Where are the effects of global warming already having a major impact? In places like South Florida and especially Miami, which faces major long-term threats from a slow but stealthy adversary: sea level rise.
In this region, sea levels already have risen by about a foot since 1880. By the end of this century, according to the latest assessment report from the Intergovernmental Panel on Climate Change, they're expected to rise by another 1 to 3 feet, and possibly as high as 5 to 6 feet.
This poses dire threats to Miami's fresh water supplies, which already are being affected by rising seas pushing saltwater into its underground aquifers.
Because South Florida sits on very porous limestone rock, the water doesnt just come up over the edge it comes in through that porous rock underneath," said Nicole Hammer Hernandez, the program manager of Florida Atlantic University's climate change initiative, in an interview with weather.com.

The bad news doesn't stop at the surface, however. Because Miami is built on a foundation largely made up of limestone -- which water passes through easily -- building higher storm surge barriers won't solve the problem of keeping seawater out. "So if you build a seawall, the wall will prevent water from coming up over that edge, but the water is still going to come in underground," she added.
That's a particularly bad omen for sensitive ecological treasures like Everglades National Park (its elevation varies from 0 to 8 feet above sea level), as it lies virtually unprotected from the expected onslaught of salt water intrusion into inland water systems.
Meanwhile, Miami's population growth hasn't stopped in recent years, rising from about 249,000 people in 1950 to more than 410,000 today, with more than 5.5 million scattered across the Miami metro area.
"Some people say, well just raise the buildings, well put everything on stilts, and we can manage that way," said Hernandez. "That solves one piece of the problem. But the other piece is, where are we going to get our fresh water from?"

Algore’s pocketbook?
Miami/SoFL sucks so much freshwater out of the aquifer that it is being replaced by saltwater filling the lowered pressure areas.
More total BS from the weather troops.
What physics are involved when the sea level rises in one place and not another?
Laboratories
UN panel meetings
Newsrooms
College lecture halls
Mars
Al Gore’s lower chakra
The Miami Shoreline was at sea level in the 1880 and is at sea level now.
Isn't the sea level equal all over the planet? If you piss in the ocean doesn't the whole planet's sea level rise accordingly?
A foot?
I'd like to see a footnote on that claim.
“Junk physics”?
Around here the weather report is adjusted up, or down every few hours. THEY DON’T KNOW WHAT THE TEMPERATURE IS GOING TO BE, IF it’s going to be windy, rainy, whatever.
Used to be before computers they reported accurately what the weather was going to be, but apparently nowadays meteorologists are simply computer printout dramatists.
Have you noticed that they just say ‘climate change’, and it’s a foregone conclusion that it’s man caused? The climate’s changing, but the ‘why’ is no longer questioned.
“Isn’t the sea level equal all over the planet? If you piss in the ocean doesn’t the whole planet’s sea level rise accordingly?”
No.

Aw gees...here we go again. Words like "possibly", "expected", "may", "could" are all weasel words that are used in articles that want to sound scholarly. And when is this supposed to happen? I do know that the sun will eventually turn into a Red Giant and will engulf the earth. I think just before that happens, the polar caps will melt and the sea levels will rise...briefly. But then, we'll all be crispy critters long before that.
Seems I remember one ex-Vice President who said climate change would bury parts of the US under three feet of water in the next 12 years. I think that was in the mid-1990's. Fact is, the Arctic ice pack is something like double its previous size this year. But then, these clowns don't want to be confused by the facts.
Perhaps it’s not the seas that are rising, but the land that is sinking from the weight of the bullshit these people are spreading.
The Weather Channel has become the Global Warming Scare Site. They are a joke. The IPCC estimates on sea level rise are also a joke, well beyond the realm of any measurements or any possible mechanism that could conceivably support their assertions. See today’s article from Watts Up With That:

We're really feeling it here in Tucson. The temperature has been below 100 for several days now. Brrr!
Here’s an idea: Tell Al and his idiotic friends that, if they hurry and remove all of the sponges in the oceans of the earth, sea levels will fall and there will be room for all that extra water when the polar caps melt.
