If the Earth has a fever, as former Vice President Al Gore suggests, it's not showing signs of it.
According to Climateaudit.org's Steve McIntyre, global sea ice has actually increased.
"On a global basis, world sea ice in April 2008 reached levels that were ‘unprecedented' for the month of April in over 25 years," Steve McIntyre wrote on Climateaudit.org on May 4. "Levels are the third highest (for April) since the commencement of records in 1979, exceeded only by levels in 1979 and 1982."
That data from the National Oceanic and Atmospheric Administration's (NOAA) National Snow and Ice Data Center (NSIDC) suggests the effects of global warming aren't as dire as some media reports would have you believe. A segment on ABC's March 28 "Good Morning America" warned melting sea ice is endangering the global warming alarmists' favorite mascot, the polar bear.
"[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," National Geographic magazine photographer Paul Milkin said to ABC's Sam Champion.
According to the NSIDC data, sea ice had declined in 2007 to record lows, but showed a rebound in 2008, particularly in the Southern Hemisphere.
McIntyre, along with Ross McKitrick, debunked the validity of the "hockey stick" graph used in a journal article by Michael Mann, which described the increase in Northern Hemisphere mean temperature. The two claimed Mann's graph was based on flawed calculations and data defects.
