这意味着改变自己：重新设计我们的港口，管理我们的海岸线，以及建设我们的建筑和交通系统从而限制更加频繁和更具威力的飓风所造成的损害。罗森兹威格是美国国家航空航天局戈达德空间研究中心（NASA Goddard Institute for Space Studies）资深研究科学家，同时也是一个名为“纽约市应对气候变化专门委员会”（New York City Panel on Climate Change）的咨询委员会的联席主席。他说像雨水沟这么简单的东西经设计后就可以用来将地铁、铁路和污水处理厂的淹水最小化。9.11之后，高盛集团（Goldman Sachs）在设计其位于曼哈顿下城的新总部时，安装了一套强大的发电机，尽管它所处的楼层非常高，足以避开最近发生的洪水灾害。众所周知，荷兰人正面临海平面上升的威胁，他们现在设计的公寓大厦可以抵御大量的水流进出建筑的情况。
除了重新考虑建设方式之外，我们还应该重新考虑在哪里建设。联邦洪水保险（Federal flood insurance）补贴那些在飓风袭击后重建家园的屋主和企业主，这已经耗费了美国纳税人数十亿美元。如果取消联邦洪水保险，私营市场在制定保险价格时将更加现实（因此也会更高），容易遭受袭击的海岸线地区可能会因此遭遇发展方面的制约。
It took a disaster on the scale of Hurricane Sandy to finally get some high-profile politicians talking about the impact of climate change. In the wake of a heavy death toll and an estimated $50 billion in damage from the storm surge, New York Governor Andrew Cuomo argued that the state must consider building a series of seawalls around New York City -- at a cost of at least $10 billion. In a recent editorial, Mayor Michael Bloomberg echoed what many climate scientists and experts have been saying for some time now: It's too late to reverse the negative consequences of global warming; the best we can do, as one leading hedge fund manager told me, is "get used to it."
This means adaptation: redesign our ports, manage our coastlines, and construct our buildings and transportation systems to limit the damage caused by more frequent and more powerful storms. Cynthia Rosenzweig, a senior research scientist at NASA Goddard Institute for Space Studies who co-chairs an advisory board called the New York City Panel on Climate Change, says that something as simple as a storm drain could be engineered to minimize subway, rail, and sewage-treatment-plant flooding. After 9/11, Goldman Sachs (GS) designed its new headquarters in lower Manhattan with a set of powerful electrical generators on a floor high enough to be safe from the recent floodwaters. The Dutch, who know about living close to rising seas, are designing apartment towers that allow for massive water flow into, and out of, the structures.
Besides rethinking how we build, we have to rethink where we build. Federal flood insurancesubsidizes home and business owners who rebuild after a storm, and that has cost U.S. taxpayers billions. By eliminating federal flood insurance, the private market will price policies more realistically (and thus higher), which would limit development along vulnerable coasts.
The most extreme remedy would be to construct sea gates to ward off storm surges. Many cities around the world, including London, Singapore, and Rotterdam, have such gates. New York City may well need to build its own, but they present many problems besides their high cost. For example, engineers usually design a structure to handle a one-in-100-year event. According to NASA's Rosenzweig, in New York City's Battery Park neighborhood an 8.6-foot flood height is designated as a one-in-100-year event. Superstorm Sandy reached 10.6 feet -- a one-in-500-year event. Also, erecting seawalls to protect Manhattan could simply divert the surge to other unprotected areas of the city, exacerbating flooding in those boroughs. And it's unclear what the environmental impact of such maritime structures would be on the region's fisheries and estuaries.
Adapting to the new normal will cost businesses and governments around the globe hundreds of billions, but that may be a bargain compared with the damage future Sandys and Katrinas cause. There is, however, a bright side: Business should be very good for those companies ready to rethink and rebuild our vulnerable infrastructure.
