Tyrannosaurus Rex Found in Canada is World's Biggest

A team of paleontologists said that the towering Tyrannosaurus rex discovered in western Canada in 1991 is the world's biggest, following a decades-long process of reconstructing its skeleton.
Nicknamed Scotty for a celebratory bottle of scotch consumed the night it was discovered, the T. rex was 13 meters (yards) long and probably weighed more than 8,800 kg (19,400 pounds), making it bigger than all other carnivorous dinosaurs.

Global Ocean is Absorbing More Carbon

The global ocean absorbed 34 billion metric tonnes of carbon from the burning of fossil fuels from 1994 to 2007, a four-fold increase to 2.6 billion metric tonnes per year when compared to the period starting from the Industrial Revolution in 1800 to 1994.
A new research finds carbon dioxide emissions have increased in the atmosphere, the ocean has absorbed a greater volume of emissions.
Though the volume of carbon dioxide going into the ocean is increasing, the percentage of emissions, about 31 per cent, absorbed by it has remained relatively stable when compared to the first survey of carbon in the global ocean published in 2004.

A Climate Vulnerability Index for India

The Department of Science and Technology (DST) will be commissioning a study to assess the climate risks faced by States in India.
This follows an assessment of the global warming risks faced by 12 Himalayan States, and discussed at last year's U.N. climate change conference in Poland, that found States such as Assam, Arunachal Pradesh and Uttarakhand vulnerable to climate change.
Last year the Indian Institutes of Technology (IIT) at Mandi and Guwahati, and the Indian Institute of Science (IISc), Bengaluru, coordinated with State authorities in Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Arunachal Pradesh, Sikkim, the hill districts of West Bengal, Himachal Pradesh, Uttarakhand and Jammu and Kashmir, to evolve a common methodology, and determine how districts there are equipped to deal with the vagaries of climate change.

Wood Snake Rediscovered

A species of wood snake that wasn't seen for 140 years has resurfaced in a survey conducted by scientists in the Meghamalai Wildlife Sanctuary.
The species, endemic to the Meghamalai forests and the Periyar Tiger Reserve landscape, was recently rediscovered by R. Chaitanya, a herpetologist, and Varad Giri, director, Foundation for Biodiversity Conservation.
The local population of wood snakes was last spotted and recorded by British military officer and naturalist Colonel Richard Henry Beddome in 1878.

Greenland Ice Sheet Melting Even in Winter

A new study has found that rain is becoming more frequent in Greenland and accelerating the melting of its ice.
Scientists are surprised to discover rain falling even during the long Arctic winter.
The massive Greenland ice-sheet is being watched closely because it holds a huge store of frozen water.
And if all of that ice melted, the sea level would rise by seven metres, threatening coastal population centres around the world.
