David Salas y Mélia is a climate scientist working at CNRM (Centre National de Recherches Météorologiques, Météo-France & CNRS). His research focuses on the role of land and sea-ice in the climate system. From 1996, he developed a model representing the evolution of Antarctic and Arctic sea-ice that results from the freezing of the ocean surface. He obtained a PhD in physics of the ocean and the atmosphere in 2000. From 2003, he coordinated Météo-France’s first participation in the international Coupled Model Intercomparison Project, with the objective of producing future climate simulations for the IPCC (Intergovernmental Panel on Climate Change) 4th assessment report. His main current field of interest is the past and future response of continental ice sheets to climate change and their contribution to sea-level rise. Since 2016, he his the head of CNRM’s research unit in charge of modelling, understanding and investigating the predictability of climate and atmospheric composition.
