New Times Atlas vastly overstates Greenland ice sheet shrinkage

You know it’s a major gaffe when even the BBC’s Environment correspondent is saying things like this:

The part of News Corporation that makes Times Atlases is currently taking the same kind of kicking from scientists that some of its newspapers took from the general public over phone-hacking.

What it’s being kicked for is for claiming, in the edition that came out last week, that the Greenland ice sheet has shrunk by 15% over 12 years, necessitating the re-drawing of its boundaries.

[. . .]

The problem is, it’s not true; and glaciologists have been queuing up to say why not.

“In the aftermath of ‘Himalayagate’, we glaciologists are hypersensitive to egregious errors in supposedly authoritative sources,” said Graham Cogley from Trent University in Canada.

“Climate change is real, and Greenland ice cover is shrinking. But the claims here are simply not backed up by science; this pig can’t fly.”

As Professor Cogley was the scientist who raised the alarm over “Himalayagate” — the erroneous Intergovernmental Panel on Climate Change (IPCC) contention that Himalayan glaciers could largely melt away by 2035 — he is well placed to make the comparison.

Update: Breaking! James Delingpole discovers the advance plans for the next Times Atlas:

Following its controversial decision to produce a map suggesting that Greenland has lost 15 per cent of its ice cover in the last twelve years — a loss rate disputed by most credible scientists: and even, amazingly, the Guardian agrees on this — the Times Comprehensive Atlas Of The World has decided to take its new role as cheerleader for Climate Change alarmism a step further. In its upcoming 14th edition, unconfirmed rumours suggest, it will completely omit Tuvalu, the Maldives and major parts of Bangladesh in order to convey the “emotional truth” about “man made climate change.”

“All right, it may not be strictly geographically accurate to say the Maldives and Tuvalu will definitely have disappeared in about ten years time when our next edition appears,” said Times Atlas spokesman David Rose. “But did you see that picture of the Maldives cabinet holding a meeting underwater? If the Maldives government says the Maldives are drowning, they must be drowning. And frankly I think it’s despicable, all those deniers who are saying it was just a publicity stunt, cooked up by green activist Mark Lynas, to blackmail the international community into giving the Maldives more aid money while simultaneously trying to lure green Trustafarians to come and spend £1500 a night in houses on stilts with gold-plated organic recyclable eco-toilets made of rare earth minerals from China. Why would a government lie about something as serious as climate change?”

More on the Greenland settlements

Filed under: Americas, Environment, History — Tags: , , , — Nicholas @ 12:08

In a follow-up to yesterday’s post on the end of the Viking settlements in Greenland, Sonya Porter provides more historical background:

In 891 AD. Eric The Red set off from Iceland with a few followers to explore a land to the west which they had probably spotted some time before while sailing out in their longboats, and then returned three years later with about 500 fellow Vikings. At first they settled on the south-east coast, close to the tip of this new land and then, as the population grew, created a further settlement to the south-west. They called their new home ‘Greenland’.

It has been said that this name was a ‘spin’, a publicity stunt to entice more Vikings to come to join the new settlers, but this would have been pointless if it had been impossible for them to survive. They must at least have been able to create their own dwellings, build their own fires, make their own clothes and above all, grow their own food. The settlers might have been able to trade such things as polar bear-skins and fox furs for iron and other necessities on occasional trips to Europe, but their compatriots in Denmark and Iceland would have been neither able nor willing to row their longboats out each month with groceries.

At present, the temperatures in Greenland range from a maximum of 7C in July to -9C in January. This is too cold for grain such as wheat and even rye to grow and ripen in the short summer of such northern latitudes. Nor are sheep and cattle happy at those temperatures. Hill sheep might be able to nibble away at moss and short grass, but cattle need lush meadows and hay to fatten and live through a winter. Solid wood is needed for building, boat building and warmth, but only bushes and such weak trees as birch now grow in Greenland.

In 1991, two caribou hunters stumbled over a log on a snowy Greenland riverbank, an unusual event because Greenland is now above the treeline. (1) Over the past century, further archaeological investigations found frozen sheep droppings, a cow barn, bones from pigs, sheep and goats and remains of rye, barley and wheat all of which indicate that the Vikings had large farmsteads with ample pastures. The Greenlanders obviously prospered, because from the number of farms in both settlements, whose 400 or so stone ruins still dot the landscape, archaeologists guess that the population may have risen to a peak of about five thousand. They also built a cathedral and churches with graves which means that the soil must have been soft enough to dig, but these graves are now well below the permafrost (2).

A bit of climate-change panic juxtaposition

First, the panic:

In a world of climate change, freak storms are the new normal. Newsweek‘s Sharon Begley on why we’re unprepared for the harrowing future, and how adapting to the inevitable might be our only option.
[. . .]
From these and other extreme-weather events, one lesson is sinking in with terrifying certainty. The stable climate of the last 12,000 years is gone. Which means you haven’t seen anything yet. And we are not prepared.

And, in the interests of balance, the eeeevil climate change denier:

Greenland’s early Viking settlers were subjected to rapidly changing climate. Temperatures plunged several degrees in a span of decades, according to research from Brown University. A reconstruction of 5,600 years of climate history from lakes near the Norse settlement in western Greenland also shows how climate affected the Dorset and Saqqaq cultures. Results appear in Proceedings of the National Academy of Sciences.

PROVIDENCE, R.I. [from Brown University] — The end of the Norse settlements on Greenland likely will remain shrouded in mystery. While there is scant written evidence of the colony’s demise in the 14th and early 15th centuries, archaeological remains can fill some of the blanks, but not all.

What climate scientists have been able to ascertain is that an extended cold snap, called the Little Ice Age, gripped Greenland beginning in the 1400s. This has been cited as a major cause of the Norse’s disappearance. Now researchers led by Brown University show the climate turned colder in an earlier span of several decades, setting in motion the end of the Greenland Norse.
[. . .]
The researchers also examined how climate affected the Saqqaq and Dorset peoples. The Saqqaq arrived in Greenland around 2500 B.C. While there were warm and cold swings in temperature for centuries after their arrival, the climate took a turn for the bitter beginning roughly 850 B.C., the scientists found. “There is a major climate shift at this time,” D’Andrea said. “It seems that it’s not as much the speed of the cooling as the amplitude of the cooling. It gets much colder.”

The Saqqaq exit coincides with the arrival of the Dorset people, who were more accustomed to hunting from the sea ice that would have accumulated with the colder climate at the time. Yet by around 50 B.C., the Dorset culture was waning in western Greenland, despite its affinity for cold weather. “It is possible that it got so cold they left, but there has to be more to it than that,” D’Andrea said.
