Scientists: Rising seas will flood historic sites

  • Scientists: Rising seas will flood historic sitesStory Highlights
  • Scientists: Rising seas will likely swamp Jamestown, Virginia
  • Other sites threatened: Wall Street, Silicon Valley, the Outer Banks
  • Oceans are expected to rise by about 39 inches over the next century
(AP) -- Ultimately, rising seas will likely swamp the first American settlement in Jamestown, Virginia, as well as the Florida launch pad that sent the first American into orbit, many climate scientists are predicting.

Rising waters will flood the first American settlement of Jamestown within a century, scientists predict.

In about a century, some of the places that make America what it is may be slowly erased.

Global warming -- through a combination of melting glaciers, disappearing ice sheets and warmer waters expanding -- is expected to cause oceans to rise by one meter, or about 39 inches. It will happen regardless of any future actions to curb greenhouse gases, several leading scientists say. And it will reshape the nation.

Rising waters will lap at the foundations of old money Wall Street and the new money towers of Silicon Valley. They will swamp the locations of big city airports and major interstate highways.

Storm surges worsened by sea level rise will flood the waterfront getaways of rich politicians -- the Bushes' Kennebunkport and John Edwards' place on the Outer Banks. And gone will be many of the beaches in Texas and Florida favored by budget-conscious students on Spring Break.

That's the troubling outlook projected by coastal maps reviewed by The Associated Press. The maps, created by scientists at the University of Arizona, are based on data from the U.S. Geological Survey.

Few of the more than two dozen climate experts interviewed disagree with the one-meter projection. Some believe it could happen in 50 years, others say 100, and still others say 150.

Sea level rise is "the thing that I'm most concerned about as a scientist," says Benjamin Santer, a climate physicist at the Lawrence Livermore National Laboratory in California.

"We're going to get a meter and there's nothing we can do about it," said University of Victoria climatologist Andrew Weaver, a lead author of the February report from the Intergovernmental Panel on Climate Change in Paris. "It's going to happen no matter what -- the question is when."

Sea level rise "has consequences about where people live and what they care about," said Donald Boesch, a University of Maryland scientist who has studied the issue. "We're going to be into this big national debate about what we protect and at what cost."

This week, beginning with a meeting at the United Nations on Monday, world leaders will convene to talk about fighting global warming. At week's end, leaders will gather in Washington with President Bush.

Experts say that protecting America's coastlines would run well into the billions and not all spots could be saved.

And it's not just a rising ocean that is the problem. With it comes an even greater danger of storm surge, from hurricanes, winter storms and regular coastal storms, Boesch said. Sea level rise means higher and more frequent flooding from these extreme events, he said.

All told, one meter of sea level rise in just the lower 48 states would put about 25,000 square miles under water, according to Jonathan Overpeck, director of the Institute for the Study of Planet Earth at the University of Arizona. That's an area the size of West Virginia.

The amount of lost land is even greater when Hawaii and Alaska are included, Overpeck said.

The Environmental Protection Agency's calculation projects a land loss of about 22,000 square miles. The EPA, which studied only the Eastern and Gulf coasts, found that Louisiana, Florida, North Carolina, Texas and South Carolina would lose the most land. But even inland areas like Pennsylvania and the District of Columbia also have slivers of at-risk land, according to the EPA.

This past summer's flooding of subways in New York could become far more regular, even an everyday occurrence, with the projected sea rise, other scientists said. And New Orleans' Katrina experience and the daily loss of Louisiana wetlands -- which serve as a barrier that weakens hurricanes -- are previews of what's to come there.

Florida faces a serious public health risk from rising salt water tainting drinking water wells, said Joel Scheraga, the EPA's director of global change research. And the farm-rich San Joaquin Delta in California faces serious salt water flooding problems, other experts said.

"Sea level rise is going to have more general impact to the population and the infrastructure than almost anything else that I can think of," said S. Jeffress Williams, a U.S. Geological Survey coastal geologist in Woods Hole, Mass.

Even John Christy at the University of Alabama in Huntsville, a scientist often quoted by global warming skeptics, said he figures the seas will rise at least 16 inches by the end of the century. But he tells people to prepare for a rise of about three feet just in case.

Williams says it's "not unreasonable at all" to expect that much in 100 years. "We've had a third of a meter in the last century."

The change will be a gradual process, one that is so slow it will be easy to ignore for a while.

"It's like sticking your finger in a pot of water on a burner and you turn the heat on, Williams said. "You kind of get used to it."

I seem to remember 30 years ago they were predicting the next ice age.....

when every scientist agrees then I'll believe...

Watch out, he'll throw back at you the "there's consensus and it's settled science" ball. Cause you know when that happens that means it's all over, once science has reached consensus and settled on the science there's no use in looking at any refuting evidence cause you know, it's settled and all that. :whatever:

One of the scare stories they use to further MMGW theory is that the Great Lake's water level is dropping at a rate unseen since I don't know like forever. Hmmm, I wonder why it's dropping?

Could it be maybe NOT global warming?

Great Lakes Losing 2.5 Billion Gallons Per Day Due to Manmade Drain Hole Near Detroit

New Research Finds St. Clair River Draining Water from Lakes Huron, Michigan

at Triple Rate Originally Thought

PARIS, ONTARIO, Canada, Aug. 14 /PRNewswire-USNewswire/ -- Two years after specialists first linked declining water levels in Lakes Michigan and Huron to U.S. and Canadian navigation dredging, riverbed mining and shoreline alteration projects near Port Huron and Sarnia, research released Tuesday finds that the river "drain hole" is sucking away triple the amount of water previously estimated--causing widespread ecological harm throughout the middle Great Lakes.

The updated findings released by the Georgian Bay Association (GBA) show that the drain hole in the St. Clair River is causing the Michigan-Huron system to hemorrhage 2.5 billion gallons of water a day--more than triple the 845 million gallons documented two years ago by a consulting firm studying the impact of the U.S. Army Corps's dredging in the river.

According to the article the sky is already falling and there is nothing we can do about it.:whatever:

Did anyone ever ask them where the water came from that became the glaciers. It is not new water that came from MARS or outer space. The water is churned up blown around and or evaporates and is redistributed all the time. Some turns to Ice, snow and rain.

So the net amount of new rain or water or melted ice is probably not all that great plus minor seasonal changes and normal yearly variations .

The earth flies around the sun like a bat out of heck and rotates at a high speed causing atmospheric changes all the time as winds move around our planet.

I don't think there is a lot we do to change it very much or predict what it might do 10-20 years from now..

I saw a show on The History Channel about global warming / glacial meltdown last night. They said the glaciers in the National Parks have been around for something like 10,000 years. They said the ice sheet / glaciers in the Antarctic has been around for something like 500,000 years. This begs the question, does this mean that there was no glaciers 600,000 years ago? While humans may be contributing a small percentage to the global warming issue, I have to believe that a majority of the warming is something that is a phase the Earth goes thru periodically. Ya gotta remember, the Earth is 4.5 billions years old, and there have been climatic events on it that even the scientists don't know about.
The other thing that one of the scientists mentioned on the TV program was this little fact: If we, the world, immediately stopped emitting 'greenhouse' gases today, the atmosphere would continue to warm, the glaciers would continue to melt and the oceans would continue to rise for the next 30 -50 years.
So, whatever is gonna happen is gonna happen and we can't control it.

I heard an interesting phrase yesterday; "global warming denier"....obviously borrowing from the term "holocaust denier". Apparently this science is now so settled that anyone that disagrees has reached the level of nazisim. Facinating.

No change in political climate

By Ellen Goodman | February 9, 2007

I would like to say we're at a point where global warming is impossible to deny. Let's just say that global warming deniers are now on a par with Holocaust deniers, though one denies the past and the other denies the present and future.

We are just a spec in the universe and I think we have little control over what it does next year and beyond.
And I don't think we can predict what it will do next year let alone 20 years fom now.

Around here the weatherman or woman can't predict for sure if it will rain tomorrow.

VIP is right. We can't predict if/how much the planet will warm in the future. But global warming is also a measurable phenomenon, and it certainly does appear that the Earth has been warming for some time. But so what? Ancient glacial ice, tree rings and various other indicators prove that we've gone through countless warming and cooling cycles over the last several billion years. So what's different about this cycle? Simple: bad science and political nonsense have some people believing that for the first time in all those billions of years, humble human beings can actually do something about it. Balderdash!!!! What we can do is spend thousands - no wait - millions - no wait - billions, okay trillions of dollars only to find out just how helpless and ineffectual we really are. I don't know about you, but I don't have that kind of money.

Perhaps it's this rather short range view that has contibuted to the problem?

Bingo! I don't think there is any denying that there is global warming. I don't believe, however, that it is a product of human activities and I also don't believe all the doom and gloom. This is just a political and ecomomic agenda. Besides, I live in the high desert, 2,389 ft above sea level. More water is good.
