From Hawaii to an Icecube


By Alexandre Aguiar – MetSul Weather Center (Brazil) and ICECAP contributor

Tuesday, February 17th, mid afternoon in Latin America. News wires by the Spanish news agency EFE report a massive collapse of the Wilkins Ice Shelf in Antarctica. The news quickly appeared in the front pages of electronic editions of newspapers all over Latin America and Europe. “Iceberg larger than Hawaii has broken off in Antarctica” was the headline. The news said: “A 14,000 square km shelf of ice, almost twice the area of the Basque Country, has broken off the Wilkins Ice Shelf in the Antarctic. Scientists believe the ice shelf is crumbling as a result of global warming. The Spanish National Research Council (CSIC) has reported today that the resulting giant icebergs are now floating around in the Antarctic Ocean. A team of CSIC scientists have been in the area investigating the impact of the crumbling ice shelf on the ecosystem in the Belinghausen Sea, to the west of the Antarctic peninsula. Over the past two weeks, the scientists have seen the ice shelf on the edge of the Belinghausen Sea recede 550km and have noted that the water temperatures are extraordinarily warm in this area. Experts have warned that the breaking away of this massive ice shelf will ultimately have notable consequences on the sea level.


CSIC scientist, Jordi Dachs, reported that his team had found ‘a very high level of biological production’ in the areas where the fragments of ice have gone and that there is ‘abundant fauna, with the largest concentration of humpback whales and leopard seals’ they have seen up until now. ‘We have also found very low levels of CO2 in the sea water’ he continued, ‘suggesting that the increase in sunlight getting through and the elements released by the breaking ice fertilize the water’.”

My suspicion on the news was immediate. How do you detect a 14 thousand square kilometer ice breakdown from a boat. Why weren’t the satellites not showing such a huge event ? Well, later in the day the news had a different version. The Spanish CSIC clarified the collapse was not so large as previously informed. Suddenly, the headlines changed.

But it was not the end of the story. Wednesday, February 18th, mid afternoon in Latin America. News wires by the German news agency DPA report there was not a collapse observed in the Wilkins Ice Shelf. According to DPA, several German researchers assured today that pictures from the German satellite Terrasar and the European Envisat reveal no evidence of a break-up of the 14 thousand kilometers ice platform. The information was released by Professor Angelika Humbert from the University of Munster. Also, Professor Heinrich Miller from the Alfred-Wegener Institute in Bremerhaven dismissed a total collapse. Even the alarmist group Greenpeace said today there was no information on the alleged massive event reported by the Spanish in the South Pole. What was larger than Hawaii, in fact, became an embarrassing ice cube.

Icecap Note: the peak of the Southern Hemisphere Melt season is still a month ahead. We should not be surprised to see chunks calving off the icesheet or even more cracking in the western Wilkins ice sheet. This is a normal process that has gone on throughout history. It is only now with satellite and funded coastal studies are we documenting these natural processes.

It’s funny. At Watts Up With That I made this comment about the Wilkins ice shelf breaking up with a link to a Times online story of a 160 sq mile chunk breaking off back in Mar 2008.

Vast iceberg breaks off Wilkins Ice Shelf in Antarctic

Satellite images have revealed that about 160 square miles of the Wilkins Shelf have been lost since the end of February, suggesting that climate change could be causing it to disintegrate much more quickly than scientists had predicted. “The ice shelf is hanging by a thread,” said David Vaughan, of the British Antarctic Survey(BAS). “We’ll know in the next few days or weeks what its fate will be.” …
… The Wilkins Shelf is now protected by only a thin thread of ice between two islands. It covers an area of 5,600 square miles (14,500 sq km).

“Somethings not right here. I read through that whole article by the Times, and not once did it quote Walt Meier on how the break up of 14k sq. km isn’t news worthy.”

The comment was made in reference to Walt Meier of NSIDC’s comment to Anthony,
“I’m not sure why you think things like this [a millions sq. kilometers of Arctic sea ice missing from the NSIDC’s graph] are worth blogging about. Data is not perfect, especially near real-time data. That’s not news.”, on the thread Errors in publicly presented data – Worth blogging about?

I’n sure it’s just a coincidence. Funny one though.
