Some Asian glaciers 'putting on mass'

The Karakoram range is home to K2,
the world's second highest mountain

Some glaciers on Asia's Karakoram mountains are defying the global trend and getting thicker, say researchers.

A French team used satellite data to show that glaciers in part of the Karakoram range, to the west of the Himalayan region, are putting on mass.

The reason is unclear, as glaciers in other parts of the Himalayas are losing mass - which also is the global trend.

The region's glaciers are poorly studied, yet provide a vital water source for more than a billion people.

The response of Himalayan glaciers to global warming has been a hot topic ever since the 2007 report of the Intergovernmental Panel on Climate Change (IPCC), which contained the erroneous claim that ice from most of the region could disappear by 2035.

Although often regarded as part of the Himalayas, the Karakoram range is technically a separate chain that includes K2, the world's second-highest peak.

Much of the region is inaccessible, and there has been a general recognition that observations need to be stepped up in order to clarify what is going on.

The French scientists, from the National Centre for Scientific Research and the University of Grenoble, compared two models of land surface elevation derived from satellite observations, for 1999 and 2008, and report their findings in the Nature Geoscience journal.

The method has been used before in other mountain ranges, but it is not as straightforward as it might sound.

"It's not been used more because these elevation models are quite difficult to acquire - you need clear sky conditions and reduced snow cover," said lead researcher Julie Gardelle.

Other factors that can change the height of the ice surface, other than changes to the ice itself, also need to be accounted for.

Having done all these calculations, the team found that between 1999 and 2008 the mass of the glaciers in this 5,615 sq km (2,168 sq miles) region of the Karakoram increased marginally, although there were wide variations between individual glaciers.

Foggy picture

Why this should be is not clear, though it is well known from studies in other parts of the world that climate change can cause extra precipitation into cold regions which, if they are cold enough, gets added to the existing mass of ice.  

Some data came from the Satellite
 pour l'Observation de la Terre (Spots)
mission

"We don't really know the reason," Ms Gardelle told BBC News.

"Right now we believe that it could be due to a very specific regional climate over Karakoram because there have been meteorological measurements showing increased winter precipitation; but that's just a guess at this stage."

Whatever the region, it is clear that the trend contrasts with other parts of the wider Himalayas-Hindu Kush region, home to an estimated 210 million people and where glaciers act as fresh water stores for about 1.3 billion living in river basins below.

Late last year, the Kathmandu-based International Centre for Integrated Mountain Development (Icimod) released data showing that across 10 regularly studied glaciers, the rate of ice loss had doubled since the 1980s.

However, it also made clear just how sparse data is from the region, finding only these 10 intensively studied glaciers among a total of more than 54,000.

Measurements by the GRACE satellite mission, which detects minuscule variations in the Earth's gravitational pull, have also shown a net loss of mass across the whole region.

Graham Cogley, the scientist from Trent University in Ontario, Canada, who first publicly questioned the IPCC's 2035 figure, comments in Nature that reconciling the different mass loss figures found by different methods of study "will keep glaciologists busy for some time".

GLOBAL WARMING – NOT LONG TERM (WATER CYCLE)

New Mini Ice Age

"The weather you have today, and all the alarming attributes of it, is a scenario of what was scheduled to happen on Earth anyway. I review again that the weather changes you are seeing prophesied by myself, 21 years ago, are not a surprise. The changes are not caused by the pollutants you put in the air. You call it global warming and that's a nice phrase, and perhaps that will get you to put less pollutants in the air – a very good thing. But what you are seeing in the weather shift today was not caused by Humans putting things into the air. It would have happened anyway in about 300 years."

"We've called this process the water cycle, since it's all about water, not about air. The water is the predominant attribute of Gaia and of the weather cycle you're seeing. More predominant is the temperature of it. The cycle is ice to water and water to ice, and has been repeated on this planet over and over and over. It is not new. It is not exceptional. It is not frightening. But it's a cycle that modern humanity has not seen before, and it's a long cycle that is beyond the life span of a Human Being. Therefore, it tends to be overlooked or not seen at all !"

"In the days of the Lemurians, the water level of the Pacific Ocean was almost 400 feet lower, and that's only 50,000 years ago. [Kryon invites science to check this out – the water level at that time.] That was a water cycle working, and the reason it was lower was due to so much of the water being stored as ice. Today you're going through another water cycle that will eventually lead to cooling. The last one was in the 1400s."

"Science sees that at about 1650. As mentioned, they are so slow there is no remembrance that a Human has of them except in past writings and in the rings of the trees. The time span of the changes is so great that environmental record keeping does not exist in the form that it does today. But you can still look at the rings of the trees and at the striations of the rocks and can generally figure out that a few hundred years ago, you had a mini-ice age. Now you're going to have another one."  Read more .....(THE RELATIONSHIP TO GAIA - April 2010 (Kryon Channeling))
