That seems the reason there is not much interest.<br />also if we are talking 200 years, the global temp might be 4-6° higher than now so the decrease in Europe would not be that great compared to now. thinking there will be other things of greater concern then.<br />tonylearnshttps://www.blogger.com/profile/15168161576867493109noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-19961322661890199422014-12-10T04:15:44.466+11:002014-12-10T04:15:44.466+11:00I haven't checked on the data lately and don&#...I haven't checked on the data lately and don't have time to do so just now, but IIRC the AMOC had been determined to be significantly slowing recently. There was a bit of a kerfuffle when the initial data pointing to this (based on a new sensor array) came out about 5 years back, including an RC post that concluded it was too early to panic and that we should wait and see if subsequent data supported a trend. Well, when the data did just that there was barely a ripple of reaction in the news media or even the blogosphere. I found that very strange. Of course even assuming that the most recent data continues the trend, it's still early days. <br /><br />"...if the injection of fresh water were to increase substantially from what is happening at present."<br /><br />There's no "if" about it. Just look at the GRACE mass loss data trend for the Greenland ice sheet and note especially that the NE Greenland glaciers, until very recently thought not to be very sensitive to current warming, have undergone a sharp acceleration of ice loss in the last few years. This latter actor is crucial since those glaciers are far less kinematically constrained than many of the other big ones elsewhere in Greenland (IOW they reach the sea via much larger "gates" that make for poor brakes on ice loss acceleration).<br />Steve Bloomhttps://www.blogger.com/profile/12943109973917998380noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-11429106513775702622014-12-10T03:55:59.567+11:002014-12-10T03:55:59.567+11:00*Northern* Europe.

I used to frequent there, but gave up on BA months ago as it is an unmoderated food fight. Some of the denialists have been running 2 or 3 socks over there for a long time, every post being the functional equivalent of "Nyah, nyah warmists! You suck."

Anyway I was going to add that this reminds me of another AMOC shutdown study but instead deals with paleoclimate modeling that injected a large amount of freshwater from Lake Agassiz using the MIT GCM. 5 Sverdrups at once versus the maximum of .4 Sv per year in this study. It really puts studies like this Boulton paper into proper context. <br /><br />http://www.pnas.org/content/109/49/19928.abstract<br /><br />My original comment was unrelated to the article and had to do with some astroturfing I've been seeing from the WUWT crowd. I've been going back and forth with Rick Cina over at livescience for the past week now and it's obvious he's either being paid per post by Anthony Watts or actively encouraged. He also goes by the name kennethrichards@WUWT. Anyway pop over there and read some of his comments if you want a good laugh. <br /><br />http://www.livescience.com/48880-antarctica-sea-ice-thickness-mapped.htmlChase Shttps://www.blogger.com/profile/04659478289426350280noreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-25986083474065225922014-12-09T05:53:08.334+11:002014-12-09T05:53:08.334+11:00All of science is based on modeling -- that's ...All of science is based on modeling -- that's the whole point: coming up with increasingly accurate models of how things work.<br /><br />Pseudo-science also works with models, but frees itself of the stifling limitation that models should be consistent with reality and with each other.numerobisnoreply@blogger.comtag:blogger.com,1999:blog-2313427464944392482.post-64987285344654844532014-12-09T05:36:49.696+11:002014-12-09T05:36:49.696+11:00This comment has been removed by the author.Chase Shttps://www.blogger.com/profile/04659478289426350280noreply@blogger.com
