Hotter 'n Drier

As jet streams move toward the poles, the tropics broaden their reach

WASHINGTON, May 25 — Deserts in the American Southwest and around the globe are creeping toward heavily populated areas as the jet streams shift, researchers reported Thursday.

The result: Areas already stressed by drought may get even drier.

A shift in where subtropical dry zones lie could make climate change locally noticeable for more people, said Karen Rosenlof, a NOAA research meteorologist also unconnected to the study.

''It is a plausible thing that could be happening, and the people who are going to see its effects earliest are the ones who live closer to the tropics, like southern Australia,'' said Rosenlof. Her own work suggests the tropics have actually compressed since 2000, after growing wider over the previous 20 years.

Reichler suspects global warming is the root cause of the shift, but said he can't be certain. Other possibilities include variability and destruction of the ozone layer. However, he and his colleagues have noted similar behavior in climate models that suggest global warming plays a role.

Moving the jet streams farther from the equator could disrupt storm patterns, as well as intensify individual storms on the poleward side of the jet streams, said co-author Qiang Fu, a University of Washington atmospheric scientist.

In Europe, for example, that shift could mean less snow falling on the Alps in winter. That would be bad news for skiers, as well as for farmers and others who rely on rivers fed by snowmelt.

''This definitely favors or enhances the frequency of droughts,'' Fu said of such a shift.

We go through our day to day lives with global warming somewhere in our psychee. But, no one really curbs their habits to play a part in decreasing the threats to our climate. What's REALLY Goin' on!

WASHINGTON, May 25 — Deserts in the American Southwest and around the globe are creeping toward heavily populated areas as the jet streams shift, researchers reported Thursday. Sounds to me like filler on a slow news day.

The result: Areas already stressed by drought may get even drier.

A shift in where subtropical dry zones lie could make climate change locally noticeable for more people Duh! Really!?, said Karen Rosenlof, a NOAA research meteorologist also unconnected to the study.

''It is a plausible thing that could be happening, and the people who are going to see its effects earliest are the ones who live closer to the tropics, like southern Australia,Australia is south of the equator, northern Australia is closer to the tropics'' said Rosenlof. Her own work suggests the tropics have actually compressed since 2000, after growing wider over the previous 20 years. and what does this mean, and this is the opposite of what the headline says

Reichler suspects global warming is the root cause of the shift, but said he can't be certain. Other possibilities include variability and destruction of the ozone layer. However, he and his colleagues have noted similar behavior in climate models that suggest global warming plays a role.

Moving the jet streams farther from the equator could disrupt storm patterns, as well as intensify individual storms on the poleward side of the jet streams, said co-author Qiang Fu, a University of Washington atmospheric scientist. It seems they are saying the poleward side of the jet stream is going to be wetter, not a drought condition.

In Europe, for example, that shift could mean less snow falling on the Alps in winter. That would be bad news for skiers, as well as for farmers and others who rely on rivers fed by snowmelt. Let's let everybody get upset about this so they will buy more of our newspapers. I have not seen anything about Global Warming from a creditable source that suggests it may increase or decrease rainfall globally, some areas will have more and some less, but the sky is not falling!!

''This definitely favors or enhances the frequency of droughts,'' Fu said of such a shift.

I don't really doubt that Global Warming is occuring and it will have some major local effects, but this kind of nebulous writing IMO is just crap. http://famulus.msnbc.com/famulusgen/...520061107#body

Heat? Thats good!

They keep going on about climate change, but when you are on the same lattitude as Moscow yet the coldest it gets is -5C, you tend to not care.

It gets colder, us Geordies can cope. It gets warmer, it will be down south and we Geordies will still have the cold winds from Siberia and Scandanavia to keep us cool

And orange groves, Anth - you'll love them!

I see Rameses was also impressed by the same statement that jumped out at me:

''It is a plausible thing that could be happening, and the people who are going to see its effects earliest are the ones who live closer to the tropics, like southern Australia,'' said Rosenlof.

The article seems somewhat garbled.

Possibly a typo. At any rate, laugh if you wish...it may be your children and grandchildren who suffer from this if it doesn't reverse. Orange groves don't grow in arid land. They tropics will move farther North, buy so will the deserts. Why do you think the Arctic icecaps are melting?

It does, doesn't it?

Tell us how you really feel, Bill!

So they got the geography wrong?

Interesting

Would newspapers and politicians lie about something like this? The 'Chicken Little, sky is falling' crowd is out in great numbers on this, aren't they?

Yes, it is nebulous and helps no one.

Good points, Bill. Thank you!
