Major Portions of 10 Lakshadweep Islands Might go under Water

A study conducted by ocean engineering scientists at IIT-Kharagpur shows that 10 islands among the 36 islands of Lakshadweep archipelago might have more than 60 per cent land loss in the next 30 years because of the continuous and extreme rise of sea water level in the last 15 years.
The study was conducted on the ten most vulnerable islands of the archipelago and shows that there will be 70 per cent to 80 per cent land loss in eight of the ten islands by 2035. The other two islands will also have a land loss close to 40 per cent.

New Type of Ancient Human Discovered in Israel

Researchers working in Israel have identified a previously unknown type of ancient human that lived alongside our species more than 100,000 years ago.
They believe that the remains uncovered near the city of Ramla represent one of the "last survivors" of a very ancient human group.
The finds consist of a partial skull and jaw from an individual who lived between 140,000 and 120,000 years ago.
The team members think the individual descended from an earlier species that may have spread out of the region hundreds of thousands of years ago and given rise to Neanderthals in Europe and their equivalents in Asia.

Glacier Melt in Himalayas to Increase Rapidly Till 2050

Snow and glaciers are melting rapidly in the Himalayan range due to climate change, altering water supplies in the rivers like Indus, Ganga and Brahmaputra that flow through the Himalaya-Karakoram (HK) ranges.
According to a study, "Glacio-hydrology of the Himalaya-Karakoram," undertaken at the Indian Institute of Technology, Indore, total river runoff, glacier melt, and seasonality of flow in these rivers are projected to increase until the 2050s, with some exceptions and thereafter is expected to decrease.
The HK region in South Asia, often called the water tower of Asia or the Third Pole is one of the most heavily glacierised mountain regions on Earth and understanding the response of HK rivers to climate change is crucial for almost a billion people who depend on these water resources.
