Though British Columbia’s hydrologists have fifty years of stream flow data to formulate its’ responses to climate change, a recent study from the University of Victoria shows this is not enough. Tree ring data shows that, since 1658 AD, there have been 16 droughts exceeding anything evidenced in the instrumental record. The most recent and severest of  these events took place in 1958. According to one of the study co-authors, Bethany Coulthard, “It was a cool time and yet we still saw these extreme natural droughts.” Add problems like urbanization, deforestation and rising Global temperatures into the equation and we can expect a mega-sized drought coming to BC.
