A report from the Natural Resources Defense Council describes water threats and adaptations in a dozen American cities.

Whether it is rising sea levels, water supply shortages, or floods, many of the nation’s cities are likely to feel the burden of a warming climate through a devastating absence or an overwhelming surplus of water, according to a new report from the Natural Resources Defense Council (NRDC). The report looks at the water-related threats to a dozen American cities and describes what those cities are doing to adapt.

While national governments dither on climate change, cities — the economic nodes and population centers that will bear the financial and social brunt of climatic shifts — have been more active. In the six years since the U.S. Conference of Mayors put forward a proposal to reduce greenhouse gas emissions at the local level, more than 1,000 mayors, representing a population of 88 million people, have signed the agreement.

C40, a global network, is doing the same work among the world’s largest cities.

The group of 12 cities in the NRDC report is as diverse in geography (Homer, Alaska, to Miami, Florida) as it is in climate (sunny Phoenix, Arizona, to rainy Seattle, Washington) and population (Homer, again, and New York City). Summarized in the interactive Google Fusion Table map below, the report looks at where the future of these cities might be headed and what is being done to avoid water-related climate problems.
