Greenland ice melts most in half-century: US

Jun 28, 2011
Ice Fjord of Ilulissat in Greenland is pictured in 2009. Greenland's ice sheet melted the most it has in over a half century last year, US government scientists said, in one of a series of "unmistakable" signs of climate change.

Greenland's ice sheet melted the most it has in over a half century last year, US government scientists said Tuesday in one of a series of "unmistakable" signs of climate change.

"The world continues to warm," the said in a briefing paper for reporters.

"Multiple indicators, same bottom-line conclusion: consistent and unmistakable signal from the top of the atmosphere to the bottom of the oceans."

An annual climate survey, which includes work by scientists from 45 countries, said that ice sheet in Greenland melted at its highest rate since at least 1958, when similar data first became available.

shrank to its third smallest area on record, while the world's shrank for the 20th straight year, the study said.

In line with previous studies, the survey said that 2010 was also one of the hottest years on record.

Last year was either tied for the hottest or the second hottest on record, depending on methodology. But all methodologies used showed the temperature to be at least 0.9 (0.5 Celsius) above the average recorded in the three decades through 1990.

The survey noted that 2010 was exceptional for its extreme events, including a deadly heat wave in Russia, floods in Pakistan that displaced more than 20 million people and record snowfall in several US cities.

A series of studies have voiced alarm at the rapid pace of melting in the , which could lead to a rise in sea levels that threatens low-lying coastal areas and islands.

The Oslo-based Arctic Monitoring and Assessment Program said in May that warming in the Arctic was on track to lift sea levels by up to 5.3 feet (1.6 meters) by 2100, a far steeper jump than predicted a few years ago.

Many environmentalists have been disappointed at the pace of diplomacy to fight , with few expecting a major agreement at the next major UN-led talks opening in South Africa in late November.

Former US vice president Al Gore recently accused President Barack Obama of failing to show leadership on climate change, saying that poor coverage of the media had given credibility to skeptics of global warming.

So it melted more in the 1950's , but that was natural. So doesnt the null hypothesis imply that this couldnt be CAGW? Its not unprecedented, its just part of the normal cycle. So sick of climate 'post normal science' being presented as science, its just guesstimation with delusions of grandeur. And always, always wrong.

...and we're so sick of know-nothing shills like you, who contradict yourselves from post to post, and try to end-run around the mass of evidence PRO by cherrypicking crank/wank industry-sponsored propaganda from discredited/fringe "scientists" like Christy, Wegman, et al.

You stepped on your own dick when you claimed that NOAA data show 2010 to have not been tied as the hottest on record with 2005 in today's other climate article, and then come here to comment on this article, while glibly avoiding any reference to the fact that it references the very same fact, as recorded by NOAA- thereby validating the other article.

This isn't the FUXNews channel, and nor are most of us here devotees of the same, so don't expect to be able to peddle your Big Lies here to universal acclamation.

"So it melted more in the 1950's" - Desparate

No Tard boy. Read the entire sentence.. it continues "since similar records became available."

In other words it melted more last year than at any time in at any time in recorded human history.

"And always, always wrong." - Desparate

Cause Tard Boy Says so.

"...failing to show leadership on climate change..."
"...to fight climate change..."

If climate is a big bully, then no punch we throw first is going to thwart the bully's first swing - bullies don't pull punches.

This is going to be the slowest 'quick fix' (assuming any) humanity will ever know.

Next time, if any, we will find someone our size to mess with.

If you ask anyone in any branch of the myriad of geo-science fields where they would choose to live the rest of their lives if they had a 500 year life span and could only choose one place, I guarantee nobody would pick a coastal location .....and 90% would pick somewhere pretty far from the equator....but only if they had to answer the question honestly.

Unfortunately, Arctic sea ice melt will not add to global sea level. Landed ice melting is the only thing that will.

Not by a factor equivalent to its entire volume, true. But still by an a appreciable amount, and that is also in excess of the portion of arctic ice melting that derives from non-floating ice and partially supported ice. Ice in general, and sea-ice in particular are not in a 1-to-1 volume displacement ratio.

This shouldn't even have to be pointed out to you.
