The KGP Chronicle (July 8, 2021)

IIT Kharagpur researchers revealed significant increase of ozone pollution in the Antarctic troposphere for the past 25 years, which is a concern as the region is far from the industries and continental emission sources.

A recent scientific study analysed the significant increase of Surface Ozone and Tropospheric Ozone in Antarctica for the past 25 years. The research findings were supported by surface-based and ozonesonde measurements in Antarctica.

“The increasing trend in ozone pollution across Antarctica would have a profound impact on the future climate of one of the most climate-sensitive regions on the Earth, as tropospheric ozone has warming feedback to the Earth’s climate, and that can accelerate melting of sea-ice, changes in water masses, and damages to the ecosystem”, said Prof Jayanarayanan Kuttippurath, the lead researcher and Assistant Professor of Centre for Oceans, Rivers, Atmosphere, and Land sciences at IIT Kharagpur.

 The research findings are published in Environmental Science and Technology Journal of the American Chemical Society (https://doi.org/10.1021/acs.est.0c08491) on June 16, 2021. In this regards, American Chemical Society made the press release on the same date (https://www.acs.org/content/acs/en/pressroom/presspacs/2021/acs-presspac-june-16-2021/ozone-pollution-has-increased-in-antartica.html).
