In June, remote sensing analyst Raj Bhagat noticed a strange signal on India’s weather radar. It looked like a small band of rain near Delhi, moving southwest, but Bhagat was convinced it was a locust swarm.
“People began to report it,” he says, referring to sightings on the ground. Giant locust swarms had spread to northern India earlier in the year, ravaging crops and destroying people’s livelihoods. “The timelines were perfectly matching.”
