I have tapped my own trees and doubt this is due to climate change. In fact more warm days would probably increase production. The days when you get the best and most sap is when there is a cold night (sub freezing) followed by a warm day. Warming would push this earlier in the season but it would still happen. The only way production would be halted or impacted significantly would be if we stopped having sub freezing nights the entire winter. Sap after the trees bud for the spring is less desirable as it has a stronger flavor.
