(Bloomberg) -- Climate change and large-scale forced migration are the greatest risks facing the world according to a survey by the World Economic Forum, the organizer of next week’s meeting in Davos.

The 2016 report, published Thursday, highlighted the most significant threats expected over the next decade, based on a survey of more than 750 experts. Not dealing with climate change is seen as the risk with the greatest potential impact, ahead of weapons of mass destruction and water crises in second and third place. Migration tops the list in terms of likelihood.

“Climate change is exacerbating more risks than ever before in terms of water crises, food shortages, constrained economic growth, weaker societal cohesion and increased security risks,” Cecilia Reyes, chief risk officer at Zurich Insurance Group AG, said in a statement. “Meanwhile, geopolitical instability is exposing businesses to canceled projects, revoked licenses, interrupted production, damaged assets and restricted movement of funds across borders. These political conflicts are in turn making the challenge of climate change all the more insurmountable.”
