In 2006, Nicholas Stern former chief economist, World Bank and advisor to the UK government, wrote about the economic threat from climate change in the Stern Report. He veers round to an uneasy

so far climate change study models have ignored how carbon emissions contributed to the melting of glaciers. This was not part of climate study models since reliable data on soot emissions was

us President George W Bush has announced a climate meeting for the end of September. The announcement comes at a time when there is already a un-led initiative to hammer out an agreement on

Climate change is the defining human development challenge of the 21st Century. Failure to respond to that challenge will stall and then reverse international efforts to reduce poverty. The poorest countries and most vulnerable citizens will suffer the earliest and most damaging setbacks, even though they have contributed least to the problem.

A P MITRA (1927-2007) In the early 1990s, the US Environmental Protection Agency had come out with a report incriminating Indian rice fields of emitting 38.6 million tonnes of methane per year and

conventional scientific wisdom has it that irrigation works against global warming. But there is evidence now to shake us out of complacency. Scientists from the University of California, Merced,

Data from the satellite-based Special Sensor Microwave Imager (SSM/I) show that the total atmospheric moisture content over oceans has increased by 0.41 kg/m2 per decade since 1988. Results from current climate models indicate that water vapor increases of this magnitude cannot be explained by climate noise alone. In a formal detection and attribution analysis using the pooled results from 22 different climate models, the simulated “fingerprint” pattern of anthropogenically caused changes in water vapor is identifiable with high statistical confidence in the SSM/I data.

The forecast just seems to get gloomier. Climate change may dramatically increase the risk of flooding across the globe, even far from shorelines, say scientists in the journal Nature. The reason: plants won't soak up as much moisture in a world with more greenhouse pollution.

India sent its first team to the Arctic recently. Two of its members have returned with a variety of samples, some dating back to millions of years. ARCHITA BHATTA spoke with them "We found round

Atmospheric scientist V Ramanathan fromthe Scripps Research Institute, California, USA, says brown clouds heat up the lower atmosphere. He explains to Archita Bhatta how the media misinterpreted
