Ever Heard of "Arctic Cyclones"?

“Arctic cyclones” are, obviously, cyclones that occur in the Arctic regions. It is parallel to the Pacific “typhoons” and the Atlantic “hurricanes”.

Recent news that I read in http://esciencenews.com/articles/2013/12/11/arctic.cyclones.more.common.previously.thought tells of an increase in identified cyclones in the Arctic, that these cyclones are actually more common than what is previously thought. Although this does not imply that the actual number of cyclones in the Arctic has drastically increased in the recent years as compared to what it might have been hundreds or thousands of years ago, it still certainly deserves global attention.

There is considerable information about Arctic cyclones and there is constant monitoring of the ice levels in the Arctic, but much research still has to be done to connect the dots and know which causes which and to what extent they do. Probably this phenomenon is still a little overlooked by most because it is spatially distant to most countries, but the implications of changes in the patterns in the Arctic will surely affect global climate.

It might be helpful to share some information with their corresponding contexts: http://nsidc.org/arcticseaicenews/.

The thing about Arctic cyclones is that, it does to the ocean waters the opposite of what a tropical cyclone does. While a tropical cyclone pulls colder water from deep towards the warmer surface, an Arctic cyclone pulls warmer water towards the colder surface. The cooling of the ocean in the tropical regions as result of a tropical cyclone might be harmless, but the warming of the ocean in the Arctic regions brings about the melting of ice, which obviously cannot be good for, well, the world.

I think that this is not just a concern of the countries near the Arctic. We know that all have an impact on the global climate and all are affected by it. The oceans are connected, and a rise in the sea waters can be really dangerous for low-lying island countries. How will the international community react? More research has to be done, and action should result from the findings.
