Polar bears won’t have a home: Artic Ocean will be Ice free by 2050

Even if carbon emissions are significantly reduced, the Arctic Ocean is most likely to be devoid of ice during the summers of the year just before 2050, as revealed by new research published by the Geophysical Research Letters in its journal.

The research made use of the latest generation of tons of climate models taken from 21 research institutions worldwide.

Research has indicated that the mean average temperature in the Arctic region is already 2 degrees Celsius short of what it was in the pre-industrial age. Due to such a rise in temperature, the sea ice is disappearing at a fast pace.

This particular study has sent an alarm to scientists, and they have increasingly called for a reduction in the emission of greenhouse gases which would, in the long term determine whether the summer ice in the arctic would be able to recover in the future.

If the greenhouse gases continue to be emitted at record high levels, then there is a huge possibility of the Artic even being devoid of ice during the cold winter months. Scientists have made it clear that this scenario is dangerous.

Alarmingly, the models constantly showed the potential of the Arctic Ocean being ice-free in the summers before the year 2050 irrespective of the kind of stringent measures we will take or put in place to tone down the effects of climate change. Ed Blockley, who is the leader of the U.K Meteorological Office polar climate program and was also one of the team members who conducted the research to reveal this information, told The Guardian.

“The signal is there in all possible features. This was extremely unexpected and is extremely worrying”. Blockley, however, made it known that the models used are not perfect and there is room for error. A lot of certainty still exists, he said. But all models are clear that the sea ice will still continue to decline. When it gets to some point, it will be gone but when that will take place is still uncertain.

Since satellite records started in 1979, the Artic summer ice has lost some 40% of its total area and even up to 70% of its total volume. These figures are often interpreted as the most visible signs that man-made climate change is actually happening.

With the gradual loss of icebergs, scientists have shown that this has led to a gradual exposure of the dark ocean that has the capacity to absorb most of the sun’s heat which has further increased the temperature.

Changes in the climate globally are also being linked to a higher rate of extreme weather which includes destructive hurricanes and even life-threatening heat waves.
