Migratory species face disaster from the effects of climate change unless urgent action is taken, according to the preliminary findings of a forthcoming United Nations-backed report. “Increasing temperatures, changes in precipitation, sea level rise, ocean acidification, changes in ocean currents and extreme weather events will all affect migratory species populations,” said Aylin McNamara, who led the research project at the Zoological Society of London. “It's hard to see how any of these species will be able to survive” under the current “business as usual” approach to controlling greenhouse emissions, she said today. “I'm afraid that's how serious the situation is.” International efforts for species conservation across national borders and to mitigate climate change were imperative, Ms. McNamara added. “These vulnerability assessments show us the likely order in which these species will become extinct” if such action is not taken.
