Based on predictions of sea ice extent from climate change models, the penguins are likely to see their numbers plummet by 95% by 2100.
Climate researchers say this decrease in sea ice a symptom of a warming climate, caused largely by the combustion of carbon-rich fossil fuels.

It says this methane could be released into the atmosphere as ice retreats, contributing to climate warming.
For example, people playing next to the ocean can collect sea-dwelling creatures while those living in a snowy climate can get ice-creatures.
For instance, sea ice is predicted to increasingly shrink as a result of climate change: the late-summer Arctic sea ice may vanish almost entirely by the middle of the century, triggering unprecedented maritime challenges, with an increase in shipping and oil and gas exploration in high-latitude waters previously covered in ice.
Arctic ice helps regulate and temper the climate in many other parts of the world.
CNN: Polar bears resort to cannibalism as Arctic ice shrinks
We worry how long the ice caps have left because of climate change.
The scientists are concerned that the biosphere has seen dramatic changes since the last Ice Age, factoring in the climate and a huge increase in global population.
Faced with melting polar ice caps and worsening droughts, climate experts at a massive U.N. conference in Bali, Indonesia, urged quick action toward a new international pact that seeks to stem an increasingly destructive rise in world temperatures.
Paul Holland of the British Antarctic Survey (BAS) stuck to his findings last year that a shift in winds linked to climate change was blowing ice away from the coast, allowing exposed water in some areas to freeze and make yet more ice.
Ann Daniels from Whimple and Pen Hadow from Dartmoor will be studying the Arctic sea ice to help scientists understand more about climate change.
Hal Caswell of the Woods Hole Oceanographic Institute and his colleagues used projections of sea ice coverage from the Intergovernmental Panel on Climate Change's (IPCC) last report.
If the climate stabilises soon, the ice cap might resettle at a slightly lower mass than it has now, raising sea levels by only a few centimetres.
The team also hopes to take samples of mud from the bottom of the lake, to better understand the geological history of the West Antarctic Ice Sheet and Earth's past climate.
MSN: Mission to drill into buried Antarctic lake hits a snag
The disappearance of the ice in the past decade is astounding, climate scientists say.
The period leading up to the domestication of cereals was one of erratic climate change, as the last ice age ended.
The U.S. says that shrinking Arctic ice habitat, a product of a warming climate, puts polar bear populations in a precarious position.
Sometimes extra dry ice is added when shipping to a warm climate.
Some climate change naysayers point to Antarctic ice on the rise, as if that makes up for melting ice in the Arctic Circle.
FORBES: On Romney's 'Rising Oceans', Time To Get A Bigger Boat
Climate change models of Arctic sea ice cover in September, the month when ice is usually at its minimum, suggest an average loss of 2.5 percent of ice cover per decade from 1953 to 2003.
One tricky question is whether the overall accelerated melting of the ice sheets can be linked to man-made climate change.
"Sea ice around Antarctica is increasing despite the warming global climate, " said the study's lead author Richard Bintanja, from the KNMI.
Information on Arctic Ice research can be found at The International Arctic Climate System Study, a global consortium of polar scientists.
This makes Lake Vostok a place of great scientific interest, because the ice sheet above the lake provides the longest uninterrupted climate record known to exist.
Climate change is expanding Antarctica's sea ice, according to a scientific study in the journal Nature Geoscience.
The 2007 U.N. report, published by the Intergovernmental Panel on Climate Change, suggested that similar amounts of ice were being lost at both the polar regions.
"Such a loss of Arctic sea ice has recently been assessed to set in motion powerful climate feedbacks which will have an impact far beyond the Arctic itself, " Sommerkorn said.
Esa member-states considered its polar ice measurements to be so important to the assessment of climate change that they approved the construction of a facsimile spacecraft within months of the accident.
About 14 million years ago, a period of climate change caused the formation of the Antarctic ice sheet, which averages one mile in thickness and gets up to three miles thick in some parts.
