DESCRIPTION: To reduce uncertainties in climate reconstructions the team will: 1) assess climate change impacts on forests to predict future responses using tree ring growth models; 2) explore stable isotopes as a key for the divergence problem; 3) develop more reliable paleoclimate reconstructions by combining tree-ring parameters and non tree-ring archives.
OUTCOMES: 233 samples taken from 31 living and 84 subfossil trees in Alaska have been examined. There is a significant trend towards wider rings after 1900 and even more so after 1950. Tree-ring width corresponds with natural radiative forcing until 1900. Two peer-reviewed journals published.
