Growing Concern Over Sea Level Rise [VIDEO]

December 8, 2013 by Tom Schueneman

Sea Levels and Safety


Researchers in Antarctica are using sophisticated equipment to drill down 500 meters below the ice shelf to measure ice loss, temperature, salinity and speed of melt. In one location measured melt rates of more than two inches per day have been observed.[read more]

Is Sea Level Rise Entering the Mainstream?

August 26, 2013 by David Hone

Sea Level Rise

Mid-August is never a great time for activity on the climate front, particularly not in holiday bound Europe. Perhaps the “highlight” of the week was the leak of a late draft of the upcoming Summary for Policymakers of the IPCC WG1 5th Assessment Report.[read more]

Book Review: 'High Tide on Main Street' by John Englander

August 17, 2013 by David Hone

Threat of Rising Seas


The tag line for "High Tide on Main Street" is “Rising Sea Level and the Coming Coastal Crisis“ and pretty much describes the story that unfolds even from the very early pages, although this book charts a somewhat different course, at least in the first half.[read more]

Sea Level Rise: Holding Back the Ocean

August 14, 2013 by Lou Grinzo

The hideously high cost of the climate change impacts we’ve already locked in and continue to magnify with business as usual, which is to say, too bloody high and still growing emissions. Another major component is the latency of human systems.[read more]

Sea Level Rise: Adaptation for the San Francisco Bay Area

Folding Water

The Golden Gate tidal gauge has recorded an 8 inch (20.3 cm) rise in sea level in San Francisco Bay over the past one hundred years. Projections indicate a possible 11 to 19 inch rise over 2000 levels by mid-century and as much as 30 to 55 inches by 2100.[read more]

Climate Change and Shrinking Homelands


According to Kenneth G. Miller, professor of earth and planetary sciences, Rutgers University, the natural state of the earth with present carbon dioxide levels is one with sea levels about 20 meters higher than at present.[read more]

groundwater depletion

Depletion of groundwater reserves has more than doubled in recent decades as a result of population growth and the increased demand on groundwater reservoirs for drinking water and the irrigation of croplands.[read more]

Ocean Thermal Energy Conversion a Silver Bullet for Climate Change?

March 27, 2013 by Jim Baird

silver bullet for climate change?

Ocean Thermal Energy Conversion offers a reprieve, converting the surface heat that powers tropical storms to mechanical energy and moves many times more surface heat to colder, deeper, water.[read more]

One of the most important and threatening risks of climate change is sea-level rise. The mechanisms are well understood, and the direction of changes in sea-level is highly certain.[read more]

US East Coast Hit By Historic Sea Level Rise

November 30, 2012 by A Siegel

Hurricane Sandy and a series of noreasters have combined with an apparently unprecedented one year jump in sea level to cause a wave of destruction on the U.S. east coast. The one year change of the average sea level of the North Atlantic ocean from fall 2011 to fall 2012 is about 32mm which absolutely dwarfs the computed trend of 1.7 mm...[read more]

North Carolina Bill Would Require Coastal Communities To Ignore Global Warming Science

June 1, 2012 by Joseph Romm

Some North Carolina GOP legislators want to stop the use of science to plan for the future. They are circulating a bill that would force coastal counties to ignore actual observations and the best science-based projections in planning for future sea level rise.King Canute thought he had the power to hold back the tide (in the...[read more]

Dispatch from Kiribati: Can you "see" sea level rise?

May 2, 2012 by Simon Donner

Tarawa, Kiribati - This is my fifth time visiting Kiribati for research. I'm here working on a coral monitoring project together with my colleagues at the local government. For more, check out my Scifund site, which is dedicated to raising funds for the in-country side of the coral research. People at home often ask whether I have seen...[read more]

Time to Sell That Ocean Front Property? New Study on Sea Level Rise

June 20, 2011 by Scott Edward Anderson

  Could Calvin Be Underwater?The rate of sea level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years, according to a new study published this week in the journal Proceedings of the National Academy of Sciences (PNAS). The study suggests a consistent link between changes in global mean...[read more]

Coastal studies experts: “For coastal management purposes, a [sea level] rise of 7 feet (2 meters) should be utilized for planning major infrastructure”

November 14, 2010 by Joseph Romm

The New York Times has a splashy front-page story on some of the latest research on sea level rise today.  The graphics above make clear the paper gets a big part of the story right — the latest science says we are facing 3 to 6 feet of sea level rise this century. Kudos to the NYT for featuring such an important story.  Given...[read more]

The real issue

October 28, 2010 by David Hone

As CO2 levels in the atmosphere continue to rise (and given the current state of global action they could quite possibly go on rising for much of this century) we hear a great deal about storms and droughts but not a huge amount about the really difficult issue that most countries face, rising sea levels.[read more]
