Debating global warming: New climate data
From Pittsburghlive.com, November 29, 2008
Royal Navy logbooks dating to the 17th century might chart a new course from vague assumptions to verifiable reason in the stormy debate over global warming.
Mariners’ well-kept records detailing air pressure, wind speed and air and sea temperatures provide a snapshot of previous climate conditions. For a group of British academics and scientists examining historic climate changes, it’s a “treasure trove” of information, they say.
In a preliminary study of 6,000 logbooks, questions already are being raised that challenge the conclusions of global warming’s Chicken Littles. For instance, Europe in the 1730s experienced a period of rapid warming — not unlike that of recent years — which clearly wasn’t attributable to man-made influences.
In 2005, scientists linked Hurricane Vince, which developed in an area of low sea-surface temperatures, to climate change. Yet the old logbooks detail a similar hurricane in 1842 that followed the same trajectory. Mere coincidence?
What’s revealed is the complexity of climate science, says Dr. Dennis Wheeler, a University of Sunderland scientist, “and that it’s wrong to take particular events and link them to CO2 emissions.”
Are the ship logs conclusive? Perhaps no more so than the claims of global warming alarmists. But it’s data that should be carefully researched. Something we can’t say of the data deceptively manipulated to argue that the debate has ended regarding man’s role in planetary climate change.
