Winter in the Indian capital is a season of mists, minus the mellow fruitfulness. The air becomes charged with toxic emissions and particles that cannot disperse due to a meteorological phenomenon called "atmospheric inversion". According to B.P. Yadav, scientist with the meteorological department, atmospheric inversion is caused by a warming of the upper layers of the atmosphere, trapping colder air on the surface and, with it, vehicular and industrial emissions. "The immediate...

companies could have a big impact in the fight against climate change, according to a United Nations report released today.“Waste and Climate Change: Global Trends and Strategy Framework” – prepared by the UN Environment Programme’s (UNEP) International Environmental Technology Centre – says the waste sector is particularly well placed to cut its contribution to global man-made greenhouse gas (GHG) and even become an emissions saver.The report recommends reducing the amount...

The main greenhouse gases have reached their highest concentration levels since pre-industrial times, a United Nations climate research body said today. The World Meteorological Organization’s (WMO) 2009 Greenhouse Gas Bulletin warns that carbon dioxide, methane and nitrous oxide have all increased their presence, increasing their burden on the earth’s atmosphere. “Greenhouse gas concentrations have reached record levels despite the economic slowdown. They would have been even higher without the international action taken...

Complexity and unsolved problems are at the very heart of the sustainability challenge, and at the very heart of M.S. Swaminathan's thinking and essays. In 1798, Thomas Robert Malthus offered the piercing insight that geometric population growth would inevitably outstrip food production, leaving society destitute and hungry. Since that time, our optimism of beating the “Malthusian curse” has waxed and waned. Few people in modern history have done more to help...

For your sake, and earth’s sake, have fish instead of mutton. If you are truly climate-friendly, go bananas. According to a study that analysed greenhouse gas emissions associated with a set of common Indian food items, fish is a superior alternative to mutton, not just for humans but also for the planet’s health, while bananas are the most climate-friendly. The study, by scientists at the Indian Agricultural Research Institute (IARI), New Delhi,...
