Natural disasters have increased due to rise in earth's temperature and climate change. According to Centre for Science and Environment(CSE), cyclone Nargis is not only a natural disaster but because of climate change it has become a man-made disaster.

Pointing fingers at climate change to be the likely cause of the cyclone Nargis, which killed nearly 22,000 people in Burma, the Centre for Science and Environment (CSE) has cautioned nations to speed up the curtailing of the emission of greenhouse gases.

Environmentalists have warned that tropical cyclone Nargis, which has left more than 20,000 persons dead and 40,000 missing and thousands homeless, is not just a natural disaster but a man-made disaster because of climate change. Nargis, the green brigade says, happened because "the rich have failed to contain greenhouse gas emissions necessary for their growth'.

India's concerns relating to grains, in general, and wheat, in particular, are becoming more serious. While demand continues to expand rapidly, output has turned unsteady in the last six or seven years, as much because of water stress and declining soil health as the effects of global warming. Wheat prices have doubled from what they were in early 2007. G. Chandrashekhar

Global warming is likely to imperil tropical species much more than fauna in the Arctic regions, even with a slight rise in temperature. "Many tropical species can only tolerate a narrow range of temperatures, as the climate they experience is pretty constant throughout the year,' said Curtis Deutsch of the University of California and co-author of a new study. "Our calculations show that they will be harmed by rising temperatures more than would species in cold climates. Unfortunately, the tropics also hold the large majority of species on the planet,' he said.
