Alister Doyle has worked as Reuters Environment Correspondent since 2004, mainly covering U.N. negotiations including the Copenhagen summit in 2009 and the science of climate change. A British citizen based in Oslo, the job has taken him to places ranging from the Arctic to Antarctica, where he was on the last flight to land on a part of the Wilkins Ice shelf before it collapsed in early 2009. Previously, he had postings with Reuters in Paris, Central America, Brussels and London in a career stretching back to 1982. He is a graduate of Oxford University where he studied French and Spanish.
