Modelling non-stationary tree growth responses to global warming

Project description

Tree growth tracking to improve climate variability reconstruction

Tree rings represent a fundamental archive for the high-resolution reconstruction of climate alterability over the past 1–2 ka at regional and global levels. Accurate reconstructions require a constant relationship between tree growth and climate. However, during the second half of the 20th century, tree-ring width and density chronologies were not able to track the rapidly increasing temperatures in Northern Hemisphere forests. This phenomenon, called the "divergence" problem, questions the reliability of tree-ring based temperature reconstruction and our understanding of the earth’s climate response to anthropogenic greenhouse gases. The EU-funded MONOSTAR project will develop a model that simulates year-to-year and long-term alterations in both the tree-ring width and density of varying conifer species growing under diverse climate environments. The model will be combined with data from a new hemispheric network of tree-ring width and density chronology as well as in situ monitoring data.
