The vast majority of climate-related articles (and comments) on blogs/websites seem to incessantly, and mistakenly, assume some kind of linearity that really hasn't been observed. Only on short, "specific" intervals does an exponential curve appear "linear." For more than 5 years I've been trying to relay the message that I think it highly-likely that the WAIS is already unstable and approaching (at?) a point where 5-10% of it may collapse raising sea-levels, on average, 1-2 feet. This in turn is very-likely to trigger 1) more ice-SHELF collapse, leading to accelerating glacier-flow-rates and 2) a substantial acceleration of Greenland's 4 largest and fastest-flowing glaciers, both of which will only enhance SLR by a further 1-2 feet. A close examination of shoreline-elevations, available through more than a few sources, reveals that 2-4 ft of SLR has the potential, in just the USA, to make 10-20 million [more] people 1) homeless, 2) jobless or 3) both, practically "overnight." The "chain-reaction" of consequences which follow, if it were to happen in the next 5-10 yrs (VERY likely), are almost unimaginable beyond being very "unpleasant." I look forward to reading more of your thoughts. (I just found you via a comment you made to an article on DiscoveryNews.)]]></description> <content:encoded><![CDATA[<p><strong>At last!!</strong><br />Mr. Englander, this is perhaps the most lucid and RELEVANT article on SLR and the WAIS that I have seen… anywhere!
