A study suggests water towers of Asia contain less water than estimated.

The Himalayas are often called the water towers of Asia because of the vast amount of water locked in the form of ice in thousands of glaciers there. But concerns relating to climate change have often put a question mark on future water availability from these glaciers. Now a new study on ice thickness of glaciers has estimated that glaciers in the Hindu Kush Himalayas might contain 27 percent less ice than previously suggested.

Researchers find signatures of past climate change on the west coast.

A team of researchers have unravelled the imprints of sea level fluctuations and climate change that may have occurred along the coastal river of Saurashtra region in India’s west coast over the past 1.5 lakh years. 

Researchers analysed samples taken from more than six metres sedimentary sequences along the Noli river between Mangrol to Chorwad. They carried out geomorphology, sedimentology and optical dating studies. They found that there were four distinct significant layers.
