The Day After Tomorrow?

You probably remember the movie 'The Day After Tomorrow' and the fact that how climate change can lead to a disaster. Apart from the huge exaggerations which made the movie quite exciting, it was still based on some proven scientific facts. A shaft in the major ice shelves within either of the polar regions or melting the ice shelves, will result in a total climate change all over the world which all stem from a minor increase in atmosphere temperature or what we call "Global Warming".
Interestingly new studies have shown that is actually beginning to happen. Here is the link to the BBC news.

To make it short, these are the highlights which would interest you.

  1. Scientists say data from satellites and weather stations indicate a warming of about 0.6C over the last 50 years.
  2. The continent of Antarctica is warming up in step with the rest of the world, according to a new analysis.
  3. Meanwhile, scientists in Antarctica say a major ice shelf is about to break away from the continent.
  4. The Wilkins Ice Shelf is said to be "hanging by a thread" from the Antarctic Peninsula, the strip of land pointing from the white continent towards the southern tip of South America.
  5. A BAS team currently on site is reporting that the Wilkins shelf, about 15,000 sq km in area, is probably about to break free.
  6. "It really could go at any minute, and I wouldn't be at all surprised if the final cracks started to appear very soon," said BAS's David Vaughan.
  7. Last year, scientists from the UK Met Office used climate models to attribute trends at the poles, and concluded that human emissions of greenhouse gases were largely responsible for the observed warming.
  8. A much bigger question is whether the new analysis of Antarctic warming heralds any major melting in the West Antarctic ice sheet, which could lead to big changes in sea level and global impacts.
