Global warming is evaporating Arctic ponds, new study shows

07-02-2007 · EurekAlert!

High Arctic ponds -- the most common source of surface water in many polar regions -- are now beginning to evaporate due to recent climate warming, say two of Canada's leading environmental scientists.

  1. Rising CO2 signals wetter storms for Northern Hemisphere, says CU-Boulder study
    12-11-2007 · EurekAlert!
    While two new studies by researchers at the University of Colorado at Boulder's Cooperative Institute for Research in Environmental Sciences predict wetter storms for the Arctic and for the Northern Hemisphere because of global warming, whether or not this means more net precipitation depends on the latitude.

  2. Shrinking ponds signal warmer, dryer Alaska
    10-12-2006 · EurekAlert!
    A first-of-its kind analysis of 50 years of remotely sensed imagery from the 1950s to 2002 shows a dramatic reduction in the size and number of more than 10,000 ponds in Alaska. The analysis, by University of Alaska Fairbanks scientists and published this week in the Journal of Geophysical Research, indicates that these landscape-level changes in arctic ponds are associated with recent climate warming in Alaska and may have profound effects on climate and wildlife.

  4. Despite polarized opinions, Democrats and Republicans perform same amount of 'green' actions
    01-31-2008 · EurekAlert!
    Political party affiliation has little bearing on the number of "green" actions people take, a new study by Porter Novelli and George Mason University shows. According to the survey of more than 11,000 American adults and nearly 1,000 of their children, Democrats on average perform only about 15 percent more "green" actions than Republicans, despite great differences in the two parties' perceptions of danger related to global warming.

  5. 1,000-year-old Arctic ponds disappearing due to global warming
    07-02-2007 · EurekAlert!
    Research has uncovered alarming evidence that high Arctic ponds, many have been permanent bodies of water for thousands of years, are completely drying out during the polar summer. These shallow ponds are important indicators of environment change and are especially susceptible to the effects of climate change because of their low water volume.Researchers studied these Arctic ponds over 24 years. This data represents the longest record of systematic limnological monitoring from the high Arctic.

    When Elizabeth Thomas, a graduate student at the University at Buffalo, travels this month to Baffin Island in the northeast Canadian Arctic, she not only will be sampling sediments from the bottom of frozen lakes, she also will be educating a native Inuit class about global warming, taking local schoolchildren on a sediment-coring field trip and may participate in a call-in radio show with translators that will be broadcast in Inuktitut, the local language.

  7. Early fire risk for mountains near Los Angeles
    07-01-2007 · EurekAlert!
    Researchers at the University of Utah and elsewhere developed a new way to predict when vegetation dries to the point it is most vulnerable to large fires in the Santa Monica Mountains near Los Angeles. This year's forecast says the highest-risk fire period will begin July 13 -- weeks earlier than usual. Yet the study also shows that global warming hasn't caused any apparent long-term trend toward early fire seasons in the Santa Monicas.

    09-05-2007 · EurekAlert!
    Global warming may be to blame for the gradual extinction of cold-loving species, and the European land leech in particular, according to a study which will be published in the December issue of Springer’s journal Naturwissenschaften. The findings show that human-induced temperature increases over a 40-year period in the Graz region of Austria may have led to the near extinction of the local land leech Xerobdella lecomtei.

    Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online today in Science. The study was carried out by an international team led by researchers at the Katholieke Universiteit Leuven, Belgium, the University of Exeter, UK, and the University of California, Davis.

  10. Carbon sink capacity in northern forests reduced by global warming
    01-02-2008 · EurekAlert!
    An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period has on average decreased due to warmer autumn temperatures. Many northern terrestrial ecosystems currently lose carbon dioxide in response to autumn warming, offsetting 90 percent of the increased carbon dioxide uptake during spring.
