Climate change is now officially a human rights issue. The un Human Rights Council on March 28 endorsed a resolution recognizing that global warming threatens the livelihoods and welfare of many of

Rick Wagoner, General Motors' president and chief executive, has dismissed United Nations research that links biofuel production to rising food prices as "shockingly misinformed". The blunt assessment by the head of the world's largest car company reinvigorates intense debate about ostensible social costs and environmental benefits of biofuels, a burgeoning industry some analysts say crowds out food production. "If you look at what's causing higher [bio]fuel prices, the cost of corn is a very small part of that," Mr Wagoner said at the Auto China show in Beijing yesterday.

Urgent action to help the world's poorest farmers help themselves would make a significant contribution to tackling the global food crisis in a single growing season, according to Jeffrey Sachs, United Nations development adviser. "In much of the poorest parts of the world, the potential for significant increases in food production is very real," said Mr Sachs, director of the Earth Institute at Columbia University and adviser to Ban Ki-moon, the UN secretary-general.

He watches men converting rain forest into cattle pastures and soybean fields with bulldozers and chains. He sees fires wiping out such gigantic swaths of jungle that scientists now debate the "savannization" of the Amazon.

Rising food prices across the world are generating a great deal of heat and dust. Some of that high-decibel debate about food versus fuel and end of an era when food prices were declining, has found its way into India as well.

Italy will achieve its greenhouse gas-cutting targets under the Kyoto protocol by buying carbon credits from Russia, under a deal announced yesterday that could cost the government billions of euros. Italy is expected to miss its Kyoto targets by a total of about 400m to 500m tonnes of carbon dioxide, and will therefore have to make up the shortfall with carbon credits issued by the United Nations. But the government did not say how many credits it would buy under a deal with Carbon Trade and Finance, a joint venture between Russia's Gazprombank and Dresdner Bank.
