Ice extends in the Arctic this year

TUCSON, AZ (Tucson News Now) -

The latest article published by Nature Geoscience shows that the Arctic sea ice is far more at risk to seasonal temperature changes than previously thought. This year the changes happen to mean more ice than in the previous few years.

The 2013 summer happened to be a cool summer in the Arctic region. This cooler summer allowed the Arctic sea ice to expand 41 percent from the year prior. When looking at the years before, the sea ice was about 14 percent less than normal, but those summers were not any cooler than normal.

The image above shows the sea ice was much thicker in 2013 than the years prior.

In 2011, the thickest ice was about 2.5 meters while in 2013, it had a thickness of nearly 4 meters.

The temperature in the Arctic region has gone up in the last few decades and as a result, major ice has been lost every year.

In the last 40 years, the sea ice coverage has decreased by nearly 40 percent.
