Worst frost in two decades across Brazil. These recent weather phenomena are rapidly intensifying and threaten further food inflation already at decade highs.
We documented last week Brazil had some of the worst frost conditions in two decades. Temperatures dropped below zero and delivered a massive blow to farmers across the country's coffee belt. The result has been sky-high coffee prices.
Back-to-back heatwaves continue to scorch the Earth across the Western half of the U.S. The corn belt, which spans the Midwest, lacks rainfall, and hot weather could negatively impact crop development, leading to an underwhelming harvest.
In Europe, China, Turkey, and India, devastating floods have torn apart towns, damaged farmland, and killed hundreds of people. Torrential rains have the risk of sparking fungal diseases for grain crops.
"All of these events are touched by jet streams, strong and narrow bands of westerly winds blowing above the Earth's surface. The currents are generated when cold air from the poles clashes against hot air from the tropics, creating storms and other phenomena such as rain and drought," Bloomberg said.
"Jet streams are the weather—they create it, and they steer it," said Jennifer Francis, a senior scientist at the Woodwell Climate Research Center. "Sometimes the jet stream takes on a very convoluted pattern. When we see it taking big swings north and big dips southward, we know we're going to see some unusual weather conditions."
