Severity of crop losses from heatwaves and droughts has tripled in Europe

In short: Researchers analyzing five decades of European agricultural data found that the impact of extreme weather on crops is intensifying. By combining weather disaster databases with agricultural records from 1961 to 2018, the study observed that the severity of production losses linked to heatwaves and droughts has roughly tripled over the last 50 years.

The study used a superposed epoch analysis to evaluate how different extreme weather events affect cereal and non-cereal yields. While the frequency of various weather disasters has increased, the researchers found that the intensity of losses specifically from heatwaves and droughts grew from -2.2% in the 1964–1990 period to -7.3% between 1991 and 2015. The findings may be driven by both climate change and increasing system vulnerability.

Why it matters: Extreme weather is not just happening more often in Europe; its impact on food production is becoming significantly more severe.
