It's hard to make data where none exist

Unless of course, you are trying to convince the world that Antarctica is warming.

Washington, DC: A new study on Antarctic temperatures – which is contrary to the findings of multiple previous studies - claims "that since 1957, the annual temperature for the entire continent of Antarctica has warmed by about 1 degree Fahrenheit, but still is 50 degrees below zero.

Despite the fact that the study was immediately viewed with major skepticism by scientists who are not skeptical of anthropogenic global warming claims, many in the media pounced on the study as a chance to attack those skeptical of man-made climate doom. According to the release of the study, “The researchers devised a statistical technique that uses data from satellites and from Antarctic weather stations to make a new estimate of temperature trends. […]

The scientists found temperature measurements from weather stations corresponded closely with satellite data for overlapping time periods. That allowed them to use the satellite data as a guide to deduce temperatures in areas of the continent without weather stations.” (emphasis added)

Few media outlets noted that in 2007 Antarctic “sea ice coverage has grown to record levels since satellite monitoring began in the 1979, according to peer-reviewed studies and scientists who study the area.” [See also other factors impacting Antarctica: “Volcano, Not Global Warming Effects, May be Melting an Antarctic Glacier & The Antarctic deep sea gets COLDER – April 21, 2008 & A January 12, 2008, peer-reviewed paper in AGU (American Geophysical Union) found “A doubling in snow accumulation in the western Antarctic Peninsula since 1850.Map of Volcanoes - See comprehensive data round up below]

The new Antarctic study was published in Thursday's issue of the journal Nature and the lead author of the study was Eric Steig, a University of Washington professor of Earth and Space Sciences. Other co-authors include: David Schneider of the National Center for Atmospheric Research in Boulder, Colorado, a former student of Steig's; Scott Rutherford of Roger Williams University in Bristol, RI; and Michael Mann of Pennsylvania State University.

UN IPCC lead author, Dr. Kevin Trenberth, who is not in any way a climate change skeptic, said of the study, "I remain somewhat skeptical… It is hard to make data where none exist.” Echoing Trenberth’s analysis were several other scientists.
