The general objective of my research is to advance in the understanding of the hydroclimatic variability of southern South America at different spatio-temporal scales in the context of global warming. An evaluation of the regional impacts of temperature and precipitation climate extremes in southern South America under specific levels of global warming is addressed. Particularly, following the Paris Agreement of December 2015, there is an international effort to limit global warming to "well below 2°C with respect to pre-industrial levels and to continue efforts to limit the increase in the temperature at 1.5°C with respect to the pre-industrial levels ". The main motivation of the current project is that a better understanding of regional impacts under specific levels of global warming will be able to provide accordingly relevant information to policy and decision makers on mitigation strategies and regional adaptation. The difference in the risks linked to climate change between 1.5°C and 2°C of global warming is quantified based on the simulations of extreme temperature and precipitation indices derived from a set of last generation global climate models (MCGs).
