Shrinking glaciers leading to increase in population of Adelie penguins

Researchers of University of Tasmania in Australia have discovered that shrinking glaciers are leading to the birth of more Adelie penguins in the East Antarctica region. As per their findings, in the last 14,000 years, the population of Adelie penguins has increased nearly 135-fold because, additional breeding sites have become exposed due to the retreating glaciers.
This has been reported in zeenews.com dated 18 November 2015.

It can be assumed that this population explosion can be attributed to current environmental conditions are more favorable for Adelie penguins than they were when compared to the last ice age.
Shrinking glaciers could be a key driver of population change over millennia for Adelie penguins in East Antarctica. While studying the response of thee bids to past climate change it would be possible to predict how well Adelie penguins will respond in the future.
Till now, research had concentrated on short-term changes in terms of years or decades, but the climate change that is happening right now is likely to have effects over thousands of years.
East Antarctica is, at present, home to 30 percent of the global population of Adelie penguins, with an estimated abundance of 1.14 million breeding pairs.

Rise in ocean levels much faster than anticipated – danger signs for US East Coast

#OceanLevels #globalwarming #ClimateChange #glaciermelting It is a fact that global warming and melting of Antarctica icecaps has resulted in the rising levels of oceans and, as per statistics, the world's oceans are now rising far faster than they did in the past because of climate change.
A new study has brought out the hard facts that for much of the 20th century - until about 1990 - sea level was about 30 percent less than earlier research had figured. However, about 25 years ago the rise in the levels was comparatively faster and the acceleration in 1990 was more dramatic than had been imagined or calculated.
As revealed in the journal Nature the present sea level rise rate that began in 1990 is calculated to be 2.5 times faster than it was from 1900 to 1990 – these are matters of grave concern.
Previous research had revealed that between 1900 and 1990, the seas rose about 2cm a decade while, the rise during 1900-1990 was less than 1.3cm every decade.
In the opinion of scientists, such a fast pace can be attributed to the melting ice sheets in Greenland and West Antarctica apart from shrinking glaciers that have been triggered by man-made global warming.
Lead author of the study Carling Hay, a geophysical researcher at Harvard University, feels that this trend is not good news for the cities along the US East Coast where water levels are rising at a much faster rate than the world average.
