ItÃ¢â‚¬â„¢s becoming a recurring theme. Climate change has again been identified as a major threat by global businesses, according to a new survey on emerging risks conducted by Business Continuity Expo 2008 and sponsored by Marsh. Its findings reveal that some 87 percent of businesses see climate change as the single biggest threat in terms of risk assessment and the effect it could have on their businesses future growth. Perhaps of more concern, many are at a loss as to what can be done in order to prepare or plan for this eventuality. To embellish the point, the threat posed by climate change to the continuity and long-term success of their business is ahead of terrorism, pandemic flu, flooding, the credit crunch, government red-tape and outsourcing and offshoring. The survey was conducted among 150 major U.K. and European companies.
