Sea Levels Rose Two Feet This Summer in U.S. East

As if to show the world scientists that they don't have all the answers yet, the sea levels unexpectedly rose two feet (60 cm) this summer along the US East Coast.  While the first culprit one would think of would be global warming, the Arctic ice cap is melting at a rapid rate, and the second might be Atlantic storms pushing the water towards the coast, it seems neither of these applies.
The Center for Operational Oceanographic Products and Services at the U.S. National Oceanic and Atmospheric Administration(NOAA) has determined that a combination of slowing of the Gulf Stream and an early start to winds coming from the northeast Atlantic have served to pile the water up along the coast.
The Gulf Stream is an important current that originates in the tropics and carries warm water northward, then veers across towards Europe.  It is an important factor in modifying the climate of the lands that it is near and well as being a crucial cog in the world ocean circulation.

"Why did the Gulf Stream slow down? Why did the fall wind pattern appear earlier?" NOAA's Edwing said. "We don't have those answers."

These unanswered questions serve to remind us that the Earth's atmosphere and oceans are extremely complex.

Two feet!? Wouldn't that put some areas underwater (if I remember Al Gore correctly anyway)?

Amy,

The description of the sea level raising two feet can be confusing.  The rise in tides on the east coast was in June and July, and they don't quite know why.  The damage is to the erosion of beaches and homes that are built in proximity to shore lines.  I saw some pictures of homes on stilts that suffered damage. 

In Al Gores book, he addresses permanent, not seasonal rising sea levels that inundate and alter coast lines and flood cities.  In his book there are pictures of places like Florida where half of the state would be reclaimed by the sea. In the Netherlands which is a lowland country would be devastated.  The predictions for San Francisco Bay in his book prompted the commission I related above.  In Schanghai 40 million people would be displaced and in Calcutta and Bangladesh 60 million. In Manhattan if sea levels rise 20 feet the site of the World Trade Center Memorial would be underwater.

It appears we will not be able to stop glacial melt and subsequence sea levels rising, but we can prepare now for the undeniable future.

The San Francisco Bay Conservation and Deveopment Commission is taking a pro-active approach with the inevitibility of sea levels rising. They issued a report in 2008 with some goals and objectives including the development of sea level maps that detail the areas most likely to be inundated around the San Francisco Bay and as far north is Suisun Marsh which is approximately 50 miles from San Francisco and 20 miles north of San Pablo Bay that connects the San Francisco Bay with the northern extremeties of the bay area.

The maps will show the predictions in sea levels rise within 50 years and within 100 years.  They will reflect scientic consensus on the highest rates of sea level rise expected within the scenario that reflects current global rates.

It can help determine the the socio-economic and ecological impact of the changes:

1) social and ecomonic value of existing and permitted built resources

2) Cost of protecting the resources through the construction of seismically safe levees and seawalls

3) Ecological value of natural resources to be impacted

4) cost of acquring upland areas to allow the wetlands to migrate as the sea levels rise

Now is the time to plan for the inevitibility of sea levels rising, so the protection of coastlines,  inland waterways, and wildlife sanctuaries can be preserved.

If the Gulf Stream slows down, that is due to Climate change though, there for if the Gulf stream and the currant are the cause for the rise then the cause is Climate change.

In addition it would mean that the Gulf stream is collapsing faster then we anticipated, wish will result in an Ice age from Europe and higher precipitation in North Africa. 

It would also mean that the average temperature of the oceans is still rising and that the global average is rising as well.

Ice Age in Europe and Desertification in North America would be the result.

More Typhoons for us here in Asia and more natural disasters as well.

Agriculture will be a challenge, more so then it is already and famines are imminent, and this even in North America and Europe.

Wait till el Nino hits, imagine the 2010 olympics without snow according to weather experts

I went to the New Jersey shore this summer.  Can't say I noticed the difference, but I'm always following the weather, and the coastal issues.  They do matter to us in NJ, NY, and PA, for example.

Desertification is already here in North America. : (

Some reports say that 40% of the rangeland in the United States is barren, but a lot of it so far is from improper land use, not climate change. So imagine what the impact could be with both systems effecting the land.

Here in the U.S., many become used to a landscape that is barren and don't realize it was not like that originally.   Praries were lush with all kinds of grasses and wildflowers, but they have turned to dust.  Greece used to be covered with trees but they were harvested faster than they could replenish themselves, so how do we percieve Greece now?  We think its suppose to covered in rocky, barren land, but it's not. 

The devastation in the wake of climate change is almost too grim to imagine

When it comes to Deserts and desertification the articles above may help and they do give a lot of links on the subject as well.

Barry,

What is the plan if there isnt any snow?  This is unprecedented.

Thanks for this post, Barbara.  I hope it's only temporary rather than permanent rise.  Regardless, the world needs to work together to stem the potential devastating ramifications of global warming.

Desertification is almost always a result of cooler temperatures globally.  When will anyone admit we are going into an Ice Age?... By the way, a 2 ft rise in sea level does not necessarily mean anything.  The earth is not a perfect sphere, and there are variations of up to 50 ft naturally.  No cause for alarm.

This October in Ohio is just strange! We are having no Indian Summer this year! The temps are 20 degrees lower then what it should be at this time of year! Also we had the coolest summer on record!  I just wonder if the slowing down of the gulf stream does not have something to do with this?? Comments? Feed back? Other?Thank you.William
