Forests play an important role
in stemming global warming by absorbing
carbon dioxide -- the most abundant Greenhouse gas -- from the atmosphere . But
a study says that trees have slowed their response to a warming climate. The trees were
slowing down the process of sprouting leaves. The slowdown suggests a
current and possible future weakening of forests' carbon uptake due to the
declining temperature sensitivity of trees.The researchers found that the trees' response (to earlier
spring) had declined over the past three decades, and strong winter warming may
further reduce it.The authors believe the trees may be trying to protect themselves against cold weather.
