I was wondering...If all these glaciers really are melting...Won't downtown miami be basically underwater in a couple of years??(random thread i know but blame discovery channel,also trying to get people to lose focus on muldoon:)). Is there a way to stop this? So many of these skyscrapers are right on the water.....

not really... i dunno if anyone's realized this. but, while everyone's been complaining and moaning about parking pedestals, i've seen the silver lining; when global warming does happen (if it ever does) and the sea waters rise, the parking pedestals will be submerged, thus, giving us the same skyline, minus parking pedestals. its a win-win situation. no more ugly pedestals (cars would be useless anyways) and we keep our scrapers.

Ironically, low-lying places like Florida and the Netherlands are in a better position to tolerate sea level rise than most places are. We have to deal with high water levels every time a hurricane hits, and already have a coastline engineered to handle it. I suspect Japan's coastline is similarly fortified against rising water (hell, I think Japan actually has structures in place to protect cities from tsunamis!). Of course, low-lying poor places, like Bangladesh, are probably screwed, because they're low and they don't have the money to build fake reinforced-earth levees that look like natural sand dunes (most people never even notice them in Miami until you point them out, but once you know what they are, they're obvious & you can't believe you never noticed them before).

In the long run, the only thing (in Miami, at least) that would change is that the little hill between the buildings and high tide line would get higher. Miami's beach is completely artificial anyway. The sand used to make it came from Jamaica. Ditto, for southwest Florida. The summer after Hurricane Andrew, the beach in Naples was about 15 feet from high tide line to people's back yards. Now, it's so wide there you could almost play football between the high tide line and the sea oats. The parade of hurricanes ~2 years ago did similar damage to the beaches in Miami... I think more than half of the beach was washed away. I'm not sure, but I think they're actually STILL rebuilding the beach in parts of Miami.

In the pictures below, you can see just how high the artificial dunes are relative to the beach itself.

I moved to Miami in Feb 1992, we lived in South Bayshore drive (or brickell bay dr.) and on August 1992 hurricane Andrew hit south florida, man i remember the ocean covering up almost first floor of the building. I experienced lots of hurricanes and every time the ocean cover up the street. People always said that in the future miami would dissapear from the map, but i hope that that day never comes..

First of all, I would like to see a credible source for the 8 inch estimate made by Gendo. I think the actual change in sea level was significantly less than this figure. Also, global sea level is going to rise very slowly for the next 100 years and will gradually accelerate until eventually (approximately 250 years from now) it will rise in a sort of massive flooding event, that is, unless we do something about it now. The science behind this is really complicated but from what I've gathered it amounts to the fact that glaciers slowly build up momentum as they slip into the ocean and the ice sheets that hold them back begin to melt.

These ice sheets have been making the news a lot lately when big chunks break off of them. When the ice sheets melt, the glaciers behind them will have nothing holding them back from slipping into the water and melting. Specifically, when the West Antarctic Ice Sheet melts, it will be impossible to stop West Antarctica's glaciers from slipping into the ocean and causing global sea levels to increase by about 20 feet. But this won't happen for several hundred years according to current estimates.

Anyways, sea level change is a long term issue. By looking at it as a short term issue we lose touch with the real reasons for trying to prevent it: not for our own good but for the good of the future inhabitants of this planet. While South Florida won't be affected by global sea level changes in the next 100 years, it will be seriously affected by droughts and the Sub-Saharan regions will probably be devastated by them. This is the real issue right now and should be at the forefront of the global warming debate.

Here is an interesting article posted only hours ago on this very topic.

Alarmist global warming claims melt under scientific scrutiny
Full Story June 30, 2007 BY JAMES M. TAYLOR
In his new book, The Assault on Reason, Al Gore pleads, "We must stop tolerating the rejection and distortion of science. We must insist on an end to the cynical use of pseudo-studies known to be false for the purpose of intentionally clouding the public's ability to discern the truth." Gore repeatedly asks that science and reason displace cynical political posturing as the central focus of public discourse.

If Gore really means what he writes, he has an opportunity to make a difference by leading by example on the issue of global warming.

A cooperative and productive discussion of global warming must be open and honest regarding the science. Global warming threats ought to be studied and mitigated, and they should not be deliberately exaggerated as a means of building support for a desired political position.

Many of the assertions Gore makes in his movie, ''An Inconvenient Truth,'' have been refuted by science, both before and after he made them. Gore can show sincerity in his plea for scientific honesty by publicly acknowledging where science has rebutted his claims.

For example, Gore claims that Himalayan glaciers are shrinking and global warming is to blame. Yet the September 2006 issue of the American Meteorological Society's Journal of Climate reported, "Glaciers are growing in the Himalayan Mountains, confounding global warming alarmists who recently claimed the glaciers were shrinking and that global warming was to blame."

Gore claims the snowcap atop Africa's Mt. Kilimanjaro is shrinking and that global warming is to blame. Yet according to the November 23, 2003, issue of Nature magazine, "Although it's tempting to blame the ice loss on global warming, researchers think that deforestation of the mountain's foothills is the more likely culprit. Without the forests' humidity, previously moisture-laden winds blew dry. No longer replenished with water, the ice is evaporating in the strong equatorial sunshine."

Gore claims global warming is causing more tornadoes. Yet the United Nations Intergovernmental Panel on Climate Change stated in February that there has been no scientific link established between global warming and tornadoes.

Gore claims global warming is causing more frequent and severe hurricanes. However, hurricane expert Chris Landsea published a study on May 1 documenting that hurricane activity is no higher now than in decades past. Hurricane expert William Gray reported just a few days earlier, on April 27, that the number of major hurricanes making landfall on the U.S. Atlantic coast has declined in the past 40 years. Hurricane scientists reported in the April 18 Geophysical Research Letters that global warming enhances wind shear, which will prevent a significant increase in future hurricane activity.

Gore claims global warming is causing an expansion of African deserts. However, the Sept. 16, 2002, issue of New Scientist reports, "Africa's deserts are in 'spectacular' retreat . . . making farming viable again in what were some of the most arid parts of Africa."

Gore argues Greenland is in rapid meltdown, and that this threatens to raise sea levels by 20 feet. But according to a 2005 study in the Journal of Glaciology, "the Greenland ice sheet is thinning at the margins and growing inland, with a small overall mass gain." In late 2006, researchers at the Danish Meteorological Institute reported that the past two decades were the coldest for Greenland since the 1910s.

Gore claims the Antarctic ice sheet is melting because of global warming. Yet the Jan. 14, 2002, issue of Nature magazine reported Antarctica as a whole has been dramatically cooling for decades. More recently, scientists reported in the September 2006 issue of the British journal Philosophical Transactions of the Royal Society Series A: Mathematical, Physical, and Engineering Sciences, that satellite measurements of the Antarctic ice sheet showed significant growth between 1992 and 2003. And the U.N. Climate Change panel reported in February 2007 that Antarctica is unlikely to lose any ice mass during the remainder of the century.

Each of these cases provides an opportunity for Gore to lead by example in his call for an end to the distortion of science. Will he rise to the occasion? Only time will tell.

not only miami but we have manhattan, Los Angeles, and a ton off other cities that might dissapear from the map, a disaster could happen in any city, now the city that we hope nothing bad ever happens is new york city, that could be a major disaster, imagine if a cat 4 or 5 hits new york city, thats pretty unlikely but u never know.

I havent bought into the global warming hype yet. So many scientist refute the claims. I also question the accuracy of air and ocean temperatures measured in the 1800's! lol
Scientists refute what claims? The claim that global warming is being caused by anthropogenic greenhouse gases is accepted by the scientific community as a whole. Any scientist who refutes this claim should be put in the same boat as the idiot scientists who promote the 'intelligent design' theory. And all scientists refuting the claim that global warming, caused by humans or otherwise, has occurred should be taken on this boat and then thrown overboard. The numbers are there for anyone to interpret and it should be extremely obvious to qualified scientists that global warming has occurred.

Now I heard that the sea level will only rise 10'' in the next century. So to prove to ppl who SWEAR that that would put Miami under water I made a pathetic little diagram, pls laugh at it and me as much as you would like. Its just to show that 10'' isnt that much. I used MS paint, and it looks like a 3 year old did it, but who gives a ****. That dotted line is 10'' that person is 5' and they are standing on your average beach.
