SCIENTISTS from the University of Michigan in the US have discovered that stony lumps of calcium carbonate, known as otoliths, found in the ears of most fishes, can offer clues to seasonal

A tussle over funding clouds issues of climate change a biodiversity.

Environmental space may be defined as the total quantity of natural resources that can be used on a sustainable basis, for example, the total quantity of carbon dioxide that can be released into the

Getting scientists from developing countries to serve on the climate change panel is proving difficult.

Little was achived at the December climate meeting in Geneva by way of setting schedules for future sessions,mainly because of stalling tactics by OPEC countries.

A bill introduced during the last session of Parliament seeks to change the definition of death from when the heart stops beating to when the brain ceases to function. The bill will benefit patients awaiting organ transplants and who have to depend on the

The average height of the Himalay has been going down over the last two million years because of climatic changes, surveys indicate.

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. The tropical regions of the biosphere are the most biogeochemically active coastal regions and represent potentially important sinks of C in the biosphere.

Observations made during the 1987 El Niño show that in the upper range of sea surface temperatures, the greenhouse effect increases with surface temperature at a rate which exceeds the rate at which radiation is being emitted from the surface. In response to this 'super greenhouse effect', highly reflective cirrus clouds are produced which act like a
thermostat, shielding the ocean from solar radiation. The regulatory effect of these cirrus clouds may limit sea surface temperatures to less than 305 K.

The UN sponsored discussions to prepare a global convention on climate began in February in USA. The aim is to prepare a legally binding convention to curb gaseous emissions leading to a much feared climate destabilisation. This convention is being seen as the world's greatest commitment to the environment and its future generations.
