Register: Greenland's glaciers speed a little, Bering Sea ice hits brief record, Greenpeace is band of fear-mongering hippies.

Lewis Page, at the UK tech news outlet The Register, is a standout largely on the strength of his devotion to all things boffin. Some others at the Register including Lester Haines -here's a strange, stiff(y) non-boffin one from him the other day, good for adolescent laughs - tend toward labeling everybody with an advanced degree a boffin. It is a retro-term of fuzzy origin applied in WWII to England's radar and proto-computer nerds. But nobody out-boffins Page.From him, you can count on a boffin as reliably as you find the family dog on top of a car in a Gail Collins reference to Romney.

This morning after wondering about the handling of news in last week's Science that Greenland's glaciers are not speeding up as much as earlier evidence implied -- I'll get momentarily to a roundup -- I came across this version:

As he writes, between a ref. to boffins and to boffinry, a report from the Univ. of Washington and from Ohio State U's famed Polar Research Center says that a careful look at a passel of southern Greenland's outlet glaciers finds they are indeed speeding up. But it is not enough to enforce earlier predictions they alone could raise global sea level by nearly 20 inches or much more than that in this century. Four to seven inches still fits the data. Bad enough, not in itself disastrous (depends on where one lives of course). But then he throws in this, as reflected in the hed: "Just a few years ago, the fear mongering hippies* at Greenpeace were bandying a wild figure of seven meters about."

Fear mongering gets a pass. But Hippies, say what?! Sure some of them look kind of hippyish, long haired and perhaps not averse to the occasional doobie, but a bunch of slackers mumbling mantras and having an irritating amount of sex and suffering no lightning bolts despite all the beards and beads like in the late 1960s? C'mon. That preceding quote's asterisk is Page's. It leads one to another, recent Page yarn (including two more boffin mentions) that persuasively argues that Greenpeace itself has at least one employee who tells the newbies when they join up to chase whalers and things like that: ".. you're in Greenpeace now "... Which means you're hippies ... hold on to your hippy heart."

That's pretty for such a gratuitous and in many quarters dismissive label, citing Greenpeace staff's utterances. One last thing before moving on to more Greenland ice coverage. Page's documentation for the hippy crack ran earlier this month in a story under the hed: Amount of ice in Bering Sea reaches all-time record / Hippies get it  wrong again ;

Aside from the hippy part that story last month is still worth noting. It made much of the high ice level in the Bering Sea between Alaska and Russia. Unfortunately, he writes it as though that means something in a vein reminiscent of those goofy contrarians who chortle such things as Record Snow Storm and So Much for Al Gore, you Socialist Data-Distorters Har Dee Har Har. He cites a report from the US's National Snow and Ice Data Center and selects a quote from it to support his angle on recent icemelt. Here's this month's version of the  same report. Note that it emphatically declares that the onset of the melt season each spring is often erratic and is no guide to how low sea ice will go by the end of summer. Furthermore, data maniacs, the most recent plot of fluctuating northern sea ice is among the weirdest to be found. It reveals almost no melting at all from March to mid-April followed by an exceedingly steep plunge in the last week or two. Weather lately is a spectacle.

Other Greenland Glacier + Sea Level News: Good news, bad news, all depends on where you start. Several news outlets also imply that a slower rate leads to less, ever. It would be good if somebody had asked whether the slower rate is also indicative of anything regarding the eventual, centuries-hence equilibrium level for a more exposed Greenland. It's natural to focus on what will happen within our grandchildren's lifetimes but the ultimate result is worth a question and the sharing of its answer.

Closer reading of the details of the SCIENCE story shows that the authors "suggest" the ice loss may be lower than previously discussed by other. The word "suggests" is critical. The authors did not carry out a mass balance study. They looked at surface ice velocity. They also did not look at temperature and melt rates for various parts of Greenland nor the ice melt from relatively warm ocean currents under the ice sheets. The GRACE satellite provides some details on mass balance. There are the elements that could be included in the "future research" they suggest.

Science: "Our wide sampling of actual 2000 to 2010 changes shows that glacier acceleration across the ice sheet remains far below these estimates, suggesting that sea level rise associated with Greenland glacier dynamics remains well below the low-end scenario (9.3 cm( 4inches) by 2100) at present. Continued acceleration, however, may cause sea level rise to approach the low-end limit by this century’s end. Our sampling of a large population of glaciers, many of which have sustained considerable thinning and retreat, suggests little potential for the type of widespread extreme (i.e., order of magnitude) acceleration represented in the high-end scenario (46.7 cm by 2100). Our result is consistent with findings from recent numerical flow models (34)."
Also note worthy is the very short time period used for the study: 10 years.
"Despite the extent of our observations, this remains a glaciologically short record, and efforts in modeling and statistical extrapolation will benefit as the period of observation lengthens."
Still a very interesting study using important satellite observations.
