<p>“Our study confirms many changes seen in upper Arctic Ocean circulation in the 1990s were mostly decadal in nature, rather than trends caused by global warming,” said Morison.</p>
<p>
</p>
<p>He seems to be assuming the reality of climate change, based on scientific study, while fine-tuning the understanding of observations associated with it. Sounds like the way good scientists work.</p>
<p>yes, of COURSE we can trust Nasa</p>
<p>they have no record EVER of trying to block or stall or silence those that disagree</p>

<p>so Bush people will match the research to the nswer the Administration wants, gee, what a novel thought!!!</p>
<p>And Morrison goes on to say, “The events of the 1990s may well be a preview of how the Arctic will respond over longer periods of time in a WARMING world,” </p>
<p>Nice try bandit_TX.</p>
<p>so morison got in the word warming, good for him!!!</p>
<p>seriously, the NASA reports are passed through some minions of Bush</p>
<p>CGM: is it your nature to be so cynical at everything US gov’t does ?</p>
<p>I expressed some doubts about global warming to my friend of 20 years, he was so angered he was ready to end our friendship. ;-)</p>
<p>“I expressed some doubts about global warming to my friend of 20 years, he was so angered he was ready to end our friendship.”</p>
<p>This is nothing compared to the story I read. One of the republican congressman from NC (?) changed his stand on global warming after his son threatened him that he will not vote for him.</p>
<p>“CGM: is it your nature to be so cynical at everything US gov’t does ?”</p>
<p>After the stuff Bush administration has done every one except the die hard supporters are that cynical.</p>
<h2>Let’s put all of the above parsed statements in proper context:</h2>
<p>Our study confirms many changes seen in upper Arctic Ocean circulation in the 1990s were mostly decadal in nature, rather than trends caused by global warming," said Morison. </p>
<p>“While some 1990s climate trends, such as declines in Arctic sea ice extent, have continued, these results suggest at least for the ‘wet’ part of the Arctic – the Arctic Ocean – circulation reverted to conditions like those prevalent before the 1990s,” he added. </p>
<p>The Arctic Oscillation was fairly stable until about 1970, but then varied on more or less decadal time scales, with signs of an underlying upward trend, until the late 1990s, when it again stabilized. During its strong counterclockwise phase in the 1990s, the Arctic environment changed markedly, with the upper Arctic Ocean undergoing major changes that persisted into this century. Many scientists viewed the changes as evidence of an ongoing climate shift, raising concerns about the effects of global warming on the Arctic. </p>
<p>Morison said data gathered by Grace and the bottom pressure gauges since publication of the paper earlier this year highlight how short-lived the ocean circulation changes can be. The newer data indicate the bottom pressure has increased back toward its 2002 level. “The winter of 2006-2007 was another high Arctic Oscillation year and summer sea ice extent reached a new minimum,” he said. “It is too early to say, but it looks as though the Arctic Ocean is ready to start swinging back to the counterclockwise circulation pattern of the 1990s again.” </p>
<p>Morison cautioned that while the recent decadal-scale changes in the circulation of the Arctic Ocean may not appear to be directly tied to global warming, most climate models predict the Arctic Oscillation will become even more strongly counterclockwise in the future. “The events of the 1990s may well be a preview of how the Arctic will respond over longer periods of time in a warming world,” he said. </p>

<p>Only time will tell…but at least we’ll know before Al Gore dies if he was a fool or not. (Or rather, if WE were the fools or not. ;))</p>
<p>“Or rather, if WE were the fools or not.”</p>
<p>I already know. We are the fools.</p>
<p>lol…simba. That’s how ‘I’ feel these days…sigh.</p>
<p>who cares well all be dead before we begin to notice the effects of global warming.</p>
<p>ah, its people like uriA702- who invision the future that make the world such a wonderful place</p>
<p>and yes, one must be cynical- its better to be cyncial then to follow lockstep</p>
<p>and when you have former Nasa employees, and employees from many many agencies whose work is clouded because it is handled by Bush appointees who don’t know what they are doing, but are making sure the information that gets out matches the Bush agenda, a healthy dose of cynism is mandatory</p>
<p>and yourworld, do you believe everything this administration tells you?</p>
<p>and it is wonderful that 20 years ago a person didn’t believe in global warming- going against the science is sucha smart way to be</p>
