Now tests show the ice ISN'T melting: Sea water under shelf in the East Antarctic is still freezing

Sea water under an East Antarctic ice shelf showed no sign of higher temperatures, first tests showed today.


Despite fears of a thaw linked to global warming that could bring higher world ocean levels, tests conducted on the Fimbul Ice Shelf showed the sea water is still around freezing point.


Thanks to sensors, lowered through three holes drilled in the shelf, scientists have discovered the water is not at higher temperatures widely blamed for the break-up of 10 shelves on the Antarctic Peninsula, the most northerly part of the frozen continent.

Tests: The Fimbul ice shelf, where scientists conducted experiments on the temperature of water there

After drilling through the shelf, which is between 250 metres and 400 metres thick, Ole Anders Noest of the Norwegian Polar Institute wrote in a statement: 'The water under the ice shelf is very close to the freezing point.


'This situation seems to be stable, suggesting that the melting under the ice shelf does not increase.'
The findings, a rare bit of good news after worrying signs in recent years of polar warming, adds a small bit to a puzzle about how Antarctica is responding to climate change - blamed largely on human use of fossil fuels.


Antarctica holds enough water to raise world sea levels by 57 metres (187ft) if it ever melted entirely, so even tiny changes are a risk for low-lying coasts or cities from Beijing to New York.

The Institute said the water under the Fimbul was about -2.05 degrees Celsius (28.31 Fahrenheit) - salt water freezes at a slightly lower temperature than fresh water.


And it was slightly icier than estimates in a regional computer model for Antarctica, said Nalan Koc, head of the Norwegian Polar Institute's Centre for Ice, Climate and Ecosystems.


'The important thing is that we are now in a position to monitor the water beneath the ice shelf,' she told Reuters.


'If there is a warming in future we can tell.'
She said data collected could go into a new report by the UN's Intergovernmental Panel on Climate Change, due in 2013-14.


The last IPCC report, in 2007, did not include models for sea temperature around the Fimbul Ice Shelf.


Experts have generally raised estimates for sea level rise - the United Nations spoke in late 2009 of a maximum 2 metre rise by 2100, up from 18-59 cms estimated by the IPCC in 2007 that excluded any possible acceleration from Antarctica.


The break-up of ice shelves does not in itself contribute to raise sea levels since the ice is already floating.


The risk is that pent-up glaciers on land will flow faster towards the ocean if the shelves are removed.

Last month, scientists were stunned by an iceberg twice the size of Hong Kong that was picked up by satellite imagery drifting towards Australia.


The whopping ice slab, nearly 87 square miles in size and weighing 200 billion tons, is already far closer to Australia than icebergs normally travel, about 1700km south-southwest of Western Australia.


Glaciologist Neal Young said he thinks the iceberg broke off the Antarctic about 10 years ago and has been slowly floating around the icy continent before embarking on its unusual route north.
However, he dismissed a link between the iceberg's journey and global warming, insisting it had nothing to do with climate change.


In December, most nations agreed at a Copenhagen climate summit to limit any rise in world temperatures to below 2 Celsius above pre-industrial times.


But they failed to set cuts in greenhouse gas emissions needed to achieve the goal.

How to Digitally Record/Video a UFO sighting:


Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:




Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
