If this is true, it looks like a harsh winter for the E coast of N.America and Europe.
Quote:"The North Pacific hasn't been this warm ever, as far as anyone knows. It's really strange," said Bill Peterson, oceanographer with NOAA's Northwest Fisheries Science Center in Newport, Ore. "It looks like an El Nino, but it really isn't. We don't really know what it is."
Quote:Hence the forecasting of future climate relies partly on the answer to this question: How long does the ocean store heat before dumping it back into the atmosphere? Normally, ocean currents circulate the heat vertically and horizontally throughout the sea, from pole to pole, much as cooling fluids circulate through a refrigerator or air conditioner.
A slight disruption in currents can bring climate change.
Quote:The warming is especially strange because the deep waters of the North Pacific are an old folks' home of the global ocean -- a sluggish, bone- chilling abyss where, according to theory, nothing happens very fast. Here are some of the world's "oldest" oceanic waters, about 800 years old. That is, they began sinking from the ocean surface to the seafloor during the days of the Vikings.
Or so scientists assumed. Now, the Nature article reports that by some unknown means and much faster than assumed, the solar-heated water is finding its way to the ocean floor in decades, not centuries. In fact, the researchers estimate it reached the bottom within 50 years.
The Fukasawa team's findings show a warming in the deep North Pacific over a "shorter time scale and larger spatial scale than (has) ever been believed," Fukasawa said in an e-mail. "As (far) as I know, our result is the first which shows such a large-scale temperature change in the global thermohaline circulation," that is, in global heat and salt circulation via ocean currents.

I'm pretty sure they're not going to look into that.

If the question arises they will, but the results may be skewed. lol.
