Looks at the specific implications of climate change to orchard crops, ways to adapt and mitigate risk through new agricultural technologies to mitigate heat stress, and increasing and selecting for varietal diversity.

Part 1: What Changes Have Already Occurred?

Length: 00:05:28 | Robert Crassweller, Ph.D.

As you've just seen, the evidence behind climate science indicates that a number of changes have already occurred, which have had an impact on orchards.

Since 1980, weather patterns such as rainfall quantity and duration, temperature and extreme weather events have become increasingly erratic.

Tree fruit production is weather dependent from the early spring bloom development and potential for frost, to short intense drought periods and hail events during the growing season through erratic fall weather impinging harvest. As climate change progresses what might be the possible effects on fruit production practices, what might be ways to ameliorate those effects?
