摘要
Predicting long-term trends in 森林 growth requires accurate characterisation of how the relationship between 森林 productivity and climatic stress varies across climatic regimes. Using a 網絡 of over two million tree-ring observations spanning North America and a space-for-time substitution methodology, we forecast 氣候 impacts on future 森林 growth. We explored differing scenarios of increased water-use efficiency (WUE) due to CO2-fertilisation, which we simulated as increased effective precipitation. In our forecasts: (1) 氣候 change negatively impacted 森林 growth rates in the interior west and positively impacted 森林 growth along the western, southeastern and northeastern coasts; (2) shifting 氣候 sensitivities offset positive effects of warming on high-latitude 森林s, leaving no evidence for continued
