How High Could the Tide Go?

By JUSTIN GILLIS


BREDASDORP, South Africa — A scruffy crew of scientists barreled down a dirt road, their two-car caravan kicking up dust. After searching all day for ancient beaches miles inland from the modern shoreline, they were about to give up.

Suddenly, the lead car screeched to a halt. Paul J. Hearty, a geologist from North Carolina, leapt out and seized a white object on the side of the road: a fossilized seashell. He beamed. In minutes, the team had collected dozens more.

Using satellite gear, they determined they were seven miles inland and 64 feet above South Africa’s modern coastline.

For the leader of the team, Maureen E. Raymo of Columbia University, the find was an important clue as she tries to determine just how high the oceans might rise in a warmer world.

The question has taken on new urgency in the aftermath of Hurricane Sandy, which caused coastal flooding that scientists say was almost certainly worsened by the modest rise of sea level over the past century. That kind of storm tide, the experts say, could become routine along American coastlines by late in this century if the ocean rises as fast as they expect.

In previous research, scientists have determined that when the earth warms by only a couple of degrees Fahrenheit, enough polar ice melts, over time, to raise the global sea level by about 25 to 30 feet. But in the coming century, the earth is expected to warm more than that, perhaps four or five degrees, because of human emissions of greenhouse gases.


Experts say the emissions that may make a huge increase of sea level inevitable are expected to occur in just the next few decades. They fear that because the world’s coasts are so densely settled, the rising oceans will lead to a humanitarian crisis lasting many hundreds of years.

Scientists say it has been difficult to get people to understand or focus on the importance, for future generations, of today’s decisions about greenhouse gases. Their evidence that the gases represent a problem is based not just on computerized forecasts of the future, as is commonly believed, but on what they describe as a growing body of evidence about what occurred in the past.

Dont' miss the rest of this article and the slide show of prehistoric beaches. The is fascinating stuff.

Granny says it gonna cover the tops o' the mountains...

... 15 cubits deep (22.5 ft.)...

... just like it did durin' Noah's flood.

 

You're a nut...........

 

I doubt it. In many instances it is caused by the land rising from geologic forces over millions of years. In many places in the world you can find sea shells on top of mountains within a few kilometers from the coast. The land used to be underwater, but then it slowly got pushed upwards.

 

that would've been considered in the selection of site locations, that's routine with archeologists...take the target date you want to research, match that with estimated sea levels at that time period and find the most likely search areas...

 

In eastern NC they say.. the tide was so high the sharks et the collards.

 

Oh hell.....I thought you wanted to talk about Alabama winning a third national championship.....now THAT's exciting...

As far as sea levels creeping up....it is called an INTERGLACIAL Margot......when the ice caps STOP receding and the sea level STOPS climbing, then we are in REAL trouble. You think a few inches of water is a problem for Manhattan....how about 3 miles of ice..???

Been going on over and over for millions of years Margot...all without the help of my old GMC Yukon..... Relax

my house is at 1385 feet elevation and I just found some sea shells last week..oh wait maybe the kids dropped them there when they were playing around

The author of this article blames flooding on deforestation:

Dr. Albert Einstein took HAB Theory seriously. Fifty years from now this could be generally accepted as the best explanation for this phenomena…… when it isn't caused by the kids!

All deserts are not man made...

 

50 years ago people said the seas would be raised by 90 feet by the year 2000..guess what? they are still at the same spot now as they were back then..so in 50 years from now they will be the same..but scare tactics make good news..for the misinformed

 

Chicken Little hysterics will find something else next year.. What they won't do is pursue an education.

 

So…. what do you think about the stats given?

Would you say that it might be false about 293 cubic miles of ice being added to the central region of Antarctica in many years?

"At a symposium of the Union of Geodesy and geophysics, Dr. Pyyotor Shoumsky reported that the south polar ice cap was growing at a minimum rate of 293 cubic miles of ice annually. To put that number in perspective, Lake Erie contains only 109 cubic miles of water. Thus, a volume of ice forms on top of the existing ice at Antarctica each year which is almost three times the volume of water in Lake Erie!" (Gershom Gale)

Yes it is false

Care to offer a citation for that please

 

Here is another source for essentially the same statistic!

"Let us consider Antarctica for a moment.
We have already seen that it is big. It has a land area of 5.5
million square miles, and is presently covered by something in excess
of seven million cubic miles of ice weighing an estimated 19
quadrillion tons (19 followed by 15 zeros). What worries the
theorists of earth-crust displacement is that this vast ice-cap is
remorselessly increasing in size and weight:'at the rate of 293 cubic
miles of ice each year--almost as much as if Lake Ontario were frozen
solidly annually and added to it."(Graham Hancock, Fingerprints of
the Gods, page 480).

 

Yes, I've found oceanic fossils embedded in iron ore on a mountain top. This doesn't imply that the mountain top was once below sea level. A large chunk of the Southeastern United States is known to have crashed into the main continent many years ago. The fossils that I found embedded in mountain top stone were probably deposited there long before that land mass collided with the continental US and became a mountain.

 

being that there were no pc's back in the early 60s and wikipedia didnt excist back then its kind if hard to google it...this is what we were told in science classes back then...but it still never happened...wrong then and wrong again

 

If you are citing your own childhood memories, then you shouldn't be surprised to find errors within the citation.

 

thats the best insult you can do?..cmon..do it right

 

It was not intended as an insult. It was merely a statement of fact.

 

Sorry a Von Danieken retread is not a citation

 

Sorry I was also taking science classes in the 60s Nowhere was there ever a claim of a 90 foot sea level rise by the year 2000

 

Sea level during the Holocene has been both higher and lower than it is now. It has been rising since the end of the Little Ice Age.

i was told this by two extreme teachers who then werent labeled liberals but their views were weird to me..they were hippie types back then..they said this is what scientists were predicting ..just didnt make sense then and still doesnt..
