Slowing jet stream shows risk from warming Arctic

[phantom power]

LONDON, Sept 28 (Reuters) - A new, unpublished finding that the polar "jet stream" is slowing down provides compelling evidence of a link between rapidly melting Arctic sea ice and colder winters across the northern hemisphere and other extreme weather.

...

Slower winds could affect the weather in two ways.

First, a slower jet stream takes a more meandering path which shifts more slowly. That can create more persistent weather conditions including floods or droughts.

Second, the meandering path tends to adopt a pattern which diverts cold air over the eastern United States and western Europe, in a paradoxical impact of global warming, reinforcing a negative phase of a well-known natural weather cycle called the North Atlantic Oscillation (NAO).

1. Scary-

Wasn't that the scenario in that movie: Day after Tomorrow?
Yikes.

evidence of this...... Melting ice sheets in Greenland = more fresh water in the north Atlantic = equals thermohaline current submerging sooner = cooler, colder weather. Ah the ironies of global warming and the stupidities of homo-so-called-sapiens. Ms Bigmack

Need to keep an eye on this - if verified then ... oops?
