September 20, 2007: NASA Researchers Find Snowmelt in Antarctica Creeping Inland. “…Only satellites can fully capture the extent of changes in snow melting…researchers [including Tedesco] …confirmed that Antarctic snow is melting farther inland…melting at higher altitudes than ever, and increasingly melting on Antarctica’s largest ice shelf.” How on earth does this square with the obvious decrease in melt just published by the same researchers? Doesn’t this press release demand another on the newer work?
Earth to NASA: The 2007 Antarctic paper used twenty years of data, the 2009 paper has the entire record back to 1980. Even looking at the graph through 1998, it’s apparent that there is no net increase in melt.
September 25, 2007: NASA finds Greenland Snow Melting Hit Record High in High Places. This one is unbelievably misleading. “In fact, the amount of snow that has melted this year over Greenland is the equivalent of more than twice the surface size of the U.S.”. This is patently impossible – as Greenland’s total area is about a quarter of that of the lower 48 states.
There’s more. In the most recent paper, Tedesco and his co-authors take pains not to step on a highly publicized study of surface temperature trends published by University of Washington’s Eric Steig that was hailed as evidence for human-induced warming. At the time it was published, critics pointed out that there was no trend whatsoever in recent decades and that what warming had occurred took place before the great increase in atmospheric carbon dioxide.
Indeed, Tedesco begins his conclusions by stating that his results “do not contradict” the Steig study. Why? According to Tedesco, because Steig’s work begins in the 1950s, long before his 1980 start date. All this did was to confirm that warming pretty much stopped three decades ago. Where’s that press release?
NASA’s seems to beat the drum only when the news on global warming is bad, and remains mute when it is good. And, for that matter, so is that of the environmental journalism community, apparently incapable of filing an original story about an article from a refereed scientific journal that flies in the face of previous reportage on climate change.
