When the world is gripped by the winter chill and the snow is falling, it’s easy to forget that it’s not quite as cold as it once was.
The Earth is no longer at its maximum temperature.
Instead, temperatures have dropped by about 4 degrees Celsius.
But that’s not the end of the story.
The warming of the Arctic has also accelerated the melting of the Greenland ice sheet, which has begun to recede.
It is also affecting the melting trends of the Antarctic ice sheet.
The Greenland ice shelf is melting faster than the Antarctic.
And the ice sheets of Antarctica and Greenland have both begun to collapse.
If the glaciers in the Antarctic and Greenland melt, the ice shelves of the continents will continue to expand, says lead author Steven van Zandt, an oceanographer at the University of California, Irvine.
“It’s an irreversible process,” van Zander says.
The melting of Greenland and Antarctica has been a major factor in the rise of sea levels and in the rate at which coastal cities rise.
“That is one of the most worrying trends,” van Sadelhuis says.
“But this is also the fastest-moving climate system in history.”
The Greenland melt The Greenland is a relatively new and very large land mass, and the melt is occurring in a relatively small area.
The melt is happening in the waters off the coast of Norway and the Barents Sea.
Scientists have estimated that about 5 percent of the ice sheet has melted so far.
But some of that melt has occurred on land.
The icebergs that have fallen in the North Sea have been floating for years.
In 2012, researchers found that the entire surface of the Bering Sea had melted off the eastern tip of Greenland.
The amount of melt has also risen dramatically since then.
The ice is melting in response to a series of factors.
The weather patterns of the past have been altered by climate change.
As Greenland melts, it is getting warmer, and so the sea is warming.
And as the ice is melted, it gets thinner.
So as the Greenland sea ice retreats, it will absorb more and more of the sun’s energy as it melts.
This is what is happening to the ice on the northern tip of Norway, which is the only part of Greenland where the ice has yet melted.
Greenland ice is a thick, thin sheet of ice.
The thin surface melts in the sun, releasing water.
The thick ice absorbs heat from the sun and then slowly expands as it cools.
When the ice melts in Greenland, the water freezes into ice, which can rise to the surface.
That’s how ice sheets have grown in Greenland for a long time.
As the ice retreat, the melt water can cool off and form lakes, which help form the ice caps that rise to form the Antarctic continent.
The loss of ice has been happening for a lot longer than the melting has accelerated, but the ice-sheet dynamics are changing rapidly.
As more and the ice retreated, the oceans warmed and the climate shifted.
This was already happening in recent years, van Zanders explains.
The ocean is getting colder, the Arctic is warming, and more and further away from land is becoming more and farther away from water.
This means that the oceans will warm, the sea ice will melt, and Antarctica will warm more slowly.
The warmer waters around Antarctica are making the ice shelf collapse more rapidly.
Greenland’s ice sheet will collapse, too Greenland is the smallest and smallest ice sheet on Earth, and it has been the most important one in the last century, says Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado.
The rate of melt of the land and ice sheets is now accelerating.
“We are seeing the Greenland and the Antarctic melting at the same time,” Trenberger says.
This may be happening to some extent because the melting happens in a lot more places, Trenner says.
Greenland and Greenland’s glaciers are melting at a rate of about 3 centimeters per year.
Greenland is melting more quickly than it has ever done before.
Greenland has the fastest melting rate in the world.
“There are so many things happening at the Greenland surface,” van Wijk says.
And all these changes happening at once have been happening at a rapid pace, he says.
Trenter says it is not just Greenland, but also Antarctica and the rest of the Southern Hemisphere that is melting at an accelerating rate.
Greenland, he points out, is not the only place where this is happening.
“The Antarctic has been melting at much higher rates for the last several decades,” he says, “and so these areas are not necessarily experiencing this acceleration.”
How will the melt change the planet?
The rapid melting of ice and land in the Southern and Northern Hemispheres is having a direct impact on climate change and on ocean circulation.
“These are changing oceans,” van Rensburg says.
For the oceans, the melting is a natural phenomenon,
