It has come to the knowledge of climate scientists that the ice sheets in Greenland are melting at a record pace.

Greenland’s ice sheets have begun the summer meltdown and things are not looking good so far. The climate scientists are worried sick and they cannot make heads or tails out of it.

The figures they thought were final have been trumped. Now they have had to correct the results before releasing them for public perusal. Almost 12% of the ice sheet regions of Greenland were melting very fast this time around. It is not a good sign.

That is nearly 656,000 square miles of territory that is floating out to sea. The process has begun earlier than usual. This has sent the scientists running back to their trusty models and trying to tweak them here and there to closely match reality which is always two steps ahead.

The meltdown is a definite fact and not just a symptom of doom-mongering. As for the rising sea levels, they will wreak havoc on the coastal areas of the global village.

While the total amount of ice that is melting isn’t that much, it has had a head-start this time around. This spells trouble since the effect is cumulative.

The process of melting and refreezing can lead to a heat imbalance which further affects the climate in deleterious ways. This phenomenon could lead to a repetition of the situation in 2012, according to Denmark's polar research site, Polar Portal (via CNN).

That was when over 95% of the ice sheet saw some melting. Greenland’s ice sheet is about the size of Alaska. It is the second biggest contributing factor in melt-water on a global level.

Only Antarctica is a more potent source. Ice is being lost at a rate of 287 billion metric tons annually from this region. If the entire ice sheet were to melt, it would lead to sea levels rising by 20 feet.

The changes in weather conditions could be dramatic thanks to this state of affairs. Temperatures are shooting up throughout the world due to the overall upset balance of natural forces.

Even in the Arctic, is getting warmer and warmer with the passage of time. Sea levels will surely rise by 3 feet by the end of the 21st century. This is a climatic hazard in its own right. To avert this disaster requires emergency steps which can only be accomplished piecemeal.
