Without the habitat available for life to perpetuate. It is a point in Earth geological time scale and biggest opportunity ever. Realization that our gross exploitation of sequestered carbon for fuel and to make product for war and consumerism including chemical fertilizer is to blame and results in present moment in time and accurately describing it has power to awaken the public outcry.. There is game on 2C if change can be triggered to link valuation of monetary worth to its affect on preserving the essence of Nature and our home.<br />The opportunity is there if we seize it to make alteration to world monetary worth to enable creation of what amounts to an open and naturally tending toward stability and living within means system that has checks and balance as natural tendency -to confront the pressure toward extinction brought by the thermodynamic tendency of an otherwise closed system to increase in disorder or heat.<br />It is my contention the will to live is dominant if there is still time to change.Dale Lananhttps://www.blogger.com/profile/05409842680440987251noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-54917771670074967072012-08-27T02:20:42.151-07:002012-08-27T02:20:42.151-07:00Yes, I always like to see sources and references a...Yes, I always like to see sources and references added, but perhaps this simply refers to the work of Dr. Wieslaw Maslowski, of the Naval Postgraduate School, a research university operated by the United States Navy, who has been collecting submarine data on sea ice thickness for years, and who concluded in 2007 that Arctic waters could be ice-free in summer by 2013. <br /><br />BTW, this was widely reported, e.g. by <a href="http://news.bbc.co.uk/2/hi/7139797.stm" rel="nofollow">the BBC</a>, and it obviously didn't fit in with the models used by many climate scientists, who to date still refuse to acknowledge that their models, by either using a limited dataset or by averaging things out globally and over long periods, masks the rapid changes in the Arctic.

Indeed, the often-used exponential projection is made by Wipneus, based on PIOMAS volume data, is discussed at <a href="http://arctic-news.blogspot.com.au/2012/08/getting-the-picture.html" rel="nofollow">Getting the picture</a>. NSIDC's graphs depict sea ice extent, which hasn't dropped as dramatically as thickness, but which looks set to collapse soon, as also described in <a href="http://arctic-news.blogspot.com.au/2012/08/getting-the-picture.html" rel="nofollow">Getting the picture</a>.Sam Caranahttps://www.blogger.com/profile/12376449209858411775noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-89408478641924468652012-08-26T19:21:32.952-07:002012-08-26T19:21:32.952-07:00Also, IIRC the PIOMAS scientists do not make a pro...Also, IIRC the PIOMAS scientists do not make a projection for 2015, rather it's an extrapolation by others.Steve Bloomhttps://www.blogger.com/profile/12943109973917998380noreply@blogger.comtag:blogger.com,1999:blog-3046701423623795423.post-1651185835851558802012-08-26T19:18:50.149-07:002012-08-26T19:18:50.149-07:00Pointer to that Cialeaks info, please?
Re why sci...Pointer to that Cialeaks info, please?<br /><br />Re why scientists who rely substantially on GCMs tend not to agree with projections of abrupt change, it's because GCMs don't really do abrupt change. It's a problem. Of course such scientists by no means deny the prospect, since among other things paleoclimate examples abound, but if the physics isn't understood they don't want to stick their necks out.
