It may now become complicated to determine the link between climate change and carbon cycle. Thanks to a new study of a deciduous forest in Canada which shows that warm springs can cause trees to increase their take-up of carbon. "It takes up more carbon in years with warm springs,' says Andy Black of the University of British Columbia. The study found that the average annual temperature has little impact, but the earlier trees come into leaf, and the warmer the weather, the more carbon they take up ( Geophysical Research Letters , Vol 27, p1271).
