Happening This Week

Climate change once again tops the list of the World Economic Forum's Global Risks 2015. The looming water crisis ranks first in impacts, and extreme weather events comes #2 in likelihood. "Failure of climate adaptation" comes out as #5 in terms of impacts, and #7 in likelihood - of greater impact than unemployment, the fiscal crisis or cyber-attacks.
Climate change impacts cut across many risk categories - the spread of infectious diseases (#2 impact), interstate conflicts (#1 likelihood), together with many other potential social and governance disruptions, can be exacerbated by climate change.
As climate change reshuffles the cards, it is crucial to know where your business might be exposed to extreme weather events, water stress or failing infrastructure. Contact us for a complimentary 30-minute consultation: climate@427mt.com or 415.930.9090.
