Área de investigación: Cambio climático y paleoclimas.
Descripción
Los esfuerzos de investigación de su grupo de investigación giran en torno a tres temas principales:
1. Reconstrucciones climáticas empíricas. Los archivos paleoclimáticos, como los testigos de hielo y turba, así como los testigos de sedimentos marinos y lacustres, permiten reconstruir la variabilidad climática en el pasado. En particular, mi grupo de investigación se centra en los aerosoles de polvo y su efecto climático directo e indirecto.
2. Modelación climática. Utilizamos modelos globales del sistema terrestre, modelos del sistema terrestre de complejidad intermedia y modelos de evaluación integrados para probar hipótesis sobre el cambio climático pasado, presente y futuro.
3. Impactos del cambio climático. Examinamos los efectos del cambio climático a una escala más regional, centrándonos en las tendencias de sequía y los eventos extremos para comprender sus implicaciones para los ecosistemas locales y los recursos hídricos.
Estudiantes de pregrado, postgrado o postdoctorales, pueden ponerse en contacto con el profesor Fabrice Lambert, si están interesados en el desarrollo de investigación.
English version:
My research group’s investigative efforts revolve around these three main topics:
1. Empirical climate reconstructions. Paleoclimatic archives, such as ice and peat cores, as well as lake and marine sediment cores, allow reconstructing climate variability in the past. In particular, my research group focuses on dust aerosols and their direct and indirect climatic effect.
2. Climate Modeling. We use global Earth System Models, Earth System Models of Intermediate Complexity, and Integrated Assessment Models to test hypothese about past, present and future climate change.
3. Climate change impacts. We examine the effects of climate change at more regional scale, focusing on drying trends and extreme events to understand their implications for local ecosystems and water resources.
Interested undergraduate and graduate students and postdocs please contact me.
