Breitbart.com Alleges Australia “Criminally” Doctored Data to Show Warming Trend
Climate change denial is becoming more and more difficult as scientific evidence mounts and public opinion agrees, however that does not mean that they have given up the fight. In a report from Breitbart.com (the London edition, apparently), they claim that the Australian Bureau of Meteorology “criminally adjusted” data on global warming.
The argument centers around the practice of homogenization of climate data in order to give a more accurate depiction of large-area temperatures. For example, a thermometer in the center of New York City would most likely register higher temperatures than one at La Guardia airport or surrounding, more rural areas (known as the “Heat Island Effect”). However those temperatures are homogenized so that a single temperature can be reported for the entire area.
This is what the Australian BOM did that so ruffled the feathers of climate change deniers, making them refer to a common scientific practice as criminal. “At Ruthergelen, Victoria, a cooling trend of -0.35 degrees C per century,” Breitbart.com reports, “was magically transformed at the stroke of an Australian meteorologist’s pen into a warming trend of 1.73 degrees C per century.”
Of course, there was nothing magical about it as it is, again, a commonly-used scientific technique. Yet scientist Jennifer Marohasy – who self-describes as “a libertarian who holds unpopular opinions on a range of important environmental issues” – finds the homogenization suspicious. As we’ve pointed out in the past, some scientists stake their careers are challenging scientifically-accepted opinion either to “make waves” or simply force them to reaffirm their findings.
In a report from The Australian, David Karoly, a professor at Melbourne University, referred to these criticisms as coming from “amateurs.” He suggested that rather than “constitute a debate,” Marohasy should submit her claims “for publication in scientific journals and [have them] peer-reviewed by experts, to assess the validity” of her argument.
