Happening This Week

The City of San Francisco is taking a pioneering step towards climate change adaptation by incorporating sea level rise and flood risk into development decisions. This new policy comes just a week before the two year anniversary of the devastation from Hurricane Sandy, largely caused by storm surges predicted to be more prevalent with increased sea level rise. Prospective projects in areas at flood risk may not receive funding, or may have to include hazard-reduction measures before getting approval. Although limited to public projects, $25 billion worth of development decisions over the next decade will now include sea level rise considerations. The coast of California is home to $100 billion of risk from climate change-induced sea level rise, with the Bay Area being one of the most vulnerable hot spots.

While the private sector is not currently subject to the same oversight, forward-looking corporations are quickly coming to the realization of the economic necessity of preparing for climate change. Including a focus on business continuity through the lens of climate change risks increases a company's chance of not only surviving historic-level storms such as Katrina and Sandy, but is also correlated with being more competitive on a day-to-day basis.
