U.S.-led scientists conducting an ecosystem study of arctic warming say they've determined the arctic, as we know it, might soon be a thing of the past. The international team, led by Penn State University Associate Professor Eric Post, carried out studies of the biological response to arctic warming during the fourth International Polar Year that ended in 2008 and documented a wide range of responses by plants, birds, animals, insects and humans living in the region. Post said his team...

A new study indicates that Arctic temperatures suddenly increased during the last 50 years of the period from 1 AD to the year 2000. Because this warming occurred abruptly during the 20th Century while atmospheric greenhouse gases were accumulating, these findings provide additional evidence that humans are influencing climate. Incorporating geologic records, biologic records and computer simulations, the study reconstructed Arctic summer temperatures at a resolution down to decades, and...

Arctic thawing is likely to result in worldwide consequences - from an increase in greenhouse gases and global weather pattern changes, according to a WWF report on Wednesday. The World Wildlife Fund released a new study, titled "Arctic Climate Feedbacks: Global Implications," Wednesday that found that Arctic ice is shrinking at a much quicker pace than previously expected. The thawing Arctic is likely to have far-reaching implications that will affect hundreds of millions of people, WWF...

Average ocean surface temperatures reached an all-time high in July, according to a new US agency report. The National Oceanic and Atmospheric Administration's National Climatic Data Center reported Thursday that the average global ocean temperature reached 62.6 degrees in July "“ replacing the previous high temperature record set in 1998. The combined average of global land and surface temperature during July ranked fifth in the overall warmest since records began in 1880, according to...

The National Science Foundation (NSF) made its first major award under the American Recovery and Reinvestment Act to construct the Alaska Region Research Vessel (ARRV). This investment will not only provide a technologically advanced tool for science but help preserve jobs and promote economic recovery. The three-year construction phase of the project will support 4,350 total jobs--750 directly at the shipyard and as many as 3,600 in the broader economy. NSF intends to ensure that the ARRV is...

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...

Autonomous vehicle developed by the University of Washington is an element of Arctic Observing Network, an International Polar Year research priority An intelligent, ocean-going glider has spent six months on a record-breaking deployment to sample the icy waters off western Greenland. The samples will contribute to the longest continuous measurement of Arctic currents that help to drive ocean circulation and regulate global seawater temperatures. The 49-kilogram (110-pound) seaglider,...

WASHINGTON, April 6 /PRNewswire-USNewswire/ -- The latest Arctic sea ice data from NASA and the National Snow and Ice Data Center show that the decade-long trend of shrinking sea ice cover is continuing. New evidence from satellite observations also shows that the ice cap is thinning as well. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) Arctic sea ice works like an air conditioner for the global climate system. Ice naturally cools air and water masses, plays a key role in...

According to new analysis, arctic sea ice is melting so fast that the majority of it could be gone within the next 30 years.  The forecast is based on analysis generated using computer models of weather and climate.If the white ice melts, it will be replaced with dark ocean surface that will absorb sunlight. This will then speed up the global warming process.The findings increase concern about global warming, a problem that has become a focus of the G20 discussions under way in...

Arctic reindeer herders are facing the challenges of adapting to climate change as a warmer Arctic climate makes it harder for herds to find food and navigate. To help them adapt, the ESA-backed Polar View initiative is providing the herders with satellite-based snow maps. "Snow is of paramount importance for reindeer herding because its quality determines whether reindeer are able to access the pastures that lie beneath it for much of the year," said Anders Oskal, the Director of the...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
