I'm not denying climate change is occurring but I wish that people would stop with all the doomsday Chicken Little "The Sky is Falling!" tactics. "Could" is doing a lot of work in that headline. It is incredibly unlikely that all of the ice in the Arctic Ocean will completely melt in 17 years.
The Earth is one of the most complicated systems in existence, it is arrogant and naive to think that we can effectively model its climate and make accurate predictions. We don't have the understanding or the computing power to input all of the necessary variables.
