Greenland ice melting at unprecedented rates — rising global sea levels around the world

Leading an international team of researchers, Dr. Luke Trusel, a glaciologist in Rowan’s Department of Geology (School of Earth & Environment), is the lead author of an article published in the journal Nature that demonstrates the mile-thick Greenland ice sheet is melting, running off into the ocean, and contributing to rising global sea levels at rates far greater than normal.

Based largely on the analysis of refrozen melt layers in ice core samples extracted from Greenland, the study shows that Greenland’s melt began increasing at the dawn of the Industrial Revolution, and has greatly accelerated over the last several decades to levels that have not been experienced over at least the last several centuries, if not thousands of years.

Titled “Nonlinear rise in Greenland runoff in response to post-industrial Arctic warming,” the article, which published online Dec. 5 (Dec. 6 print edition), is the first research article led by a Rowan faculty member to be published in Nature.

Trusel said the greatest takeaway from the study is the speed at which Greenland ice is melting, particularly over the last two and a half decades.

“It’s not just increasing, it’s accelerating,” he said. “That’s a key concern for the future.”

Are they still afraid that if the greenland ice melts to fast, it can stop the gulf stream from reaching northern Europe?

@horgen: What would be the rammifications of that?

The article says different than the title of the thread.

Unprecedented implies it has never happened before, while the article states that it hasn't happened in at least centuries.

Interesting, however a one time Nobel laureate and Steven Crowder both have videos explaining how we're 'retarded' for believing in global warming. They aren't paid by donors with an agenda.

Mmmm hmmm...mmmm hmmmm...this all sounds scary and world-threatening and all, but why haven't you said anything about the REAL threat to our society? Immigrants.

It is believed it will lead to colder climate for West and Northern Europe. Perhaps a 5C degree drop or so.

Which has been disputed.

First time I am reading the opposite conclusion on this. Do you have more links to other studies on this?

Circumstances are not nearly as clear in parts of the oceans, particularly in the Gulf Stream circulation. Insufficient data, the high complexity of ocean dynamics, and the resulting deficits in climate models currently do not permit reliable conclusions on the degree of human influence and to predict with high accuracy the future development of the Gulf Stream circulation. The past decades have shown no obvious trend, but rather a surprisingly large natural variability

Come to think of. Where does the heat normally go if not into the atmosphere? That heat has to go somewhere, otherwise the water in that stream will end up boiling, which it obviously doesn't do.

Personally will notice a huge effect if doesn't get released in western and northern Europe.

Extremely depressing. But, buy more fuel efficent cars. do your part.
