Rather than try to predict which dams were most likely to fail, the study's authors looked at which lakes would pose the most danger if they burst out.They also stress the importance of early warning systems such as time-lapse cameras."It's an important paper," said Stephan Harrison, a leading expert on the impact of climate change on glacial lakes at the University of Exeter, who was not involved in the research. "It alerts policymakers to the likely impact of future climate change."
