The Arctic Ocean could be ice-free in summer months within 20 years. Is this a sign of major problems to come?

  • Yes it is.

    We as a nation and as a world need to stand up and take notice to what mother nature is trying to tell us. Our actions are killing the planet and if we do not act now, we will be too late to do anything to save us, I say.

  • Artic animals will be endangered

    Though the arctic animals like polar bears can swim for a long time it doesn't mean they can swim forever. If the arctic becomes Ice free, then polar bears will have no food to eat and will eventually starve to death. Other animals such as seals who require land (ice) will also end up dying.

  • Yes it is.

    Having such a dramatic collapse in ice cover in one year is highly unusual. I'm not saying that this is or isn't a normal event or part of a cyclical cycle. I think in either case, the problem is that we built cities so close to water and in areas that, for example, should have stayed swamp land. This will cause major problems with sea levels whether it's a normal cycle or not.

  • Basing global warming predictions and the melting of the ice caps on less than 100 years reliable worldwide weather data is completely unscientific and nonsense.

    The earth is billions of years old. We currently are still in an ice age that began 2.6 million years ago. Your talk about global warming destroying the ice caps is nonsense. There have been at least 5 major ice ages in the Earth’s past (the Huronian, Cryogenian, Andean-Saharan, Karoo Ice Age and the Quatenary glaciation cover. hundreds of millions of year.
    And, the melting of the ice caps is one of the normal warming processes the earth goes through; but these processes take millions of years, hundreds of millions of years; and, unfortunately no one was alive to record the events.
    One of the last warming periods was the Cretaceous period, about 145-66 million years ago that lasted 80 million years. Man cannot stop or change these periods. The earth will continue to experience new ice ages followed by periods like the Cretaceous period where the ice caps melt substantially. All these ices ages and warming periods happened millions of years before man was on earth and will continue, millions of years after man is no longer on this earth.
    The Cretaceous was a period with a relatively warm climate, resulting in high Eustatic sea levels and creating numerous shallow inland seas that covered much of what is now the USA. The tropical sea surfaces may have been as warm as 107 F (Fahrenheit), the average now is 99 F. Meanwhile deep ocean temperatures were as much as 27 to 36 degrees F higher than today.
    The current atmospheric carbon dioxide level in January 2013 was 395.55 ppm. During the Cretaceous period it was 1,700 ppm or over 4 times as high. So, please stop blaming man because you do not know what you are talking about.
