Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet - - 61 centimeters - - higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences.
The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports.
"It's a big deal" because the projected sea level rise is a conservative estimate and it is likely to be higher, said lead author Steve Nerem of the University of Colorado.
Global sea levels were stable for about 3,000 years until the 20th century when they rose and then accelerated due to global warming caused by the burning of coal, oil and natural gas, said climate scientist Stefan Rahmstorf of the Potsdam Institute in Germany, who wasn't part of the study.

I thought Obama stopped that.
Here’s something I always think regarding climate change-
Let’s suppose we, as a species, decided we wanted to cool the entire planet.
How would we go about that?
I mean, we’re heating it up without even trying, correct?
So, since we’re so powerful what would we do to lower the Earth’s global temperature?
Could we?
We could have a nice thermonuclear war to set up several years of false winter, right?
No, that wouldn’t ‘save’ us.
Besides killing a few billion people, which I hear would do the Earth a bit of good, we’d still want to have food and breathe fresh air.
If we built giant factories whose sole purpose was to spray gasses into the atmosphere would that do it? How long would it take?
Other than give someone all our wealth and control over every aspect of our lives because they swear they might be able to save us, what are we supposed to do?
total lies.
antarctic ice has reached record levels:

so what if the rise in sea level is not from rising temps, but from changes in the surface of the sea floor. as if the earth suddenly got a big pimple. who are they going to tax then?
Put an ice cube in a glass of water and mark the level of the water with a Sharpie.
Wait for the ice cube to melt.
After the ice cube melts, not that the water level is still at the Sharpie mark.
WHAT WE LEARNED: Floating ice does not raise sea level when it melts.
“Global sea levels were stable for about 3,000 years until the 20th century”
It begs the question - why is there an ancient Cyprus grove under 60 feet of water off the coast of Alabama?

IOW - at what level are the oceans SUPPOSED to be?
That’s why they’re whinging about Greenland and other land-based ice sheets.
Based on the article a few weeks ago about all the artifacts being discovered as glaciers in Norway receded, at this rate we might see ice coverage dwindle back to where it was before humanity really got going.
Oh, wait...
So wouldn’t that imply that increased human activity *increased* ice sheet coverage, and maybe all of our “climate change” efforts are actually the culprit behind all those shrinking glaciers?
Fight Climate Change! Justice for Doggerland!
The claim is that continental and valley glaciers will melt and spread land locked ice to the ocean as liquid water...
Not that I agree, but that is the argument.
The oceans cover 70% of the Earth’s surface. Land 30%. It takes a lot of ice melt to affect the depth of the oceans. Ice has a larger volume, and lighter weight, than the water that it is made up from. Snow has an even larger volume. This volume varies greatly, as snow is packed densely or lightly.
Is there a freeper who can calculate the volume of ice/snow that would be required to melt to raise the oceans 1 inch? Private mail and/or public posting.
Why is flood insurance being sold in Florida? Need to evacuate the entire peninsula. RIGHT NOW!
Unless, of course the years leading up to the end of the century constitute the beginning years of the next 200 year mini-ice age, the last one of which was just thawing out around the time of Washington’s crossing of the Delaware (the completely iced over Delaware River, which was breaking up into huge ice chunks during/after the crossing in 1777).
In which case the “melted” ice caps will be seen to be being re-frozen into new ice caps... in the normal solar cycling of climate and the movement of our poles on the axis.
Somebody better tell Al Gore that his California seaside mansion is about to get wet.
I got tired of ice cubes melting and overflowing my glass. So I stopped using ice cubes.
