"Rates of sea level rise are increasing three-to-four times faster along portions of the U.S. Atlantic Coast than globally, according to a new U.S. Geological Survey report. Since about 1990, sea-level rise in the 600-mile stretch of coastal zone from Cape Hatteras, N.C. to north of Boston, Mass. has increased 2 - 3.7 millimeters per year; the global increase over the same period was 0.6 – 1.0 millimeter per year.
Though global sea level has been projected to rise roughly two-to-three feet or more by the end of the 21st century, it will not climb at the same rate at every location. Differences in land movements, strength of ocean currents, water temperatures, and salinity can cause regional and local highs and lows in sea level.
Cities in the hotspot, like Norfolk, New York, and Boston already experience damaging floods during relatively low intensity storms. Ongoing accelerated sea level rise in the hotspot will make coastal cities and surrounding areas increasingly vulnerable to flooding by adding to the height that storm surge and breaking waves reach on the coast."
What will happen to Florida if sea level goes up 2 to 3 feet? Isn't most of Florida barely above sea level?
We can build dykes and floodgates here in the Northeast to ward off the rising waters and restore wetlands , but Florida really has no options. Most Coastal towns in the Northeast are 3-15 feet above sea level so they will be fine. NYC needs a higher floodwalll and gate system but it will be fine....same with Boston...but the Gulf Coast is worrysome.
Yeah, the sea will have to raise to cover the feet of the Statue of Liberty before conservatives will stop believing that global warming is nothing but a big hoax.
You will have to wait several millions of years for that to happen, if it happens at all.
The OMG Arctice Melt mean the snow got a little slushy. When Ice is floating on water and gets to melt the water level doesn't change because the weight of the water in the ice is the same....
That is true for sea ice, but it doesn't work that way with continental glaciers, mountain glaciers and glaciers on islands which are rapidly disappearing. All that water has to go somewhere.

Projections for sea level rise in coming decades could be too conservative, experts warned Wednesday, saying they found that the rise over the last two decades is much more than predicted by the U.N. scientific body tracking climate signals.
It's in an upward Trend right now slightly above the overall trend. If you llok at other maps:
Quote:
Linear mean sea level trends were calculated in overlapping 50-year increments for stations with sufficient historical data. The variability of each 50-year trend, with 95% confidence interval, is plotted against the mid-year of each 50-year period. The solid horizontal line represents the linear mean sea level trend using the entire period of record.
Evidence means nothing to non-scientific folks. Until climate change deniers can explain how adding more heat trapping gases to the atmosphere does not equate to more heat being trapped in the atmosphere, they are wrong and will always be wrong.
As I pointed out in the other thread this is like asking why would the insulation in my attic not trap heat without knowing if the windows are open. CO2 is only variable of many in climate.
Global temperature increasing and sea levels rising. Did you even read the article?
You can check any chart on the NOAA site you want, what you'll find is this. Most of the stations indicate a rise in the sea level but some actually show it going down. Land movement plays a factor here for land based measurements.
The bottom line is this though, no matter which chart you look at there is going to be a steady and predictable rate whether it's going up or down such as the chart from Key West I posted above. Some of that data goes back to the mid 1800's.

This isn't something that has just started to happen and the rates of rise go through cycles, most are in upward trend right now but that is not something new either. The Battery in NY has one the longest records:
It's important to understand what the following chart represents becsue when I have posted this before some people have misinterpreted the flat line as meaning it hasn't risen. The one above shows the actual readings which indicate a slow a nd predictable rise, this one shows variations over the last 150 years the rate of rise has risen or fallen:
That is true for sea ice, but it doesn't work that way with continental glaciers, mountain glaciers and glaciers on islands which are rapidly disappearing. All that water has to go somewhere.

That isn't Climate Change™, it is a process of sublimation and has already been established as such. In fact, Gore (I don't care about gore, but this claim was his flagship for a while) and those who attempted to use it as support had a lot of backlash for it.
Here is the paper that showed what is responsible for the melt with Mt. Kilimanjaro.

Yes, and on top of all that doom and gloom, the sky is falling!!!! Yikes.
A couple simple questions for you to attempt to answer honestly.
Over the period from 50,000 BC to 1 AD, what happened to the overall climate (changed, stayed the same, had Ice Age(s)), and what cause any of what you cite as having happened.
