Areas where food supplies could be worst hit by climate change have been identified in a report. Some areas in the tropics face famine because of failing food production, an international research group says. The Climate Change, Agriculture and Food Security (CCAFS) predicts large parts of South Asia and sub-Saharan Africa will be worst affected. Its report points out that hundreds of millions of people in these regions are already experiencing a food...

A comprehensive study of Isro satellite images reveals 75% of Himalayan glaciers are on the retreat, with the average shrinkage being 3.75km during the 15 years under study. The grim findings come after raging controversy over claims in the 2007 IPCC report of Himalayan glaciers disappearing by 2035, which were later retracted. The project, which studied 2,190 glaciers, was commissioned by the ministry of environment and forests and department of space...

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...

The United Nations Food and Agriculture Organization (FAO) has initiated a programme to improve global information on greenhouse gas emissions from agriculture and accurately assess farming’s potential to mitigate global warming. The improved data acquired by the FAO Mitigation of Climate Change in Agriculture (MICCA) programme, which will receive $5 million in funding from Germany and Norway, will be made available via an online global knowledge base that will profile greenhouse...

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...
