A Strong Rebuke for Paper
That Forecasted `Climate Departure’
Thirteen climate scientists and meteorologists have published a sharp criticism
of a paper
by University of Hawaii biogeographer Camilo Mora, who calculated dates when earth’s climate will move into a new state caused by human-driven global warming. Mora and his ideas were featured in an interview
last week at Yale Environment 360
. In a comment article in Nature
, the 13 scientists say that Mora and his colleagues used faulty methodology that produced artificially early dates when specific regions would reach “climate departure.” They also said Mora underestimated the uncertainty involved in forecasting the time of emergence of a new climate regime. “This overconfidence could impair the effectiveness of climate risk management decisions,” the 13 scientists said in their comment. In his own comment
, Mora defended his methods and said that “our findings are conservative and remain unaltered in the light of their analysis.” Nature
commissioned an independent climate scientist — Scott B. Power of Australia’s Bureau of Meteorology — to assess the arguments
of the two sides. Power said that while the 13 scientists presented a more appropriate estimate of when the planet could enter a new climatic state, “important conclusions of Mora and co-workers’ original paper remain valid.”
