On Superstorm Sandy Anniversary, New York is Ranked Most Vulnerable U.S. City [Newsweek]

By Nina Burleigh for Newsweek on October 29, 2017 Superstorm Sandy slammed the coasts of New Jersey and New York five years ago Sunday, leading to 157 deaths, 51 square miles of flooding in New York City alone and an estimated $50 billion in damage. On the anniversary of that catastrophe, researchers for Climate Central have More »

NICHI Marches With New Yorkers On Super Storm Sandy Fifth Anniversary

On Saturday, October 28, NICHI gathered with thousands of New Yorkers in Brooklyn for the #Sandy5 march to remember those we lost in Super Storm Sandy five years ago, and to stand with the victims of the devastating storms that hit Puerto Rico, Texas, Florida and the Caribbean this hurricane season. The march, led by young people More »

Design concept for the New York Outer Harbor Gateway Storm Barrier.

The National Institute for Coastal and Harbor Infrastructure believes that the failure to seriously consider regional infrastructure options,  such as a NY-NJ moveable surge barrier, could have far reaching national policy implications regarding our national coastal resiliency.

 The issue is particularly important since the Army Corps of Engineers is currently initiating a study of regional options, but has not yet indicated whether movable regional surge barriers would be included as a specific option to be studied within the scope of this program.

Also, it should be noted that NYC and other metropolitan NY-NJ  coastal communities in the metropolitan area are now actively pursuing the design and construction of highly localized barrier systems that would leave unprotected large dense, often poor, urban populations, critical infrastructure and high value economic assets.  

Infrastructure spending

Bloomberg View, Sept. 16, has a terrific article on infrastructure spending:

The big guns are coming out in the battle over infrastructure spending. Larry Summers, a celebrated Harvard economist and veteran policy adviser, has a new article making the case for spending more. Ed Glaeser, a brilliant and versatile colleague of Summers’ who studies urban economics, has an article making the opposite case.

Lightship Lecture in NY Harbor

In a post-Sandy world, regional solutions are important contributions to national priorities, according to Commander Russ Bowman of the US Coast Guard Academy, who spoke at a Lightship Lecture in September, 2016.

The lecture was entitled “Rising Sea Levels, Extreme Storms and Aging Infrastructure,” and was held Monday, September 26, 2016 on the Nantucket Lightship at Pier 6 in Brooklyn, NY.

NJ – NY storm surge group formed

Mission Statement

The Metro NY-NJ Storm Surge Working Group on is an affiliation of professionals dedicated to the premise that the future protection of the greater Metropolitan Region against catastrophic flooding from ocean storm surges, climate change and rising sea levels can only be secured by a regional approach that transcends geographical and political boundaries. The region of consideration includes New York City, northern New Jersey, the lower Hudson River Valley and south-western Long Island. These interconnected regions are all especially vulnerable due to their low elevations above sea level, their densely developed urban infrastructure and the large populations at risk.

Washington DC Faces Subsidence and Sea Level Rise: Study

A new study has confirmed that the ground beneath the Chesapeake Bay is sinking, and models that the Washington, DC area is likely to subside at least six inches over the next 100 years.

The study authors point out that the subsiding land will significantly worsen the flooding the region faces from rising ocean waters due to global warming and melting ice sheets. The news confirming the rate of land sinking due to geological processes means that rising seas are a much greater threat to the region’s roads, wildlife refuges and military bases than had been previously anticipated.

Rising Sea Levels Could Decimate Sea Turtle Nests

Rising sea levels could decimate sea turtle nesting sites around the world, scientists have warned, with the largest rookery site for green turtles increasingly at risk from being swamped by seawater.

Researchers have tested the impact of seawater upon turtle eggs in an attempt to find out why so few hatchlings were emerging on Raine Island, on the fringes of the Great Barrier Reef.

Raine Island is a remote coral cay that acts as the world’s largest nesting site for green turtles – as many as 100,000 female turtles can lay eggs in the sand each summer.

India Lost 250 Sq Km to Rising Seas in 15 Years

A total of 250.21 sq km along India’s coast was lost over 15 years because of the rising sea level, according to a study by the Indian Space Research Organisation (ISRO) and Central Water Commission (CWC).

A team of 10 scientists from the Space Application Centre in Ahmedabad — a key unit of ISRO — and the CWC under the water resources ministry studied changes along the country’s 8,414km shoreline, including those of islands such as Andaman and Nicobar and Lakshadweep.

Sea Levels Might Be Rising Much Faster Than Expected. What Should New York Do to Avoid Being Swamped?

When climate scientist James Hansen informed the world this week that the seas could rise much faster than conventional wisdom conceived, his predictions conjured apocalyptic images of submerged coastal cities and waters lapping at the Brooklyn Heights Promenade. The current international target of containing global warming to a two-degree (Celsius) rise in average atmospheric temperature would be “highly dangerous,” he and 16 colleagues warn in a paper that was controversial even before its publication. Even modest warming might cause sea levels to rise ten feet in coming decades, three times the accepted maximum.

James Hansen: ‘Emergency Cooperation Among Nations’ is Needed to Prevent Catastrophic Sea Level Rise

If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible.

According to the new study—which has not yet been peer-reviewed, but was written by former NASA scientist James Hansen and 16 other prominent climate researchers—current predictions about the catastrophic impacts of global warming, the melting of vast ice sheets and sea level rise do not take into account the feedback loop implications of what will occur if large sections of Greenland and the Antarctic are consumed by the world’s oceans.
