Due to complex interactions with socioeconomic conditions, climate- induced trends in crop yields and production do not directly transmit to crop prices, availability of food, or nutrition status. This complexity, in addition to the limited availability of long-term data, has so far impeded the detection and attribution of a long-term impact of climate change on associated food security indicators. However, in a few cases, observed crop prices  are shown to be sensitive to fluctuations in local weather through its impact on production . In addition, there is growing evidence that climate extremes  have led to malnutrition  in the historical period  but without an attribution of changes to long-term climate change.
