Sri Lanka will be among 18 countries around the Indian Ocean Rim which will participate in an ocean-wide tsunami exercise on October 14 to coincide with World Disaster Reduction Day.

This report is the result of the effort to highlight the use of scientific and technical knowledge as an essential foundation for disaster risk reduction, and to make recommendations on key issues and priorities, including ways that specialist scientific and technical information can be more effectively adopted and put into practice.

Endangered lemur species found only in Madagascar are being slaughtered and served up in local restaurants as poachers take advantage of a security vacuum on the island after a coup earlier this year.

Ice cores extracted from the Antarctic ice sheet suggest that glacial conditions and the relationship between temperatures and atmospheric carbon dioxide concentrations have been constant over the last 800,000 years, but there is some evidence for a fluctuating severity of glacial periods mediated by previously unidentified mechanisms.

At times in the past, mobile ocean fronts in the subtropics have exercised an influence on the magnitude of climate change by decoupling temperature from levels of carbon dioxide in the atmosphere.

This document reviews and synthesises the science of climate change since the publication of the IPCC

To take on MNC dominance in new-generation molecules.

The conventional anti-lepidopteran formulations sell for Rs 500-600 a litre (Rs 250-300 an acre), whereas Syngenta

With their focus on greenhouse gases, atmospheric scientists have largely overlooked lowly soot particles. But black carbon is now a hot topic among researchers and politicians. Jeff Tollefson investigates.

"The trends in disasters, particularly from climate change, are of enormous concern," said John Holmes, U.N. undersecretary-general for humanitarian affairs.

"We can only expect that this kind of trend is going to continue," he told a news conference.
