Studies that link a spike in hurricane intensity with global warming are spotting "artificial upward trends" because they rely on bad historical data, a paper suggested today in the journal Science.Just some food for thought.Hurricane intensity is measured by the storms' surface winds. Sometimes those winds are estimated by looking at satellite pictures, using a subjective technique invented in 1972.
Better technology since then, including greater satellite coverage, has led inevitably to higher wind-speed estimates for more recent storms, the authors suggest.
