Rare triple-dip La Nina behind unusual AQ trend in India in 2022-23: Study

An unprecedented triple-dip La-Nina event, extended by climate change, triggered a peculiar trend in the 2022-23 winter season where air quality improved in north India while peninsular India recorded an increase in pollution levels, according to a new study released on Sunday. The three consecutive years of La Nia conditions (2020-23) - a rare triple-dip phenomenon - had widespread impacts on the ocean and climate across the globe. The study by a team of scientists led by Gufran Beig, Chair Professor, National Institute of Advanced Studies, emphasised that besides local emissions, rapidly changing climate is a significant factor affecting air quality. Published in the Elsevier Journal, the study reveals that the air quality worsened in peninsular Indian cities in the 2022-23 winter season but improved in the northern part of India, contrary to the trends seen in recent decades. Among the north Indian cities, Ghaziabad registered the most significant improvement with a reduction of

Cases of respiratory issues, eye irritation rise in Delhi hospitals

Though Delhi recorded a brief improvement in air quality last week, city hospitals continue to report a rise in the number of patients visiting hospitals for respiratory issues, prolonged coughing, throat infections and eye irritation. The national capital experienced 'very poor' to 'severe' air quality for two weeks starting October 28 with a suffocating haze lingering over the city during the period.
