Abstract: The project “Land-Use and Climate, IDentification of robust impacts (LUCID)” was initiated to address the robustness of possible biogeophysical impacts of land-use induced land cover changes (LULCC). LUCCID used seven coupled atmosphere-land models with a common experimental design to explore those impacts of LULCC that are robust. The biogeophysical impacts of LULCC were also compared to the impact of elevated greenhouse gases and resulting changes in sea-surface temperatures and sea-ice extent. Focussing our analysis on Eurasia and North America, we show that LULCC has, on a number of variables, an impact of similar magnitude, but of opposite sign to increased greenhouse gases and warmer oceans (for more details see attachment). adaptation and mitigation as a part of the solution for vulnerable communities, where Blue Carbon science and policy discussions are up to and what is happening in our region of the world on the ground.

Bio: Nathalie de Noblet-Ducoudré is a bioclimatologist that has spent most of her time trying to understand what roles the terrestrial biosphere plays in the climate system. She first turned her attention towards past climates (mainly the last glacial-interglacial cycle) and contributed to demonstrate that vegetation dynamics are an active player in the climate system that needs to be accounted for in order to simulate climatic transitions. More recently, she turned her attention towards human-induced land cover changes and their influence on climate at the global scale. With Dr. Andy Pitman and with the support of IGBP/iLEAPS and GEWEX/GLASS, Dr de Noblet-Ducoudré has launched the LUCID international intercomparison project. Essentially a modeller, she tries to see whether the knowledge of regional to global land-atmosphere interactions and their potential predictability can help anticipate the consequences of land-use strategies.
