But climate change itself might compromise how permanently forests are able to store carbon and keep it out of the air, according to a new paper by researchers at University of Utah and UC Santa Barbara. The study considered how different regions and tree species will respond to climate change. The authors found a wide range of estimates for the amount of carbon that forests in different regions might gain or lose as the climate warms. Importantly, the researchers found that regions most at risk of losing forest carbon through fire, climate stress or insect damage are precisely those regions where many forest carbon offset projects have been set up.
“Forest health and carbon-storage potential is evolving rapidly due to climate change,” said co-author Anna Trugman(link is external), an assistant professor at UC Santa Barbara. “The balance of increasing productivity from higher CO2 levels and accelerating losses from disturbances will determine the fate of forests as a carbon sink.” Read more at: University of California – Santa Barbara
