Climate has always shifted but concerns about faster changes brought on by the modern world have led the authors of a new
paper to worry that current high-volume sources of apples could lose their apex status to other areas.
The paper in the pay-to-publish journal
Environmental Research Letters analyzed over 40 years of climate conditions they correlate to the growth cycle, bud break to fruit, of apple trees. They sound the alarm that the largest apple-producing counties in the US (Yakima in Washington, Kent in Michigan and Wayne in New York) have already been impacted.
