Sea Level Rise

Accelerated erosion

View Sea Level Rise Gallery

There will always be beaches, but sea level rise will ensure that they will not be in the same place in the future. The beaches will still exist throughout this change, but many of the buildings may not. Efforts to save development, however do threaten beaches, such as shoreline armoring structures.

Although relative amounts of rise may seem very small, only a few millimeters per year, the cumulative effect of these small rises each year over a long period of time (100+ years) causes major problems. Accelerated rates of erosion are attributed to sea level rise and erosion causes large economic losses around the world each year due to the close proximity of buildings and critical infrastructure. This includes transportation systems, gas and oil lines as well as electricity lines and power plants.

Most developed coasts and beaches have buildings very close to the ocean leaving little room for the ever-expanding ocean. The future effects of sea level rise on coastal civilization over the entire world are of great concern. Over half of the world’s population lives within 100 km of the coast. Over the next 50 years, damage due to coastal development will be devastating, but if the rate of sea level rise increases, the results could be catastrophic. This issue threatens areas from New York City in the United States to the Pearl River Delta in China to the Maldives.

The world map below allows you to see elevations of coastal areas. Areas in red are the lowest in elevation and are most prone to flooding. Check out Manhattan in New York City. If you think the situation there looks dire, be sure to check out the effects of a 2 m rise in sea level on Pearl River Delta in China, home to more than 40 million people. Map courtesy of

Human Activities Produce More Carbon Dioxide Emissions Than Do Volcanoes

On average, human activities put out in just three to five days, the equivalent amount of carbon dioxide that volcanoes produce globally each year.

Climate change: How do we know?

The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years. In the meantime, the fate of the only international agreement that sets binding targets for curbing greenhouse gases is hanging by a thread…

Arctic Melt Raises Sea Levels and Reinforces Global Warming

If you want to see global warming’s signature, look to the Arctic. Up north, the air is warming and the ice is melting. For two decades, scientists have predicted these things would happen as the Earth warms, and now we see that the Arctic is changing much as expected. Melting Arctic ice is also contributing significantly to sea level rise.

Rising sea levels endangering Australia’s World Heritage-listed Kakadu wetlands

A study released by Australia Government, finds that Kakadu National Park, a protected northern territory, half the size of Switzerland, is one of Australia’s “natural ecosystems most vulnerable to the impacts of climate change”, with higher oceans being a “serious risk” to its ecosystem.

Climate Change Impacts in China

The received wisdom used to be that climate change would have relatively little impact on China. But that views seems outdated.

Australian Sea levels Set To Rise By Up To a Metre: Report

Sea levels will rise by more than three feet by the end of the century making severe coastal flooding a common factor of life in Australia if urgent action is not taken to limit climate change, a key report by a panel of climate scientists has found.

Seismic Shift? As Bahamas islands Sink, One Island Mysteriously Rises

All the islands in the Bahamas were thought to be slowly sinking, but now scientists made a surprise discovery of recent tectonic activity in a region that was up to now considered stable, finding one quirky isle going against the crowd.

Seaports Need a Plan for Weathering Climate Change, Researchers Say

A warming planet means rising oceans, but the majority of seaports around the world are unprepared for the potentially damaging impacts of climate change in the coming century, according to a new Stanford University study.

Is climate science disinformation a crime against humanity?

November 2nd, 2010

While it may be reasonable to be somewhat sceptical about climate change models, disinformation about the state of climate change science is extraordinarily, if not criminally, irresponsible, because the consensus scientific view is based upon strong evidence that climate change is already being experienced in the world, and may have potentially harsh effects upon tens of millions of people in the future.

Troubled Islands: Hurricanes, Oil Spill and Sea Level Rise

October 30th, 2010

The Chandeleur Islands, are remote, tenuous strips of sand that have served as surf breaks for the steadily sinking Biloxi Marsh. Some islands could disappear entirely in coming decades, exposing huge swaths of marshland to the waves of the open sea.

Underwater Robot to Explore Antarctic Ice Shelf

October 19th, 2010

Ice shelves are floating platforms of ice that cover almost half of Antarctica’s coastline. Until recently, scientists have had limited ability to access ice-covered waters, and the research team’s use of a high-tech robot aims to change that.

Solar Power in the Maldives

October 7th, 2010

With hardly any land more than 8 feet above sea level, thus particularly vulnerable should seas rise several feet by the end of the century, the Maldives stands at the front line of climate change, and has announced plans to green its energy sector and pledged under the Copenhagen Accord to become carbon neutral by 2020.
