2016 Arctic sea ice thread

When will the ice sheet melt?

Obviously, with as much variation as these data display, counting on that exponential trend is a bit of a bet. But it is certainly headed for zero at some point within the next couple of decades at the latest. Now these are summer minimums. This graph will hit zero when the Arctic is first ice free at it's minimum. It is not marking the point where the Arctic will be ice free year-round.[

so again, are you including the Greenland ice in that statement?

Greenland is melting at an accelerating rate, and contributing to sea level rise.

If so, when would you expect that the land ice will melt by? I already asked back a few months or so how long would it take for land ice to completely melt? Or are you saying that the sheet will just slide off the continent at once?

No one knows when the ice sheet will completely melt. So what? Your question is not the significant one. How fast is the ice sheet melting? Is the melt rate increasing? Those are the significant questions. But you are probably much too retarded to understand why.

In the real world....

Between April 2002 and April 2006, GRACE data uncovered ice mass loss in Greenland of 248 ± 36 cubic kilometers per year. The ice mass loss rate increased by 250 percent between April 2002 to April 2004 and May 2004 to April 2006. The increase was due almost completely to increased ice loss rates in southern Greenland (Velicogna and Wahr 2006a). Between 2003 and 2005, the Greenland Ice Sheet lost 101 ± 16 gigatons per year, with a gain of 54 gigatons per year above 2,000, meters and a loss of 155 gigatons per year at lower elevations. The lower elevations showed a large seasonal cycle: mass losses during summer melting, and mass gains from autumn through spring. The ice mass loss observed in this research was a change from the trend of losing 113 ± 17 gigatons per year during the 1990s, but was smaller than some other recent estimates (Luthcke et al. 2006).

In 2010, a study using GRACE and Global Positioning System (GPS) measurements from three long-term sites on bedrock near the ice sheet found that the ice loss already documented over southern Greenland was spreading along the northwestern coast. The acceleration of loss likely started in late 2005. GRACE data gave a direct measure of mass loss averaged over scales of a few hundred kilometers, and the GPS data observed crustal uplift resulting from ice mass loss. Uplift observed by both sources showed rapid ice acceleration in southeast Greenland in late 2003, and a modest deceleration in 2006 (Khan et al. 2010).

As for the sea ice....

Arctic Death Spiral

no the significant one is has any melting caused a rise in sea level.

Yes, it is, in fact, causing a rise in sea levels, moron. When ice that is on top of land melts, and the ice loss is greater than any ice gain from snowfall, sea levels rise. Only retards are unable to comprehend that fact.

well how much evaporation is happening with the seas? Come on man, don't try and pull sht like this. Again, where do you think the calving comes from?

LOLOLOLOL. Do you actually imagine that that gibbering non-sequitur makes any sense whatsoever?

I'm sorry are you saying that glaciers aren't on land? now that's funny. psssst, go with that. yeah that's the ticket.

 

[Crick]

The PIOMAS graphic does NOT include Greenland. It is of sea ice only. If such were the case, it would also have to include northern Canada, the upper third of Alaska, northern Russia, Finland, Sweden and Norway, all of which cross the line.

 

[jc456]

sea ice doesn't add to sea level. you know this right?

 

[Crick]

Yes, jc, I know that.

LOL But I am surprised that you do. LOL

Your bizarre and constant misunderstanding of what other people say to you is the mark of a real true retard, JustCrazy. Do you even understand what 'non-sequitur' means, you poor deranged imbecile?

 

[jc456]

Yes, jc, I know that.

then what's your issue if it melts, it threatens no one.

 

[RollingThunder]

Yes, jc, I know that.

then what's your issue if it melts, it threatens no one.

And the accelerating melting of Greenland? Do you also idiotically believe that that "threatens no one"?

Of course, in reality, even the melting of the Arctic sea ice will have disastrous consequenses for the climate. Too bad you're too stupid and ideologically brainwashed to comprehend that.

 

[LaDexter]

"even the melting of the Arctic sea ice will have disastrous consequenses for the climate"


LMAO!!!

You're joking, hopefully...

BTW, if you think Greenland is melting, you don't know what an "ice core" is, since Greenland manufactures one every year, as it has done for a half million years at least...

 

[Olde Europe]

The above shall be documented as, among valiant competition, the winning candidate for the the dictionary definition of "discombobulated bullshit".

 

[LaDexter]

In other words, you don't understand anything, other than parroting fudge and bull.

An ice core grows each year the above 'tard says its "melting..."

 

[Old Rocks]

Well now, Mr. LaDexter, perhaps you would like to explain how Greenland 'grows' a new ice core every year.

 

[LaDexter]

The above is a confession that Old Rocks has no idea what a GLACIER is or does...

well you nor anyone else has shown Greenland to be melting so, I'm not sure what to say. If nothing is happening out of normal warming and freezing I don't see the problem for anyone other than those on Greenland. Again, ice calving is normal.

 

[Old Rocks]

jc, you have been shown information that scientists from multiple nations have gathered that show that Greenland is losing ice faster than it is gaining it from snowfall. You can scream conspiracy all you like, and wear your little tin hat everywhere you go, that will not change the fact that Greenland is losing ice at an increasing rate.

the last one that was posted was from 2012 bubba. Let's see a current one. BTW, the satellite is down to read the ice, so not sure where the heck you get your ice data. I agree the shores are most likely melting since it is almost July. But you need to show land loss. I'm waiting.

Land Ice


Data from NASA's GRACE satellites show that the land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica has been losing about 134 gigatonnes of ice per year since 2002, while the Greenland ice sheet has been losing an estimated 287 gigatonnes per year. (Source: GRACE satellite data)

so s0n, losing do you mean left the land into the sea? or melted and refroze? be clearer here.

BTW, at -70 degrees F yesterday, do you think the land ice is melting?
