Latest Arctic shrinkage Stories
The pending federal decision about whether to protect the polar bear as a threatened species is as much about climate science as it is about climate change.
A new NASA-led study found a 23-percent loss in the extent of the Arctic's thick, year-round sea ice cover during the past two winters. This drastic reduction of perennial winter sea ice is the primary cause of this summer's fastest-ever sea ice retreat.
There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported.
Arctic sea ice is melting three times faster than many scientists project, U.S. researchers reported Monday, just days ahead of the next major international report on climate change.
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.
By David Fogarty MONTREAL (Reuters) - The chief scientist aboard the Canadian icebreaker CCGS Amundsen knows all about climate change.
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.
Sinking villages perched on thawing permafrost, an explosion of timber-chewing insect populations, record wildfires and shrinking sea ice are among the most obvious and jarring signs that Alaska is getting warmer as the global climate changes, scientists say. Atmospheric temperatures in the remote state have risen 3.6 to 5.4 degrees Fahrenheit over the past five decades.
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.
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 Geophysical...
