Scientists are saying that some of the scenarios regarding future Antarctic meltdown are downright unrealistic.

How the southern polar region will transpire in its state if global warming rates go sky high is one of the most difficult questions to answer. What we do know is that the waters at the shores will rise by 10 cm by the time the next century begins.

However, the alarmist viewpoint that the rise in water will be 30 cm or more has a one in twenty chance, according to a new study published in the journal Nature. This makes it a highly unlikely scenario. 

The latest work regarding the water rising within a century’s span has a lot of effort behind it. Physics played a central role in the information generated about bedrock mechanics and ice floes and how they react in combination with temperature changes.

Also satellites which are stationed in orbit around the earth give valuable clues as to how the Antarctic Continent is going to fare a 100 years from now. The Amundsen Sea towards the western side of Antarctica is losing its frozen state at a fast rate. The glaciers present here are in meltdown mode and this trend cannot be reversed. 

Some 3000 computer simulations have been done and these models lend vital clues as to how the future will play itself out. By comparing the simulations with the current reality, the overall trends could be predicted. And although this is an inexact science, it will do for now. The results speak for themselves.

The maximum the sea levels will rise is by 10 cm. But to speak of floods and deluge is just plain nonsense. Such extreme weather conditions will not be happening at all. Parts of Antarctica are just too stable to be slipping away in a liquid state into the seas. And this is a fact that you just cannot deny. 

However, to once again speak the truth, such a doomsday scenario may happen over hundreds or thousands of years. There it looks very real in its scope. Within the next hundred years however such an extreme prediction does not hold water (no pun intended).

By the start of the next century mankind will have progressed so much that we will probably have found a solution to global warming. Our polluting ways will have gone the way of the dinosaurs.

So although global warming is something to worry about, it is not that we will all be inundated with water within a hundred years. This is not the way the world works for the earth keeps its homeostasis.
