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...

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...

Charged particles from beyond solar system possibly affect the pace, but the extent is not clear The role of the cosmic rays has been highlightedin a paper by the former ISRO Chairman, U.R. Rao Dr. Rao points to a nine per cent reduction in the intensity of cosmic rays during the past 150 years The impact of cosmic rays on global warming needs to be assessed. Are charged particles coming from beyond the...

The environment ministry today released a paper by a senior Indian space scientist that highlights the role of cosmic rays in global warming and attempts to rekindle a 13-year debate on natural factors heating the planet. The scientific review, by Udupi Ramachandra Rao, a cosmic ray physicist and former head of the Indian Space Research Organisation (Isro), also claims the UN climate change agency overestimated the role of greenhouse gases on...
