Glacial Rebound: The Not So Solid Earth

nasa.gov - August 26, 2015

When you fill a sink, the water rises at the same rate to the same height in every corner. That's not the way it works with our rising seas.

According to the 23-year record of satellite data from NASA and its partners, the sea level is rising a few millimeters a year -- a fraction of an inch. If you live on the U.S. East Coast, though, your sea level is rising two or three times faster than average. If you live in Scandinavia, it's falling. Residents of China's Yellow River delta are swamped by sea level rise of more than nine inches (25 centimeters) a year.

These regional differences in sea level change will become even more apparent in the future, as ice sheets melt. For instance, when the Amundsen Sea sector of the West Antarctic Ice Sheet is totally gone, the average global sea level will rise four feet. But the East Coast of the United States will see an additional 14 to 15 inches above that average.

Reducing the greenhouse gas emissions that cause climate change could prevent tens of thousands of deaths and hundreds of billions in economic losses in the United States, according to a new study by the Environmental Protection Agency.

CLICK HERE - STUDY - Changing global patterns of urban exposure to flood and drought hazards

Summary:  A heads-up to New York, Baltimore, Houston and Miami: a new study suggests that these metropolitan areas and others will increase their exposure to floods even in the absence of climate change.  Their work is published in Global Environmental Change. . . .

. . . "Through land change, bank protection, channelization, and other means, urbanization can also alter the geomorphology of river channels and floodplains, which in turn may contribute to increased risk of flooding."

"Our findings suggest that future urban expansion in flood and drought prone zones will at least be as important as population growth and economic development in increasing their exposure," the researchers add.

"With climatic changes, this exposure is only expected to increase in the future. Thus, proper planning and financing in fast growing cities today will be critical in mitigating future losses due to floods and droughts."

. . . Problems like localized flooding will become all the more urgent as climate change progresses. But the threat to each neighborhood is different, depending on where it is located relative to the city's 500-plus miles of coastline, and factors like socio-economic conditions, building stock, and critical infrastructure.

City officials are far from indifferent. Its strategy, in a nutshell, is to gradually strengthen the coastline, upgrade building stock, and protect critical infrastructure. Next week on Earth Day, April 22, the city plans to release a major progress report, the first in four years, on its multi-pronged sustainability framework, known as PlaNYC. As in the past, the report is expected to include discussion of climate resiliency, that is, the city's ongoing and developing preparations to manage for the effects of climate change.
