Amount of carbon stored in forests reduced as climate warms

Accelerated tree growth caused by a warming climate does not necessarily translate into enhanced carbon storage, an international study suggests.
The team, led by the University of Cambridge, found that as temperatures increase, trees grow faster, but they also tend to die younger. When these fast-growing trees die, the carbon they store is returned to the carbon cycle.
The results, reported in the journal Nature Communications, have implications for global carbon cycle dynamics. As the Earth’s climate continues to warm, tree growth will continue to accelerate, but the length of time that trees store carbon, the so-called carbon residence time, will diminish.
During photosynthesis, trees and other plants absorb carbon dioxide from the atmosphere and use it to build new cells. Long-lived trees, such as pines from high elevations and other conifers found across the high-northern latitude boreal forests, can store carbon for many centuries.
