Exact excerpt

Per unit leaf area change, the median asymmetry index indicates warming roughly 2.0-2.3 times stronger than cooling in spring and autumn, and about an order of magnitude stronger in winter, where a very small greening-side sensitivity inflates the ratio; in summer both responses approach the detection limit and are not directionally robust. Phenological instability therefore acts as a seasonally structured positive biophysical feedback in northern ecosystems.
