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 its all coming right on the heels of a season of catastrophic flooding in the region.

But that isnt 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, its also the kind of thing we can expect to happen again.

One of the things that helped prime the region for locusts was an unusually strong Indian Ocean Dipole. Watch our piece about that here:

And this FAO press conference from February helped me answer a lot of the questions in this piece: is a news website that helps you cut through the noise and understand what's really driving the events in the headlines. Check out
