The chief investment officer of its reserve management department is Changhong Zhu, until recently head of derivatives for the hedge fund operations of the giant US financial group PIMCO, and viewed as one of the 'rock stars' of the global hedge fund industry.

Well, maybe. I just googled it and came up with this site but not much else.

$this->bbcode_second_pass_quote('pstarr', 'D')idn't I hear that the Atlantic conveyor, the planetary ocean current system that brings warm Gulf Stream waters north, is starting to fail? That could account for these extreme weather events. The movie "Day After Tomorrow" was actually based on reasonable scientific conjecture, first posited at the Woods' Hole Oceangraphic Institute.


The global thermohaline circulation is the oceanic overturning mode, which is manifested in the North Atlantic Ocean as northward-flowing surface waters which sink in the Nordic (Greenland, Iceland and Norwegian) seas and return southwards—after overflowing the Greenland–Scotland ridge—as deep water. This process has been termed the 'conveyor belt', and is believed to keep Europe 5–8 °C warmer than it would be if the conveyor were to shut down1. The variability of today's conveyor belt is therefore an important component of climate regulation. The Nordic seas are the only Northern Hemisphere source of deep water and a previous study3 has revealed no long-term variability in the outflow of deep water from the Nordic seas to the Atlantic Ocean. Here I use flows derived from hydrographic data to show that this outflow has approximately doubled, and then returned to previous values, over the past four decades. I present evidence which suggests that this variability is forced by variability in polar air temperature, which in turn may be connected to the recently reported Arctic warming4.

The Arctic Oscillation

The Arctic Oscillation refers to opposing atmospheric pressure patterns in northern middle and high latitudes.

The oscillation exhibits a "negative phase" with relatively high pressure over the polar region and low pressure at midlatitudes (about 45 degrees North), and a "positive phase" in which the pattern is reversed. In the positive phase, higher pressure at midlatitudes drives ocean storms farther north, and changes in the circulation pattern bring wetter weather to Alaska, Scotland and Scandinavia, as well as drier conditions to the western United States and the Mediterranean. In the positive phase, frigid winter air does not extend as far into the middle of North America as it would during the negative phase of the oscillation. This keeps much of the United States east of the Rocky Mountains warmer than normal, but leaves Greenland and Newfoundland colder than usual. Weather patterns in the negative phase are in general "opposite" to those of the positive phase, as illustrated below.

So that is why the US was hit by three Blizzards in one winter when these storms are usually a once a decade event. Maybe 6ft of snow in Washington, Phily, and New York will make the US take climate change seriously.

I have noticed the opposite, right wingers claiming this is evidence that global warming is a fallacy.

Wow, didn't take you long to stick the AGW-tard label on a snow storm!

Uh, I think the rise in violent and serious weather Gore was spouting off about in his award winning science fiction has been thoroughly debunked - check your propaganda material, there have probably been memos you missed.

Someone like you might fit right in with the cops smacking kids down for throwing snowballs though!

Notice I didn't say global warming but climate change. The last few thousand years in terms of climate has been very stable. There has been studies on ancient tree ring data and ice cores that show climate chaos is possible where both harsh winters with blizzards and summers filling the tropics with hurricanes can become the new normal. I don't read propaganda but deal in real science. Go do some research on the lesser dryas period when the last time the climate went into whiplash mode because of the shutdown of thermohaline circulation.

I had a similar thought. My boat is in Newfoundland and I watch the temps there pretty frequently. They have been running just about freezing, fairly consistently warmer than Philly. This change in the stream, if it pans out, would seem to fit with that.
