Like many fruit crops, the loss of winter chill is likely to negatively impact blackberries as winters continue to warm. In the Pacific Northwest, the source of 95% of the processed blackberry market, a variety of changes are occurring that have the potential to affect production. These include increasing annual average temperature, increasing incidence of heatwaves, and water shortages. Climate change is also impacting indigenous harvest patterns in Arctic regions. Berry harvest usually occurs after the end of salmon runs. However, now the timing of berry ripening and the peak of salmon run are occurring at the same time, making co-harvesting far more difficult, leading to impacts on cultural food ability.
Yields of major staple crops like wheat and rice are being hurt by increasing temperatures. Wine grape production is moving to cooler climes causing changes in the character of some of our favorites. The flavors and health benefits of teas, the size of potatoes, the sting of a hot pepper, where fish call home in the oceans, and a future decline in protein in vegetables—it’s all changing.
Our food database shows the ingredients affected by a changing climate.
