Paris: Climate change could release unexpectedly huge stores of carbon dioxide from Arctic soils, which would in turn fuel a vicious circle of global warming, a new study warned on Sunday.

And according to one commentary, current models of climate change have not taken this extra source of greenhouse gas into account. Scientists have long known that organic carbon trapped inside a blanket of frozen permafrost covering one fifth of the world's land mass would, if thawed, release greenhouse gases into the atmosphere.

Sydney: The chance discovery of the remains of a prehistoric giant kangaroo has cast doubts on the long-held view that climate change drove it and other mega-fauna to extinction, a new study reveals.

The research, published this week in the US-based journal Proceedings of the National Academy of Sciences, argues that man likely hunted to death the giant kangaroo and other very large animals on the southern island of Tasmania.

New Delhi: The effect of climate change on India could be far worse than previously estimated. Latest projections indicate that after 2050, temperatures would rise by 3-4 degrees over current levels and rainfall would become both heavier and less regular, posing a grave threat to agriculture. These are part of the research conducted by scientists at Pune's Indian Institute of Tropical Meteorology, one of the key government institutions studying climate change in India. The findings are currently under review by a well-recognized scientific journal.

Alleging that the Red Indian Horned Owl, locally known as hoodoo, is being sold to NASA for facilitating research works, People for Animals, a non-government organisation working against cruelty against animals, has decided to move Chief Minister Tarun Gogoi urging the latter to initiate measures for protection of the endangered species.

Sangeeta Goswami, president of People for Animals, Assam chapter, alleged that the endangered birds are being sold for Rs 25 lakh each in the international market, which, of late, has caught the attention of animal activists worldwide.

Washington: Climate experts have warned that the world might have already reached the tipping point of climate change, where immediate actions needed to be done to reduce the effects of global warming. According to a report in Discovery News, the scientist who first put forward this theory is Nasa climate scientist James Hansen. Though Hansen had earlier warned about the dangers of climate change in 1988, his latest theory determines that "we have used up all slack in the schedule for actions needed to defuse the global warming time bomb.'
