The number of Adélie penguins living in East Antarctica may be double what scientists previously thought. New data collected by researchers at the University of Adelaide in Australia estimates the population number at nearly six million—almost four million higher than previous estimates.
Tracking penguin populations in Antarctica is a critical component of understanding environmental changes in the region.Now, thanks to a collaboration between NASA and Stony Brook University, citizen scientists can lend a hand through the use of a new, interactive, and user-friendly website that tracks Antarctic penguin populations and provides information to scientists.
A forty year study on a remote Antarctic island shows that while populations of two penguin species are declining, a third is increasing. Analysis of census data from Signy Island in the South Orkney Islands reveals that, between 1978 and 2016, the number of chinstrap penguin pairs declined by nearly 70 per cent. Pairs of Adélie penguins dropped by more than 40 per cent but the number of gentoo penguin pairs more than trebled.
Two species of sub-Antarctic penguin have surprised scientists in New Zealand by travelling up to 15,000km (9,320 miles) during six months spent at sea.
The new study, published in the journal Scientific Reports on Wednesday, looked at various levels of warming expected over this century as predicted by the Intergovernmental Panel on Climate Change, the United Nations’ group that is the gold standard for climate forecasts.
A colony of Adelie penguins faces being wiped out after an iceberg the size of Rome became lodged in their bay.

A study of how climate change has affected emperor penguins over the last 30,000 yrs found that only 3 populations may have survived during the last ice age, and that the Ross Sea in Antarctica was likely the refuge for one of these populations.
In a part of the world that is experiencing the most dramatic increase in temperature and climate change, two very similar species of animals are responding very differently.
The most complete audit ever assembled of Antarctic sea life is to be published this week.
The first global census of the Adélie penguin, long considered a key indicator species to monitor and understand the effects of climate change and fishing in the Southern Ocean, has revealed its population (3.79 million breeding pairs) to be 53 percent larger than previously estimated.
A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins.
An international team of scientists studying Emperor penguin populations across Antarctica finds the iconic animals in danger of dramatic declines by the end of the century due to climate change.
