Climate change is impacting U.S. forests unevenly, with the Western region experiencing a slowdown in productivity, while the Eastern region sees slight growth, according to a study led by UF Biology researchers. The analysis of U.S. Forest Service data from 1999 to 2020 reveals a regional imbalance influenced by climate change drivers. Forests, vital carbon sinks, face challenges as negative effects like droughts counterbalance positive impacts such as carbon-dioxide fertilization. The study urges urgent global emissions reduction to sustain forest health and prevent accelerated climate change, emphasizing the need for collaborative efforts between governments and industries.
