Fig. 2: Temperature and leaf area index anomaly related to Arctic warming.
From: Arctic warming-induced cold damage to East Asian terrestrial ecosystems

a–d Regression coefficients of seasonal mean temperature (°C °C−1) (a, b) and leaf area index anomaly (m2 m−2 °C−1) (c, d) during boreal winter (December–February) (a, c) and spring (March–May) (b, d) onto December–February ART index. Hatching indicates significant regions at the 95% confidence level based on the Student’s t-test. e–g Land cover type fractions (%) of evergreen broadleaf (e), evergreen needleleaf (f) and deciduous broadleaf (g).
