New melt record for Greenland ice sheet (w/ Video)
The figure above shows the standardized melting index anomaly for the period 1979 - 2010.
New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades.
"This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average," said Dr. Marco Tedesco, director of the Cryospheric Processes Laboratory at The City College of New York (CCNY CUNY), who is leading a project studying variables that affect ice sheet melting.
"Melting in 2010 started exceptionally early at the end of April and ended quite late in mid- September."
The study, with different aspects sponsored by World Wildlife Fund (WWF), the National Science Foundation and NASA, examined surface temperature anomalies over the Greenland ice sheet surface, as well as estimates of surface melting from satellite data, ground observations and models.

Melting is a crucial factor in both surface and subglacial processes. Here’s a video showing melting streams, supraglacial lakes and meltwater flowing through ice cracks that we recorded in 2009 and 2010.
In an article published today in Environmental Research Letters, Professor Tedesco and co-authors note that in 2010, summer temperatures up to 3C above the average were combined with reduced snowfall.The capital of Greenland, Nuuk, had the warmest spring and summer since records began in 1873.
Bare ice was exposed earlier than the average and longer than previous years, contributing to the extreme record.
"Bare ice is much darker than snow and absorbs more solar radiation," said Professor Tedesco. "Other ice melting feedback loops that we are examining include the impact of lakes on the glacial surface, of dust and soot deposited over the ice sheet and how surface meltwater affects the flow of the ice toward the ocean."
WWF climate specialist Dr. Martin Sommerkorn said "Sea level rise is expected to top 1 meter by 2100, largely due to melting from ice sheets. And it will not stop there the longer we take to limit greenhouse gas production, the more melting and water level rise will continue."

Look at all the dirt on the surface of the ice. There surely is more to do with reduced albedo caused by the sediments carried by the glacier itself, rather than any generalized atmospheric warming. The ice in some shots there is gray to even black.

This cycle looks almost exactly like the last one in terms of slope, time to, and global temperature at, the next point of inflecton. ( ie, temperature maximum)
If I remember my history correctly, there were no anthropogenic sources of CO2 36000 years ago-except for exhalation of course.
You can see these cyclical phenomena by checking out the National Geographic issue published last summer showing the last 5 million years of ocean depth, which of course correlate directly to global temperature.

That is correct, 2 of the past 5 years are going to show a decrease in sea level. 2010 could likely show a significant drop global sea level. By significant I mean it is possible that it will likely drop between 2-3 mm from 2009.

The article claims a 1000mm rise will occur in the next 89 years ... which is 11mm a year.
When the sea level DROPS by 3.5mm it is significant.
It means for 2010 they are now 14.5mm behind the pace they need for their prediction to come true.

You don't seem to understand what statistically significant means. The global temp for 1998 by itself is not statistically significant, the rate of temperature increase from 1980-1998 is statistically significant because there is a large enough sample size to discover a trend that will have merit in prediction.
A single year's sealevel drop is not significant because it could readily be offset by any number of preceeding or proceeding years.

Nope. I said they only rose 1.8mm in 4 years.
I picked those 4 dates by looking at the last publish value and then went back to the same time in the year in 2006.
.45mm a year is a long, long way from the 11mm a year rise necessary to get 1m of rise by 2100.
And it is about 1/4th of the longe term average rise ... the rise that has been going on for 20,000 years.

So assuming there's no change in mass balance of glaciers or atmospheric H2O average content over that time period you're looking at a low end estimate of 189mm. But, mass balance is still being explored and is very variable based on regional conditions. 880mm is a possibility, worst case scenario only.

Some people say stupid things, that's why science is based on research paperwork and not commentary on the news, magazines, or blogs. That stance and comment are absent from the linked research paper. Now the linked research paper states that over 1 meter would be a high possibility, and makes references to other research, none of which say unequivocally that 1 meter will happen.
