Worried about sea level rise? Just pump seawater up into the middle of Antartica, it will freeze and reduce sea level and no need to desalinate. The central Arctic never gets warm enough for ice to melt, at best it sublimes (like Greenland apart from a surface melting about every 150 years, one of which is happening now).
But all this sea level concern appears overblown. There is nothing in current trends to suggest any anomalous or accelerated rise in fact last 5 years it has almost stopped: http://milo-scientific.com/pers/essays/gwfig4.php Most of the Holocene was warmer than the last 2000years, and sea levels were frequently higher, it is no surprise that it is rising coming out of the little ice age that ended about 200 years ago. In recent decades there has been about 25% of sea level rise caused by ground water abstraction for agriculture (0.8mm/year out of about 3mm) - but the current 3mm/year rise is no faster than it was 70 years ago before CO2 driven global warming supposedly became a factor, so underlying sea level rise is likely lower than it was 70 years ago. http://nextgrandminimum.wordpress.com/2011/10/14/hiding-the-inconvenient-satellite-sea-levels-where-is-the-water-going/sea_level_rise/ On 30 July 2012 21:20, David L Babcock <[email protected]> wrote: > On 7/30/2012 3:27 PM, Chemical Engineer wrote: > >> It seems to me that if LENR is real and scalable and we have approx 50 >> years to turn things around, some new industries that should arise, based >> upon sound scientific data are: >> >> 1) Cooling of oceans to stable, pre-industrial temperatures using >> evaporative cooling, etc requiring lots of LENR pumping HP, which is now >> virtually free >> 2) .... >> 3) ... >> >> >> And big ass LENR pumps for all the cities to keep the water out until 1-3 >> are effective. >> >> > I at first missed the word "cities" > So had a brief vision of thousands of (will be) former beach dwellers now > looking at the ocean with closed circuit TV, from the bottoms of their 100 > foot tall cast cement silos, while huge pumps howl to keep their patches of > sand dry. > > Keeping Manhattan dry -not to mention Brooklyn and Staten Island!- will > surely be easier, but just as surely totally uneconomical.
