In this paper, we examine the response over the period AD 1895-1994 of three tree species growing across northern Europe to increases in atmospheric CO"2 concentrations using parameters derived from stable carbon isotope ratios of trunk cellulose. Using the isotope data we calculate values of intrinsic water-use efficiency (IWUE) and intercellular CO"2 concentrations in the leaf (c"i). Our results show that trees have responded to higher levels of atmospheric CO"2 by increasing IWUE whilst generally maintaining constant c"i values. However, the IWUE of most of the trees in this study has not continued to rise in line with increasing atmospheric CO"2. This behaviour has implications for estimations of future terrestrial carbon storage.
