Ocean currents causing arctic melting...? ...at least some of it, according to this article in the New Scientist (normally a very pro-global warming magazine):

Apparently a cyclical ocean current could explain a lot of the unexpectedly fast melting of ice in the arctic. A change in water flow is directing warm air towards the arctic which is causing some of the melting.

This warming of the arctic also means less heat from other parts of the northern hemisphere is lost. The article goes on to say that this effect could account for 0.2 of the 0.5 oC of warming seen in the NH in the past 30-odd years. So 0.1oC of the global temperature change.

Obviously, that is a highly significant proportion. So, what do you think?
