Dedicated to the balanced discussion of global warming
LiveScience – May 15, 2007
This is a news report about recent melting of ice in Antarctica. The article does not make claims of the cause of the warming that melted this ice but does discuss the potential ramifications of the ice melt.
Warm temperatures melted an area of western Antarctica that adds up to the size of California in January 2005, scientists report.
Satellite data collected by the scientists between July 1999 and July 2005 showed clear signs that melting had occurred in multiple distinct regions, including far inland and at high latitudes and elevations, where melt had been considered unlikely.
Changes in the ice mass of Antarctica, Earth’s largest freshwater reservoir, are important to understanding global sea level rise. Large amounts of Antarctic freshwater flowing into the ocean also could affect ocean salinity, currents and global climate.
Maximum high temperatures of 41 degrees Fahrenheit that persisted for about a week in Antarctica caused a melt intense enough to create an extensive ice layer.
No further melting has been detected through March 2007.
