Report: Global Sea Ice at 'Unprecedented' Levels
Donât expect to hear this reported on the your evening newscast, but according to new data, sea ice levels in the Southern Hemisphere are at 25-year highs.
âOn a global basis, world sea ice in April 2008 reached levels that were âunprecedentedâ for the month of April in over 25 years,â Steve McIntyre wrote on Climateaudit.org on May 4. âLevels are the third highest (for April) since the commencement of records in 1979, exceeded only by levels in 1979 and 1982.â
McIntyre, along with Ross McKitrick, debunked the validity of the âhockey stickâ graph used in a journal article by Michael Mann, which described the increase in Northern Hemisphere mean temperature. The two claimed Mannâs graph was based on flawed calculations and data defects.
That data from the National Oceanic and Atmospheric Administrationâs (NOAA) National Snow and Ice Data Center (NSIDC) suggests the effects of global warming arenât as dire as some media reports would have you believe. A segment on ABCâs March 28 âGood Morning Americaâ warned melting sea ice is endangering the global warming alarmistsâ favorite mascot, the polar bear.
â[I] realize what I need to do is try and tell these stories through National Geographic magazine by using animals such as polar bears to hang this campaign on, to say that if we lose sea ice in the Arctic, and projections are to lose sea ice in the next 20 to 50 years, we ultimately are going to lose polar bears as well,â National Geographic magazine photographer Paul Milkin said to ABCâs Sam Champion.
âGetting manhandled may ruffle their feathers, but it was key to discovering their fate,â â60 Minutesâ contributor Scott Pelley said. âThese are grown penguin chicks chasing their mothers for food, which she delivers beak to beak. Soon, the chicks will go to sea to hunt for a shrimp-like crustacean called krill. The krill grow beneath the sea ice, but in the warming ocean, the sea ice is melting away.â
âSo the penguins have been going to sea and starving to death?â Pelley asked Sue Trivelpiece of NOAAâs Antarctic Ecosystem Research Division.
âThe chicks are declining and we think they just canât find the krill,â Trivelpiece replied.
Although sea ice has actually increased, it isnât clear if the penguinsâ food supply will increase and the species native to the polar regions of the Southern Hemisphere will once again thrive.
