Atmospheric aerosols can reduce radiation: expert

Special Correspondent


‘Aerosols can bring down global warming'

Call to adopt international climate control norms


KANNUR: Atmospheric aerosols can reduce solar radiation reaching the surface of the earth as it lengthens life span of clouds and increases reflective power overtime, according to Kalliat T. Valsaraj, Professor and Head of the Department of Chemical Engineering at the Louisiana State University.

Presenting a paper on ‘Atmospheric aerosols and its impact on climate change' at a seminar on the Mangattuparampa campus here on December 23, Dr. Valsaraj said large amount of aerosols in the atmosphere could reduce global warming.

Research works going on in the field of bio-engineering showed that spraying of sulphur aerosols could reduce global warming effectively, he said.

Dr. Valsaraj further noted that anthropogenic aerosols emitting from vehicular and industrial activities could cause respiratory disorder in human beings.

Speaking on the atmospheric problems relevant to the State, he said vehicular emissions, volatilisation of pesticides, aerosols from sea sprays and primary and secondary aerosols were causing problems in the State. He said erratic rainfall, increased ambient air pollution and soil erosion were also causing atmospheric problems to the State.

He suggested that these could be reduced by using the methods formulated by the Inter-Governmental Panel for Climate Change.

University Vice Chancellor P.K. Michael Tharakan presided over the function. Registrar K.M. Abdur Rasheed was also present.
