This has been a sensationally hot summer for America, with records breaking daily. But Greenland seems to have just claimed the heat-related phenomenon crown, with 97 percent of its ice sheet turning to slush. The even stranger part? It might be completely normal--at least for now.
The melting isn't a one-off event; every summer Greenland's ice melts some amount. But it's usually about half, and in the 30 years we've been keeping a satellite eye on the changes, we haven't seen anything like this. It was so out of the ordinary, in fact, that scientists from NASA's Jet Propulsion Laboratory questioned if it was caused by some kind of malfunction. The melt had to be confirmed independently by other climatologists.
By July 8, according to the satellite information, 40 percent was melted. Four days later it was up to 97 percent, and even the area around the highest point of the ice sheet, Summit Station, showed signs of melting. At the same time, a ridge of warm air known as a heat dome was affecting the country, which likely had a lot to do with the melting.
We know from analysis of ice cores that the last time melting like this happened was circa 1889, which, you'd logically think, would mean this was completely unexpected. But it wasn't. Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data, said in a statement: "Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time."
Researchers don't know yet if this will contribute to sea levels rising in Greenland, but if it happens again in the next few years, that could threaten the stability of the ice sheet, which would mean major cause for concern.
Yeah, we're screwed.
@Aldron, explain this away.
that ish is crazy!!! well hopefully the pattern is correct, but if not then yeah, we are in for some water rising, resource lacking, every man for himself type of life :). Dont worry, the only thing guaranteed in life is death anyways..
Taxes, you forgot taxes!
Eeek, the virus that killed the wicked which of the west is spreading! WE ARE ALL MELTING! "...oh, what a cruel, cruel world...."!
It's just the surface ice ... not the entire ice sheet. The sheet is 2 miles thick at some points. They mean that a thin layer (millimeters?) on the surface of the whole sheet showed signs of melting. Normally only half of this thin layer melts each summer.
D13, you seem to forget that climate works in cycles. Things like this happen naturally. Climate change won't make things all hot all the time. Only change the frequency at which these 'freak events' happen.
Greenland isn't a country. It is a part of Denmark :O
unfortunetly there are much worse thangs that can happen then flooding if two much fresh water gets into the ocean. first of all the fresh water is always melting and going into the ocean wich brings oxygen to the all of the creatures in the ocean becuse the fresh water and salt water are not the same consitancy wich creates underwater currents that deliver oxygen to all the creates of the sea much like a bubbler gives oxygen to the fish in your aquarium wich is a good thang the problem is if two much fresh water gets into the ocean it is posible the water would begin to mix would most likely slowly stop providing oxygen to the creatures of the sea. i beleave that if this happens even on a small scale it would truley be awfull.. many of the countrys in asia have a deit that is mainly sea food wich means if there food supply starts to dwindle they will begin eating other thangs wich would drive up food prices dramaticly wich could lead to mass starvation, oh but it dont end there no that would be to easy if the creatures of the ocean start to decay on a large scale it is posible the deadly gases from there decomasition could lead to postionous gases to be realeased from the ocean and poison many coastal regions and even posibly get into the clouds and produce awfull acidic rains that would be horrible,,, this is an awfull posiblity that i truly hope never comes to pass
As a well spent day brings happy sleep, so life well used brings happy death.
While the melting ice is significant, I don't believe their is a government conspiracy to hide the truth about global warming. The truth is our planet's weather changes on a scale much larger than decades. We've only been recording weather with satellites and advanced technology for the past 70 years or so. So how can we judge what is normal and what isn't for a 150 year time period?
D13 is fear mongering on a subject he can only speculate about. The facts are: This has happened in the past and its consistent with the data collected. Not once in your elaborate explanation did you cite factual evidence of a larger problem. Yes climate is changing, yes it will affect weather/crops and such. But to exclaim their's a big government cover up every time something happens gets annoying.
The science community has clearly displayed redundantly, the cycles of ice melting on Earth is sync with the suns rays. Science has also show, the we humans have excellrated the process with with global carbon gases. Additonally, we humans are just pollution the Earth as well and killing of life every where.
I fear, one year 7 billion or more in the future, will be reduce to 1% world poppulation and those living will just be getting by barely....
GOD BLESS ALL! If I must die, I want to live and die as a Christian. Praise God always and show this by to GOD, by loving and caring to others always! Take care. ;)
The only people still wasting time arguing about climate change on the internet are part of the problem. Not because you're right or wrong, but because whether you're right or wrong, it's only by accident.
The day I go see anybody other than a doctor for my medical problems, slap me. The day I believe any schmuck's ramblings about climate change on the internet, journalists included, slap me.
Let's hope it all melts because I want to take advantage and buy new ocean front property -- on what's left of Florida anyway as most will be under the sea.
IF this is true - look at the dates. It only took 4 days to go from a little melting to almost all of it melting. NOT posible.
Have any of you believers even been around snow and ice?
At the 3M main headquaters here, they pile up the snow plowed off their parking lot into a HUGH pile of snow. Of course it will turn to ice as the temps warm. This ice gets covered with dirt from the parking lot as the layers get added to the pile from each time it snows enough to plow, as well as just from wind blowing more on top of it. That ice pile under that dirt and stuff can last into June, even with temps in Aril and May into the 80s and higher!!!!
So that fact that a HUGH area of snow melted in that short of time is not possible and if it is would mean a VERY HIGH temp increase, not possible in Greenland.
lol climate wackos are all going "we told you so". XD
Solar activity has peaked this year, just as it was expected to, and Lord behold things got hotter. Who do these climate 'scientists' think they are fooling?
But then again, when things get 10 degrees colder they will still cry wolf. =.=
Mmm, as the sun peaks later in 2013, does this just mean more slushies later too, combined with human carbon enhancing gases....
Warm ocean currents likely have more to do with Greenland's ice coverage than atmospheric temperatures. As for Greenland's ice melting causing sea levels to rise, why would it only occur near Greenland? And wouldn't the greatly reduced ice mass over the Greenland continent cause a slight rise in the land surface?
