Per NASA's Study Posted Yesterday, Arctic Ice Recovery May No Longer Be Possible - Independent

Winter sea ice in the Arctic has failed to reform fully for the third year in a row. Scientists said yesterday that the area of ocean covered by Arctic ice at the end of the winter months was lower only in March 2006.

Researchers fear that the floating sea ice is now on a downward spiral of shrinkage that cannot recover fully even during winter because of warmer temperatures. Walt Meier of the US National Snow and Ice Data Centre in Boulder, Colorado, which released the satellite data yesterday, said: "We're seeing near-record lows and higher-than-normal temperatures. We expect the downward trend to continue in future years."

The maximum area of the northern hemisphere covered by sea ice in March 2007 was 5.7 million square miles, compared to the 5.6 million square miles recorded in March 2006. The long-term average for March sea ice, as determined by Nasa measurements from 1979 to 2000, is 6.1 million square miles, according to the centre.

Sea ice in the Arctic oscillates naturally during the seasons, with the area of ocean covered by ice shrinking to its peak minimum extent during September and expanding to its annual maximum during March. Since 1979, when satellite measurements began, summer sea ice had declined significantly. In September 2005 it reached an all-time record low, with September 2006 the second-lowest. Scientists fear that the winter failure of the ice to recover fully will mean there is less ice to start with at the beginning of the summer melting period, leading to more rapid shrinkage with each subsequent year.

1. Wait, wait, don't tell me...

This means that the Arctic will be ice-free faster than expected. Did I win?

2. Yes you win but there are many losers

The Artic will someday recover its ice but not while we're around
