Traces of penguins measure Antarctic ice movement

Climate change is not new in life. Hundreds or sometimes thousands of years later, the massive ice sheets in Antarctica are raised and slipped down just like the warming and warming of the Earth.

Using the Carbon-14 chronometer, scientist Steven D.Emslie identified the age of the ancient Adelie penguin that resided there for 45,000 years, higher than any known penguin species. .

He also drew a chart of the population between birds with change, forming new ice. Finally, he accurately calculated the transfer time of the ice.

The penguin Adelie returned to the same location nesting year after year and left countless traces like bones, feathers, feces . almost everywhere. He even found a mummy whose time is approximately 100 years for this bird.

' Adelie is a small penguin, and is everywhere in Antarctica. It nests along the banks of the glaciers. The traces that the ancient bird left were intact, and it was also raised and lowered with the ice in this region. Based on that ancient trace, I discovered that the north bank of Ross Glacier was elevated 13,000 years ago, when it began to slip at the end of the ice age . ' - Emsile wrote so in the book entitled 'The 45,000-year history of Adelie penguins and the climate change in Ros Antarctica river.'

Antarctic ice plays an important role in reducing the temperature of the earth and the ocean, as the ice surfaces here reflect sunlight.

Emsile's research results were funded by the National Science Foundation, the Institute of Social Geography and NASA.
