Since late 2019, East Africa and the Middle East have been experiencing their worst locust outbreaks in decades. A small locust swarm can eat more food than 35,000 people; but some locust swarms in the area have grown to over two thousand times that size. And it’s all coming right on the heels of a season of catastrophic flooding in the region.
But that isn’t a coincidence: The desert locust thrives when dry weather turns wet. And in 2018 and 2019, a series of freak weather events brought record-setting rainfall to the Middle East and East Africa. The result of all this is a region at risk of a famine, in the middle of a pandemic. And because freak weather is a hallmark of climate change, it’s also the kind of thing we can expect to happen again.
