A paper led by Corey Lesk, who was an undergraduate research assistant for Navin during his McGill days, has just been published in Nature. Using reported extreme weather disasters from 1964-2007, the authors examined the effects these events have had on crop production at the global scale. Amongst their findings, they show the negative impact that drought and extreme heat events have had on agricultural production in the recent past, and that these events have a greater impact in developed countries. The paper is already receiving a lot of coverage in the press (McGill,UBC,New York Times). Congratulations Corey, Pedram, and Navin!
