The glaciers in Greenland cover an area of over a million square kilometers with an average thickness of about 2 kilometers, and make up a significant percentage of the fresh water in the world, the water you added to the oceans would raise the level by about 6 meters
Some time ago I saw how a commenter "Yaden" tries to repel the accepted assumption that global warming is a result of human activity - greenhouse gas emissions - by bringing news that "what causes the melting of the glaciers in Greenland is the heat of underground volcanoes", is that right?
Before we continue, clarifications: our globe has been in an ice age for about 35 million years, this was first due to the establishment of the Antarctic continent at the South Pole and then the closing of a land circle around the North Pole, a situation that prevents the movement of water to the poles, mixing and dispersal of the cold, resulting in ice until it preserves its environment Happened.
Every period the angle of the poles towards the sun changes - Milankiewicz cycle - a change that gives our globe a warm respite, in the current period we are in the process of changing. The North Pole is "moving away" from the sun, a situation that is supposed to put the northern part of our globe into an ice age, but according to surveys and studies it turns out that human activity / greenhouse gas emissions will delay the process by hundreds of years, that is, an ice age that was supposed to arrive in the first third of the third millennium, will be postponed to its end And perhaps by the beginning of the fourth millennium, this forecast could change if, following global warming, the currents of the oceans (the global conveyor belts - the Gulf Stream and others) stop, since such a stop would lead to a rapid cooling of the northern hemisphere.
Without a direct connection to the Milankiewicz cycle, local events such as the eruption of volcanoes affect and occasionally cause a rapid drop in temperatures in large areas and are attributed to the phenomenon of "little ice ages".
Back in Greenland, observations in the 30s showed that a huge glacier doubled the speed of its "flow" towards the North Sea. The glacier, which moved at a speed of about XNUMX meters per day, turned on warning lights for glacier researchers, lights that flash when the phenomenon recurs throughout the island.
The glaciers in Greenland cover an area of over a million square kilometers with an average thickness of about 2 kilometers, and make up a significant percentage of the fresh water in the world, the water you added to the oceans would raise the level by about 6 meters.
It is worth noting that: The water of the melting glaciers in Greenland and Antarctica was not calculated in the report submitted to the UN in 2007, The 2007 report by the Intergovernmental Panel on Climate Change. This is because of the lack of understanding of the issue.
Fifty years after the fast "sliding" was diagnosed (today), it turns out that the sliding continues, although not at the same speed, the progress of the glaciers towards the sea is being investigated by Gordon Hamilton of the University of Maine Gordon Hamilton - University of Maine. The issue is gaining importance ahead of the global conference on global warming that will be held in Copenhagen in December (2009).
It turns out that the snow that falls on the heads of the glaciers is not enough to fill the lack created by their melting and flow to the sea, although the picture is starting to clear up, not everything is clear yet, it is not clear how many of the changes are caused by natural factors, but the role of man in the process is becoming clearer and clearer, according to David Holland, director of the Center for Scientific Atmosphere and Ocean at New York University, the more accepted explanation today is because what is causing the increased melting and convection of the Greenland glaciers is warm water.
Air and water penetrating cracks in the glaciers are a melting factor, but today researchers think that the main factor in the melting and transportation of the glaciers are currents in the ocean, warm water that comes from the south penetrates in periodic pulses to the bases of the glaciers, melts them and "oils" their gliding paths to the sea.
Measurements showed that in July (2009) the ocean water was the warmest in the last 130 years, it is clear that man has a significant part in the warming and hence also a significant part in the melting of the Greenland glaciers. Recent measurements have shown that there are glaciers that move at a speed of 10 km per year, a speed that would be enough to reach the sea and cause the sea level to rise far above the predictions of the international "panel" in 2007.
No one is ready to predict and say whether the process will take a hundred or a thousand years, but why wait if it can be prevented?

Avner,
If it is nonsense that "the connection between it and real science does not exist", then why do scientists study the subject? Maybe they are also not related to science at all?
It is not about some whimsy, there is almost a scientific consensus. The subject is taught in universities.
I did not check if your claim about Mars is true, but even if it is true it is not relevant at all. According to the logic of this claim, a murder suspect can say "Julius Caesar was also murdered, perhaps you suspect that I murdered him too?". The demagoguery of this claim is to bring a similar case, which is self-evidently impossible to attribute to the suspect's fault, in order to claim that if the similar case is not the suspect's wife, then all the cases are not his fault either.
There is no logic here.
Sorry for the harshness of my response, but your comment that it is "bullshit" deserves such a harsh response.
Global warming = the latest bike apocalypse.
Throughout human history there have been prophets of wrath who were alarmed that the world was coming to an end.
The same goes for global warming.
did you know On Mars, the polar ice caps have also shrunk in recent years. Is the person responsible for this...?
In short, it is nonsense that has no connection with real science at all.
Watch and enjoy

Ron,
I went to the ice age now website, from which you get most of your information. I have been patiently searching for scientific articles (that is, ones that have been peer-reviewed and published in a scientific journal) that support the view you presented. I did not find.
What I did find is a note that according to the known cycle of the ice ages, an ice age should start around now. The known data (in scientific journals and universities) actually indicate a depreciation of the glaciers - so the conclusion is that despite the fact that there *should* be an ice age now, the warming is so severe that the glaciers are melting despite this. That is, if we were not in a cold period, it would be much warmer.
I discussed this with you before and you claimed that the reason for the global warming claims is that greedy scientists want to get money to fund their research (or something like that, don't take my word for it).
Why wouldn't those scientists take money from the people of the fossil fuel industry, who would certainly be happy to fund research that opposes the warming hypothesis?
Why does the research about warming get wall-to-wall support, while the opposing studies are published on esoteric sites? Are only these sites honest and the rest misled by the conspiracy, or worse, colluding? Do you want me to look for journals that have published articles supporting the global warming thesis, so you can declare them one by one unprofessional or frauds?
To Ron
Blackmail on the dig.
Whether we cause warming or not it doesn't matter our pollution has a very negative effect on the environment and on us even without global warming and dependence on minerals and especially oil has a negative effect on international society, the bottom line is that we must stop polluting and everyone must do it at the private level and at the national level we must Switch to electric vehicles, and especially the state of Israel, which is home to companies such as Ormat and Solel, which can build geothermal and thermo-solar power plants instead of the old, polluting power plants and is a leader in global cleantech, should do this.
You all know the graph that shows that this is the hottest period in the last 1000 years based on Tree ring reconstruction

This is the backbone of the "warming scientists".
Real and honest scientists have asked countless times for the data that created this graph - but have been denied.
But we finally have the original data for the graph: and it turns out that the warming scientists decided to cherry pick specific data
And not to enter all the data, why? Because the graph becomes like this (see the black line):
tinyurl.com/TheAuthenticGraph
Here is the whole article tinyurl.com/GraphFullPicture
And the data in the field fit like a glove for the expected climate
The air is getting colder
But the sea is warming - this happened in every ice age - because where does all the moisture that turns into snow come from, if not from the sea?
The earth enters its natural circle -
The beginning of Ido Korach
-About every 11500 years - the great ice ages started and ended
-Approximately every 179 years - it is colder on Earth due to the position of the planets in front of the Sun and the magnetic field
- About every 360 years - there is a mini ice age
-Approximately every 1440 years - the Earth is in a colder state
We are now at a time when all 4 cycles intersect in our time, meaning that now all four are being fulfilled together.

With that, due to human activity, most of the glaciers in the world are supposed to be shrinking - enough with this percolating lie - enough!
90 percent of glaciers grow worldwide

Light, the warming will lead to the melting of the glacier (Greenland and others) which, as mentioned, will release a lot of fresh water into the ocean, the fresh water is heavier than salt water, the fresh water will cause the conveyor belt to slow down (the golf conveyor belt) which will stop bringing heat to the north and cold to the equator, which will cause an ice age that will spread over the entire globe Country.
Of course, this is just one theory, it is possible that we (humans) will continue to release gases into the atmosphere and cause a tremendous heat that will overcome the cold and eventually our planet will be hot and dry (or not dry, but hot), some say that Venus is global warming out of control.
What is it, sweat a little? In 2006, 3000 people died in France from heat stroke.
Don't be afraid of what you don't understand.
What is the likelihood of the large conveyors stopping? How can such an event be predicted? Will the warming first lead to the conveyors stopping and cooling down or just warming up?
warming up?
So they will sweat a little.
