Coral Reefs Prevent More Than $5.3 Billion in Potential Flood Damage for U.S. Property Owners
University of California, Santa Cruz

Coral reefs provide many services to coastal communities, including critical protection from flood damage. A new study led by researchers at the University of California, Santa Cruz, and the U.S. Geological Survey reveals how valuable coral reefs are in protecting people, structures, and economic activity in the United States from coastal flooding during storms.

“Ghost Forests” Expanding Along Northeast U.S. Coast
Rutgers University-New Brunswick

Why are “ghost forests” filled with dead trees expanding along the mid-Atlantic and southern New England coast? Higher groundwater levels linked to sea-level rise and increased flooding from storm surges and very high tides are likely the most important factors, according to a Rutgers study on the impacts of climate change that suggests how to enhance land-use planning.

Sea-level rise drives wastewater leakage to coastal waters
University of Hawaii at Manoa

When people think of sea level rise, they usually think of coastal erosion. However, recent computer modeling studies indicate that coastal wastewater infrastructure, which includes sewer lines and cesspools, is likely to flood with groundwater as sea-level rises.

How Could Rising Sea Level Impact the National Flood Insurance Program?
Society for Risk Analysis (SRA)

Insurance policy premiums from the National Flood Insurance Program (NFIP) allow policyholders to maintain a lower, grandfathered rate even when the risk escalates. But as coastal flooding increases due to rising sea level and more intense storms, new research published in the journal Risk Analysis suggests this grandfathered policy could lead to big losses for the NFIP. A team of experts led by Carolyn Kousky, executive director of the University of Pennsylvania’s Wharton Risk Management and Decision Processes Center, studied the effect of sea level rise on a New York City neighborhood to illustrate how grandfathered rates could impact both policyholder premiums and program revenue for the NFIP over the next 30 years. Their results project losses to the NFIP as flood risk grows in the coming decades.

When a hurricane approaches, providing a few extra hours’ notice can be the difference between life and death. Now, Penn State researchers report that applying a machine learning technique to a group of possible storm paths could help meteorologists provide more accurate medium-term forecasts and issue timely warnings to communities in the path of these potentially deadly storms.

While many models suggest that climate change will prompt a substantial number of people to leave their homes, not all research so clearly finds this is the case. Investigating cases where computer models seemed to indicate only limited impacts of climate change on people leaving rural areas, a team of researchers now suggest that the models may reveal a more nuanced circular migration pattern in areas stricken by climate change impacts.

Novel Measurement and Forecasting Systems Make ‘Weathering the Storm’ More Precise
Florida Atlantic University

In the last several decades, more than half of the deaths associated with tropical cyclones in the U.S. were due to inland flooding. Unfortunately, current forecasting capabilities are limited. Researchers are developing a warning system for more accurate and timely detection and forecasting of inland and coastal floods, under a variety of precipitation regimes. The technology will enable local and state governments to more effectively plan and respond to tropical storms.

Study reveals Missoula Floods impact on past abrupt climate changes
Woods Hole Oceanographic Institution

A new study shows for the first time how massive flood events in the eastern North Pacific Ocean—known as the Missoula Floods—may have in part triggered abrupt climate changes in the Northern Hemisphere during the last deglaciation (approximately 19,000–11,700 years ago). The findings are contrary to the long held notion that cooling was primarily driven by changes in North Atlantic circulation.

Irvine, Calif., Jan. 21, 2020 – Community collaboration and high-resolution maps are key to effective flood risk management, according to civil engineers and social scientists at the University of California, Irvine and other institutions. In a study published recently in the American Geophysical Union journal Earth’s Future, the researchers report on a successful new process called “collaborative flood modeling” for addressing the increasing threat of rising waters brought on by climate change, aging infrastructure and rapid urban development.
