Spewing summit The Copenhagen summit will generate more carbon emissions than any previous climate conference, equivalent to the annual output by 2,300 Americans or 660,000 Ethiopians. Delegates, journalists, activists and observers from almost 200 countries have gathered at the December 7-18 summit and their travel and work will create 46,200 tonnes of CO2, most of it from their flights to Copenhagen. This would fill nearly 10,000 Olympic swimming pools. The calculation includes...

As one of its first steps towards reducing its greenhouse gas footprint, the United Nations – after one of the most wide-ranging and painstaking exercises in its history – announced today that it emits 1.7 million tons of carbon dioxide annually worldwide. That amount, more than half of which is generated by peacekeeping operations, represents just 3.3 per cent of emissions generated by New York City, the host city of...

The walkout by the developing countries followed an exchange between Australian and African delegates at a meeting called to set emission reduction targets for the industrialised countries.

A certain amount of irreverence is essential for creative pursuit in science.’ The first grand challenge before Indian science is that of building some irreverence. Our...

Many attribute high levels of objectivity and integrity to scientists, which is not true of many of them. Scientists have been known to manipulate results to their advantage. Scientific issues are often complex, there are differing views among scientists and the layman finds it difficult to decide which scientific course is harmful or beneficial....
