In a breakthrough that could reshape climate modeling, an international research team led by Chinese scientists has uncovered how trees' natural 'breathing' mechanism adapts to rising temperatures – potentially lowering worst-case global warming projections.
The study, published in Science, reveals that tree trunk respiration demonstrates widespread thermal adaptation across ecosystems. By analyzing data from 223 species worldwide, researchers developed the first predictive model showing how this biological process becomes more efficient in warmer conditions.
'This discovery is like finding a hidden thermostat in Earth's forests,' said lead researcher Dr. Li Wei from the Chinese Academy of Sciences. 'As temperatures rise, tree trunks appear to 'breathe' more efficiently than previously assumed, creating a natural buffer against climate change.'
The findings suggest current climate models may overestimate future carbon release from forests by up to 12%. This thermal adaptation mechanism could significantly impact carbon budget calculations used in global climate agreements.
For investors and policymakers, the research highlights the importance of forest conservation in climate strategies. Academics note the database created through this study provides unprecedented insights into terrestrial carbon cycles across Asian and global ecosystems.
