BOSTON, July 26 (Reuters) – Rising sea waters may threaten U.S. coastal cities later this century, while the Midwest and East Coast are at high risk for intense storms, and the West’s water supplies could be compromised.

These are among the expected water-related effects of climate change on 12 cities across the nation over the remainder of the century, according to a study released on Tuesday by the Natural Resources Defense Council (NRDC), a leading environmental group.

‘A lot of people think of climate change in the global context, but they don’t think about the local impact climate change might have, particularly on water-related issues,’ said Steve Fleischli, a senior attorney with NRDC’s water program.

In the coming decades, Miami, New Orleans and Norfolk, Virginia were expected to be the coastal cities hardest hit by flooding and storm surges due to rising sea levels, the group said.

In Boston, where the city’s airport is flanked by water, historic landmarks and critical transportation infrastructure were at a greater risk of flooding due to rising sea levels.

Los Angeles, Seattle and San Francisco will face similar danger from rising waters, according to the report.

The NRDC said climate change was making heat waves, floods and droughts more severe. […]
