The likelihood of summer Arctic ice cover disappearing within the next few years is unlikely, according to researchers from the University of Colorado at Boulder, though the minimum of ice found in the ocean has dipped to its third lowest levels since 1979. According to a press release, scientists at the university's National Snow and Ice Data Center (NSIDC) found that the Arctic ice extent dropped to 1.84 million square miles at its lowest point, on September 10. That is 630,000 square miles...

GREENBELT, Md., Sept. 1 /PRNewswire-USNewswire/ -- Operation IceBridge - a NASA airborne mission to observe changes in Earth's rapidly changing polar land ice and sea ice - is soon to embark on its fourth field season in October. The mission is now paralleled by a campaign to bring data to researchers as quickly as possible and to accelerate the analysis of those changes and how they may affect people and climate systems.

A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year. The new study, which looked at temperatures during the early Eocene period 52 to 53 million years ago, also has implications for the impacts of future climate change as Arctic temperatures continue...

NASA's first dedicated oceanographic field campaign goes to sea next week to take an up-close look at how changing conditions in the Arctic are affecting the ocean's chemistry and ecosystems that play a critical role in global climate change. The ICESCAPE mission, which stands for "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," will investigate the impacts of climate change on the ecology and biogeochemistry of the Chukchi and Beaufort seas along Alaska's...

NASA will hold a media teleconference at 1 p.m. EDT on Tuesday, June 8 to preview the agency's first dedicated oceanographic research voyage. During the mission, scientists will study changing Arctic climate and ice conditions affecting ocean ecosystems. The "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment" mission, or ICESCAPE, will investigate how climate change in the Arctic may be altering the ocean's ability to absorb carbon from the atmosphere. The...

The U.S. National Snow and Ice Data Center reports that the extent of sea ice over the Arctic Ocean grew until the last day of March, which is the latest the annual melting season has begun in 31 years of satellite records. The center said in a statement on Wednesday that cold weather and winds from the north over the Bering Sea and Barents Sea meant the area of ocean covered by ice expanded through last month.  That is two days later than in 1999, the previous latest start to a melting...

Australian and US scientists have discovered how changes in winds blowing on the Southern Ocean drive variations in the depth of the surface layer of sea water responsible for regulating exchanges of heat and carbon dioxide between the ocean and the atmosphere. The researchers' findings "“ published on-line today in Nature Geoscience "“ provide new insights into natural processes which have a major influence on the rate of climate change. The surface-mixed layer is a crucial...

A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages may have been higher than previously thought A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. The findings, reported this week by...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
