I read an article today, I came to know that warming ocean can melt ice faster at poles. What I want to know that how could warm ocean melt ice faster at poles? Does someone have answer to my question?

    Warming air from climate change isn't the only thing that will speed ice melting near the poles; so will the warming water beneath the ice. Increased melting of ice in Greenland and parts of Antarctica has been reported as a consequence of global warming, potentially raising sea levels. But little attention has been paid to the impact of warmer water beneath the ice. Jianjun Yin of the University of Arizona and colleagues report the warming water could mean polar ice melting faster than had been expected. While melting floating ice won't raise sea level, ice flowing into the sea from glaciers often reaches the bottom, and grounded ice melted by warm water around it can produce added water to the sea. "Ocean warming is very important compared to atmospheric warming because water has a much larger heat capacity than air". If you put an ice cube in a warm room, it will melt in several hours. But if you put an ice cube in a cup of warm water, it will disappear in just minutes. In addition, Yin explained, if floating ice along the coastal areas melts it will allow the flow of glaciers to accelerate, bringing more ice into the seas. Over peck, co-director of the University of Arizona's Institute of the Environment, said: "This paper adds to the evidence that we could have sea level rise by the end of this century of around 1 meter and a good deal more in succeeding centuries." The subsurface ocean along the Greenland coast could warm as much as 3.6 degrees Fahrenheit (2 Celsius) by 2100, the researchers reported. The warming along the coast of Antarctica would be somewhat less, they calculated, at 0.9 degree F (0.5 C).
