Fears at melting Arctic ice:

Experts are worried that ice in the Arctic is getting thinner, making it easier for it to melt. Although the area of ice looks as big as it did last year, satellite information gathered by NASA shows it’s thinner than it used to be. It’s thought the amount of thick ice formed in the area thousands of years ago has reached an all time low.

And some scientists are worried that in years to come there may be no ice left there at all. Most forecasts suggest that all the ice in the Arctic will have melted away by 2050, but one report said it could be gone by as early as 2013.
