Global warming is a major concern for each and every continent present in this worlds mainly areas covered with ice. Day by day ice is melting and the sea level is increasing. A day will come when this will reach its extreme point and at that time the verdict of 2012 world coming to an end might come true. So on July 8 data the data provided made clear that around 40% of the massive ice sheet covering Greenland was at a point of thawing at or near the surface.
And by July 12, that amount had risen to 97%. Given above are some images by which you can figure out the difference, the images colored with light pink are thae one classified as “probably melt” while areas in dark pink are simply classified as “melt.”
These images are provided by NASA, showing that the melted area is the greatest it has ever been in the 30-year history of satellite observations. This doesn’t lead to any specific conclusions about global warming or climate change, or to the cause of why this massive ice sheet is melting, but the images don’t lie and this is clearly an issue. This kind of ice melt has historically only occurred once every 150 years on average.
“The Greenland ice sheet is a vast area with a varied history of change. This event, combined with other natural but uncommon phenomena, such as the large calving event last week on Petermann Glacier, are part of a complex story. Satellite observations are helping us understand how events like these may relate to one another as well as to the broader climate system,” said NASA cryosphere program manager Tom Wagner.
