The Pine Island Glacier in West Antarctica, which is around twice the size of Scotland, is losing ice four times as fast as it was a decade years ago.
The research, published in the journal Geophysical Research Letters, also reveals that ice thinning is now occurring much further inland. At this rate scientists estimate that the main section of the glacier will have disappeared in just 100 years, six times sooner than was previously thought.
The Pine Island Glacier is located within the most inaccessible area of Antarctica – over 1000 km from the nearest research base – and was for many years overlooked. Now, scientists have been able to track the glacier's development using continuous satellite measurements over the past 15years.
"Accelerated thinning of the Pine Island Glacier represents perhaps the greatest imbalance in the cryosphere today, and yet we would not have known about it if it weren't for a succession of satellite instruments," says Professor Andrew Shepherd, a co-author of the research from the School of Earth and Environment at the University of Leeds.
"Being able to assemble a continuous record of measurements over the past 15 years has provided us with the remarkable ability to identify both subtle and dramatic changes in ice that were previously hidden," he adds.
Scientists believe that the retreat of glaciers in this sector of Antarctica is caused by warming of the surrounding oceans, though it is too early to link such a trend to global warming.
The 5,400 km squared region of the Pine Island Glacier affected today is big enough to impact the rate at which sea level rise around the world.
"Because the Pine Island Glacier contains enough ice to almost double the IPCC's best estimate of 21st century sea level rise, the manner in which the glacier will respond to the accelerated thinning is a matter of great concern " says Professor Shepherd.
The research was led by Professor Duncan Wingham at University College London, and was funded by the UK Natural Environment Research Council.

The 2008 Research Assessment Exercise showed the University of Leeds to be the UK's eighth biggest research powerhouse. The University is one of the largest higher education institutions in the UK and a member of the Russell Group of research-intensive universities. The University's vision is to secure a place among the world's top 50 by 2015. www.leeds.ac.uk
The School of Earth and Environment at the University of Leeds is has more than 90 academic staff, over 60 research staff and 140 postgraduate researchers. It focuses on a multidisciplinary approach to understanding our environment, studying the Earth from its core to its atmosphere and examining the social and economic dimensions of sustainability. www.see.leeds.ac.uk/index.htm
The Natural Environment Research Council is the UK's main agency for funding and managing research, training and knowledge exchange in the environmental sciences. It coordinates some of the world's most exciting research projects, tackling major issues such as climate change, environmental influences on human health, and the genetic make-up of life on earth.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
