Latest Climate of the Arctic Stories

In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations. Daily satellite observations have shown snow melting on Greenland's ice sheet over an increased number of days. The resulting data help scientists understand better the speed of glacier flow, how much water will pour from the ice sheet into the surrounding ocean and how much of the sun's radiation will...

A new study by NASA scientists suggests that greenhouse-gas warming may raise average summer temperatures in the eastern United States nearly 10 degrees Fahrenheit by the 2080s. "There is the potential for extremely hot summertime temperatures in the future, especially during summers with less-than-average frequent rainfall," said lead author Barry Lynn of NASA's Goddard Institute for Space Studies and Columbia University, New York. The research found that eastern U.S. summer daily high...

A new NASA study has found that in 2005 the Arctic replaced very little of the thick sea ice it normally loses and replenishes each year. Replenishment of this thick, perennial sea ice each year is essential to the maintenance and stability of the Arctic summer ice cover. The findings complement a NASA study released in fall 2006 that found a 14-percent drop in this perennial ice between 2004 and 2005. The lack of replenishment suggests that the decline may continue in the near future....

WASHINGTON -- It's becoming harder to find the right snow to build an igloo, and melting permafrost is turning land into mud. With climate change the nature of the Arctic is changing, too, in ways that worry the people who live there. The Smithsonian's National Museum of Natural History opens a pair of exhibits on Saturday: "Arctic: A Friend Acting Strangely," and "Atmosphere: Change is in the Air," discussing what is happening to the climate and how it affects people living in the planet's...

Arizona -- The Earth's warming temperatures are on track to melt the Greenland and Antarctic ice sheets sooner than previously thought and ultimately lead to a global sea level rise of at least 20 feet, according to new research. If the current warming trends continue, by 2100 the Earth will likely be at least 4 degrees Fahrenheit warmer than present, with the Arctic at least as warm as it was nearly 130,000 years ago. At that time, significant portions of the Greenland and Antarctic Ice...

NASA -- If you live somewhere in the northern hemisphere between Jacksonville, Florida and Juneau, Alaska or in the southern hemisphere between Porto Alegre in Southern Brazil and Tierra del Fuego, in southern Argentina, you may have noticed that since 1965, there are less rainy and snowy days. You may have also noticed that when storms do come by they bring more rain or snow than they used to in the past. Both of those observations have been proven to be true. What you may not know, though,...

By David Fogarty MONTREAL -- On the surface, polar bears and coral atolls don't have much in common but when it comes to global warming they have plenty to link them. Rising seas and more frequent and severe storms are threatening the livelihoods of indigenous groups in the Arctic and small tropical island states, forcing some communities to relocate while driving up business costs and threatening tourism. "These are the two most vulnerable regions to climate change," said Sheila...

By Timothy Gardner NEW YORK (Reuters) - The Arctic ice shelf has melted for the fourth straight year to its smallest area in a century, driven by rising temperatures that appear linked to a buildup of greenhouse gases, U.S. scientists said on Wednesday. Scientists at NASA and the National Snow and Ice Data Center, which have monitored the ice via satellites since 1978, say the total Arctic ice in 2005 will cover the smallest area since they started measuring. It is the least amount...

New satellite records monitored by a national team of collaborators show a four-year pattern of extremely low summer sea-ice coverage in the Arctic that continued in September 2005, which may be the result of warming temperatures and earlier spring melting. Since 2002, the satellite data have revealed unusually early springtime melting in areas north of Siberia and Alaska. In 2005, the trend expanded to include the entire Arctic ice pack, said Ted Scambos of CU-Boulder's National Snow and...

WASHINGTON -- Warming in the Arctic is stimulating the growth of vegetation and could affect the delicate energy balance there, causing an additional climate warming of several degrees over the next few decades. A new study indicates that as the number of dark-colored shrubs in the otherwise stark Arctic tundra rises, the amount of solar energy absorbed could increase winter heating by up to 70 percent. The research will be published 7 September in the first issue of the Journal of...
