Workshop on climatic change

LUCKNOW, DEC. 2. The earth's climate has changed throughout its geological history yet humanity was concerned about climatic variations on a day-to-day basis.

This was stated by Member-Secretary, Department of Science and Technology (DST), Government of India, New Delhi Dr P Sanjeeva Rao during the three-day workshop on `Weather and Climate Change' which began at the Birbal Sahni Institute of Palaeobotany (BSIP) here yesterday.

Dr Rao said the humanity was concerned about climatic variations as there was perceptible change in the weather conditions on day-to-day, monthly and seasonal basis. ``The quality of air we breathe, agricultural produce we feed upon and devastating cyclones which we experience in our day-to-day life are closely associated with the climate system,'' he said.

``For source planning, it is of great importance if we are able to understand and anticipate the course of climate we are going to face. Weather records using land-based and ocean-based instruments and space-based satellites are taken to refine the weather forecast and climate prediction at hourly to daily basis and seasonal to annual and longer time scales,'' he added.

During his presentation, Dr Rao informed about the projects being assisted by the DST in several institutions and organisations in the country regarding studies on climate change.

He said the Arabian Sea Monsoon Experiment (ARMEX), one of the recent and largest experiment underway is being carried out by 25 organisations and over 500 scientists who are studying various climatic aspects of the Arabian Sea.

He said during the experiments it was found that the convective systems over the Arabian Sea led to intense rainfall over the west coast. Besides, very low black carbon content was found in the sea as compared to the neighbouring regions of the country.

A number of other programmes of climatic variability and effect of weather on crop productivity, commercial production of cut flowers in the humid tropics and monsoon systems in different parts of the country were also taken up by various institutions, he added.
