Waves of Destruction...

We've known for some time that warming temperatures pose a big threat to Arctic ocean ice. However, only now are we learning about so-called “waves of destruction” that are speeding up the disappearance of sea ice.

According to a recent article by Mark Harris in Scientific American, the loss of sea ice in the Arctic has allowed large waves to develop in the now-open water. Those waves then break up the remaining sea ice, thus creating a feedback loop that could spell disaster for the ice caps.

Back in 2010, a Norwegian research vessel called the RV Lance set out to study ice pack, as they did every season. Although in previous years the team was able to walk out on to the ice pack, and even camp on larger floes, the 2010 team found too many cracks in the ice to explore safely.

After moving their ship deeper into the ice pack, the scientists noticed how small waves were quickly growing in size and breaking up large pieces of ice. That team recorded some waves that were more than 30 feet high, and watched as they rapidly broke the ice into thousands of smaller pieces.

The whole process is so fast and powerful that areas of over 16 kilometers of ice were destroyed in one hour. And, because of their ability to begin quickly and rapidly increase in power, these waves are nearly impossible to predict.

In addition to destroying sea ice, the waves are also very dangerous to ships, oil-drilling platforms, and arctic communities. This is what happens when a feedback loop is created, and this is how a small rise in temperatures quickly becomes a global catastrophe.

If we don't work harder to restore our environment, we may not survive as a species. We only have one planet to call home, so let's get busy making sure we can survive here in the future. Check out GreenWorldRising.org for more information.
