Sea Level Rise ‘Worst Case Scenario’

Surge picture from November 9, 2007 (Image courtesy of NOC)

A paper published this week in Environmental Research Letters by NOC scientist Dr. Svetlana Jevrejeva provides new information about the probability of a sea-level rise reaching of 180cm by 2100. In this study Dr. Jevrejeva and colleagues explore the range of possible sea level rise by 2100 and add new data to the estimates currently available. Previously an upper limit, or ‘worst case scenario’, has not been possible to calculate, but this new study now looks beyond the previous data available to provide a more complete picture. The estimate of 180cm as the upper limit is thought to be a low probability, only a 5% chance, but this worst case scenario sea level rise projection cannot be ruled out, given past climate proxy observations and current model limitations. With sea levels continuing to rise in the 21st century, the impact assessment, risk management, adaptation strategy and long-term decision making in coastal areas depend on up to date future projections of sea levels. This work is important step forward, with the latest Intergovernmental Panel on Climate Change (IPCC) assessment report indicating sea level projections spanning a likely range (66% increase) only, which means a 1/3 of future sea level rise may lie outside the stated uncertainty ranges by IPCC. Coastal engineers, such as those planning improvements to the London Thames barrier, need to look at this new data

Sea-Level-Rise Forecasts Major Climate Impact to Pacific Islands

Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research, according to a new U.S. Geological Survey report. A team led by research oceanographer Curt Storlazzi of the USGS Pacific Coastal and Marine Science Center compared passive "bathtub" inundation models with dynamic models for two of the


Indonesia Building Sea Wall to Protect Jakarta

Indonesia on Thursday officially launched a $263 million project to build a giant sea wall along the coast of its capital, Jakarta, in an attempt to protect businesses and homes from flooding. Last year's rainy season brought Jakarta to a standstill, causing a river in the city to breach its banks and swamp the central business district, leaving thousands stranded and causing $580 million in damage. With 40 percent of Jakarta already below sea level


NOAA: US to See More Floods from Sea Level Rise

Most of U.S. coast may see 30 or more days a year of floods up to 2 feet above high tides. By 2050, a majority of U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year due to dramatically accelerating impacts from sea level rise, according to a new NOAA study, published in the American Geophysical Union’s online peer-reviewed journal Earth’s Future. The findings appear in the paper From the Extreme to the Mean: Acceleration and Tipping Points


Accelerating Sea Level Rise Threatens Coasts

Sea level rise in the past two decades has accelerated faster than previously thought in a sign of climate change threatening coasts from Florida to Bangladesh, a study said on Wednesday.   The report, reassessing records from more than 600 tidal gauges, found that readings from 1901-90 had over-estimated the rise in sea levels. Based on revised figures for those years, the acceleration since then was greater than so far assumed.  


Drilling to Start in Iran’s Caspian Blocks

Three-dimensional seismological operations at Iranian blocks in Caspian Sea in preparation for spudding two wells are underway and drilling operations are to begin on February 1, according to PIN. Deputy minister of oil for Caspian Sea oil and gas affairs told Petroenergy Information Network that a bid is underway for choosing a foreign contractor with experience in working at deep waters and the results will be announced in two weeks.

Miami-based outfitting contractor Sea Level Marine announced its recent successful completion of a dry-dock refit of Crystal Cruises’ Serenity on May 21, 2011 at Meyer Werft yard in Hamburg, Germany.  The scope of the 14-day project was an interior renovation of all passenger accommodations on the vessel including 436 Standard staterooms, 72 Penthouses, and 33 Penthouse Suites.  Architectural design for the project was developed by II x IV Design of Toronto.


Oceans Can’t Take Any more: Researchers Fear Fundamental Change

To date, the oceans have essentially been the planet’s refrigerator and carbon dioxide storage locker.

  Our oceans need an immediate and substantial reduction of anthropogenic greenhouse gas emissions. If that doesn’t happen, we could see far-reaching and largely irreversible impacts on marine ecosystems, which would especially be felt in developing countries


Seas Could Rise 6m Even if Govts Curb Warming -Study
