Climatic changes will bring many and complex effects for forests and different bioclimatic regions. Rising atmospheric CO2 concentration, higher temperatures, changes in precipitation, flooding, drought duration and frequency will have significant effects on trees growth. These climatic changes will also have associated consequences for biotic – frequency and consequences of pests and diseases outbreaks and abiotic disturbances - changes in fire occurrence, changes in wind storm frequency and intensity with strong implications for forests ecosystems. The study assesses potential impacts, the adaptive capacity of the forests, and the resulting vulnerability and risks of these direct and indirect impacts on the capacity of forests to provide economic, social and ecological services.
