Explaining extreme events of 2013 from a climate perspective
A report investigates the causes of a wide variety of extreme weather and climate events from around the world in 2013. Published by the Bulletin of the American Meteorological Society, "Explaining Extreme Events of 2013 from a Climate Perspective" addresses the causes of 16 individual extreme events that occurred on four continents in 2013. Of the five heat waves studied in the report, human-caused climate change-primarily through the burning of fossil fuels-was found to have clearly increased the severity and likelihood of those events. On the other hand, for other events examined like droughts, heavy rain events, and storms, fingerprinting the influence of human activity was more challenging. The influence of human-caused climate change on these kinds of events was sometimes evident, but often less clear, suggesting natural factors played a far more dominant role.
