As dust storms brew, India breathes toxic air throughout the yearÂ

1. As dust storms brew, India breathes toxic air throughout the year In 2018 alone, there have been 50 severe storms across 16 Indian states that have led to more than 500 deaths, compared to 22 storms between 2003 and 2017.

2. Deadly dust storms sweeping over the densely-populated north Indian plains are part of a "new normal" of disruptive weather events worsening the country’s already-lethal air pollution and causing disruption in the $2.3-trillion economy. In recent months, dust clouds and storms have killed hundreds of people, destroyed thousands of homes and farmers’ crops and led to flight cancellations. The government in New Delhi, a city of more than 20 million people, ordered a halt to construction activities as the airborne sand significantly worsened north India’s air quality, far outside the winter months that usually herald the region’s descent into a months-long toxic haze. "It’s definitely a new normal -- the frequency and intensity of these storms is unprecedented," said Sunita Narain, director general of New Delhi’s Centre for Science and Environment, who added that recent weather is related to desertification, deforestation and an over-extraction of groundwater. In India, extreme weather events can quickly lead to dozens of deaths and cause economic hardship, with the World Bank estimating that environmental degradation costs India roughly $80 billion each year. At the same time, soaring levels of tiny, deadly particulate matter have prompted concern about a brewing public health emergency in the politically-gridlocked capital, where doctors warn of rising lung cancer and heart disease cases. Economic Threat In 2018 alone, there have been 50 severe storms across 16 Indian states that have led to more than 500 deaths, compared to 22 storms between 2003 and 2017, and only nine between 1980 and 2003, the CSE said. Nearly 5,000 houses collapsed, while livestock were killed and crops were ruined across the states of Uttar Pradesh, Madhya Pradesh, Bihar and others, according to a report by the CSE. Flights were cancelled across north India on airlines including Air India, Indigo and Spice Jet, said Kapil Sabharwal, a spokesman for New Delhi’s airport.
