Sea Level Rise - US

Primary tabs

This working group is focused on discussions about sea level rise.

The purpose of this working group is to discuss what is causing the rise in sea level, how to reduce the rate at which the seas are rising, and how to mitigate the impact that sea level rise is having and will have on our coastal communities.

When Rising Seas Transform Risk Into Certainty

thebulletin.org - by Dan Drollette Jr. - June 9, 2017

According to a new study published on Wednesday by researchers from Princeton and Rutgers universities, rare floods will soon become the norm for cities like New York, San Francisco, San Diego, and Seattle, as well as entire states such as Florida and Hawaii. On average, this means a 40-fold increase in the occurence of flood, unless humanity soon cuts back on the amount of carbon we pump into the atmosphere.

Scientists Just Documented a Massive Recent Melt Event on the Surface of Antarctica

washingtonpost.com - by Chris Mooney - June 15, 2017

Scientists have documented a recent, massive melt event on the surface of highly vulnerable West Antarctica that, they fear, could be a harbinger of future events as the planet continues to warm.

In the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the largest floating ice platform on Earth, developed a sheet of meltwater that lasted for as long as 15 days in some places. The total area affected by melt was 300,000 square miles, or larger than the state of Texas, the scientists report.

That’s bad news because surface meltin g could work hand in hand with an already documented trend of ocean-driven melting to compromise West Antarctica, which contains over 10 feet of potential sea level rise.

Scientists Say the Pace of Sea Level Rise Has Nearly Tripled Since 1990

A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway.

“We have a much stronger acceleration in sea level rise than formerly thought,” said Sönke Dangendorf, a researcher with the University of Siegen in Germany who led the study along with scientists at institutions in Spain, France, Norway and the Netherlands.

Atlantic City and Miami Beach: two takes on tackling the rising waters

The Irish Pub near Atlantic City’s famed boardwalk doesn’t have any locks on the doors as it is open 24 hours a day. So when Hurricane Sandy crunched into what was once known as the Las Vegas of the east coast in 2012, some improvisation was needed.

Regular drinkers helped slot a cork board through the frame of the door, wedging it shut and keeping out the surging seawater.

Unless the world stops burning fossil fuels that are fuelling global warming, irreversible changes in the Arctic could have disastrous effects for the people that live there and for the rest of the planet, researchers warned on Friday.

The Arctic's ecosystems are fundamentally threatened by climate change and other human activities, such as oil and gas extraction, they said in a report for the Arctic Council, an inter-governmental forum working to protect the region's environment.

Climate Change: Projecting Future Sea Level Rise

hrpdcva.gov - July 2013

Effective planning for development and infrastructure near the shore requires understanding various shore processes, including erosion, tidal patterns, and sea level change. There is a significant amount of research documenting both a sustained and long-running trend of sea level rise and that the rate of sea level rise is likely to accelerate. Therefore, it is important for local planners to understand how much sea level rise is projected to occur and at what rate. Understanding the drivers of sea level rise and how they affect sea level rise rates can also help decision-makers tasked with selecting appropriate policy and infrastructure responses.

Historic High Tides from Supermoon and Sea Level Rise Flood the Southeast Coast

washingtonpost.com - by Angela Fritz - October 27, 2015

Ocean water surged into neighborhoods on the Southeast coast on Tuesday morning during high tide, pushing gauges well beyond predicted levels. Seemingly overnight, spurred by sea level rise, we’ve entered an era where king tides compete with hurricanes in the water level record books . . .

. . . Residents are saying Tuesday’s high tide was worse than South Carolina’s “1,000-year flood” in early October.

Why Some Scientists are Worried About a Surprisingly Cold ‘Blob’ in the North Atlantic Ocean

CLICK HERE - PAPER - Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation

washingtonpost.com - by Chris Mooney - September 24, 2015

. . . we learned from the National Oceanic and Atmospheric Administration that the first eight months of 2015 were the hottest such stretch yet recorded for the globe’s surface land and oceans, based on temperature records going back to 1880. . . .

In the North Atlantic Ocean south of Greenland and Iceland, the ocean surface has seen very cold temperatures for the past eight months. . . .

. . . And while there may not yet be any scientific consensus on the matter, at least some scientists suspect that the cooling seen in these maps is no fluke but, rather, part of a process that has been long feared by climate researchers — the slowing of Atlantic Ocean circulation.
