Renewable energy sources such as solar power, wind, biomass and hydropower could meet nearly 80 per cent of the world’s energy supplies by 2050 if governments pursue policies that harness their potential, a United Nations-backed report released today says. The findings of more than 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC) indicate that if the path of renewable source is fully followed, greenhouse gas emissions could stay...

A rise in global temperatures of four degree Celsius is likely to occur during the 21st century causing "devastating impacts" if greenhouse gas emissions continue rising at the current rate, according to a group of international scientists. In a special issue of the UK journal "Philosophical Transactions of the Royal Society A" -- which coincides with the start of the United Nations climate talks in Cancun, Mexico -- scientists argue that...

Even as the Indian Network for Climate Change Assessment — dubbed “the Indian Intergovernmental Panel on Climate Change (IPCC)” — released its first report on the impact of climate change in four regions of the country, it admitted that significant research gaps and lack of extensive databases were hampering Indian climate science. Long-term localised data was not available on vegetation and forest cover, socio-economic trends, farm inputs, pests and crop diseases,...

An international committee reviewing the "processes and procedures" of the UN's climate science panel is set to report on Monday. The Intergovernmental Panel on Climate Change (IPCC) has faced mounting pressure over errors in its last major assessment of climate science in 2007. The review was overseen by the Inter-Academy Council, which brings together bodies such as the UK's Royal Society. The findings are to be unveiled at a news conference in New...

In some remote villages in India, which are most unlikely to pose as models of development, a quiet rejuvenation is taking place, with communities learning to adapt to the climate change reality of the country today. Everyone knows by now that one of the foremost signs of climate change for the country is the changing pattern of the monsoon. The Intergovernmental Panel on Climate Change (IPCC) has already forecast shorter yet...
