NASA will hold a media teleconference at 11:30 a.m. EDT on Thursday, Oct. 8, to preview the agency's largest airborne research effort ever to study Antarctic ice sheets, ice shelves and sea ice. The flights are part of NASA's Operation Ice Bridge, a six-year airborne campaign to each of Earth's polar regions that will extend and expand NASA's multi-year record of space-based observations of ice conditions. Advancing scientific understanding of the behavior of polar ice is needed to improve...

Scientists are taking a more in-depth view of how climate change could affect Antarctica's ice, and how even a small change in temperature could lead to a global rise in sea levels. "If you're going to have even a few meters it will change the geography of the planet," Rajendra Pachauri, head of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) told Reuters. "Greenland and Antarctica are two huge bodies of ice sitting on land that could really have very serious implications for the...

New, three-dimensional imaging of Martian north-polar ice layers by a radar instrument on NASA's Mars Reconnaissance Orbiter is consistent with theoretical models of Martian climate swings during the past few million years. Alignment of the layering patterns with the modeled climate cycles provides insight about how the layers accumulated. These ice-rich, layered deposits cover an area one-third larger than Texas and form a stack up to 2 kilometers (1.2 miles) thick atop a basal deposit with...

This summer's melt of Arctic sea ice might not have been quite as bad as the past two years, but satellite images reveal that it has now had the third biggest melt in 30 years, according to U.S. government scientists. The announcement was made on Thursday by the National Snow and Ice Data Center, which reported that the Arctic sea ice pack had reached its yearly minimum just last Saturday. It will not begin to grow again until fall begins. As of last Saturday, the sea ice only covered...

Researchers have confirmed for the first time a link between declining levels of atmospheric carbon dioxide (CO2) and the formation of Antarctic ice caps some 34 million years ago. The results of the major research study support computer climate models that predict both the creation of ice sheets when CO2 levels fall and the melting of ice caps when CO2 levels rise. "Our study is the first to provide a direct link between the establishment of an ice sheet on Antarctica and atmospheric carbon...

Scientists continue to keep a close eye on the Arctic Ocean, which has given up tens of thousands of square miles of ice this summer. Eddie Gruben, a local observer in far northwest Canada, told the Associated Press he has watched the summer ice retreat for years. By this weekend the ice edge lay 80 miles at sea. "Forty years ago, it was 40 miles (64 kilometers) out," added Gruben, 89. According to researchers, the global average temperature rose 1 degree Fahrenheit over the past century, but...

WASHINGTON, July 7 /PRNewswire-USNewswire/ -- Arctic sea ice thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record. The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover.

The new results, based on data from a NASA Earth-orbiting spacecraft, provide further evidence for the rapid, ongoing transformation of the Arctic's ice cover. Scientists from NASA and the University of Washington in Seattle conducted the most comprehensive survey to date using observations from NASA's Ice, Cloud and land...

A professor from the University of Cambridge believes that the once-permanent ice found in the Arctic may now be so thin that it could be eliminated during the summer seasons in about a decade. Professor Peter Wadhams told BBC News that ice in the Arctic is headed toward being only visible during the winter. "By 2013 we will see a much smaller area in summertime than now, and certainly by about 2020, I can imagine that only one area will remain in summer." Scientists have previously projected...

Former Vice President Al Gore called for fast action to avert the potentially irreversible melting of the Earth's ice. Speaking at the first conference to exclusive discuss the planet's melting ice, the Nobel prize winning climate champion warned that the situation is worse than previous worst-case scenarios projected by experts just a few years ago. The Tromsoe, Norway, conference comes just months ahead of a U.N. climate summit set for December in Copenhagen. "This conference is a global...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
