GLAS instrument on ICESat will provide higher resolution and more precise measurements of the ice sheets than previous missions, greatly improving mass balance models and topographic detail of the ice sheets. NASA's Goddard Space Flight Center designed and built GLAS, and ICESat was assembled by Ball Aerospace in Boulder, CO. The spacecraft will be controlled on-orbit by the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). Laser altimetry and atmospheric lidar data from the mission will be among the products distributed by NSIDC beginning in late summer 2003.For more information on the mission, as well as detailed fact sheets and brochures, please see the ICESat pages.

PRESS RELEASE: Arctic Sea Ice Shrinking, Greenland Ice Sheet Melting, According to Study

The floating cover of sea ice over the Arctic Ocean shrank to unprecedented low levels in the late summer of 2002, according to a recent study by scientists at the University of Colorado. This continues a trend of successive record minima in the 1990s. At the same time, the amount of melt water flowing from the Greenland Ice Sheet into the surrounding seas in 2002 broke all known melt records for the island. These events further concerns that climate change is significantly altering the Arctic.
