With the success of the first edition of the Science Webinar and the interests shown by the YESS community, the team comprising members from the Online Events and Science Working Groups launches the second edition of the Science Webinar series. The goal of the webinar series is to keep the community well informed with the latest research and broaden their knowledge in areas of the Earth sciences. The online activities have been helpful in the professional development of early-career researchers and keep them motivated during these uncertain times.
Water resources change in Central-Western Argentina under the Paris Agreement warming targets
Dr Juan Rivera (Argentina)
This study analyses the projected changes in several components of the hydrological cycle over Central-Western Argentina (CWA) based on the simulations from the IPSL-CM6A-LR model for the warming levels proposed in the Paris Agreement. Our results show that the timing of reaching the 1.5 °C warming level would be between 2032 and 2036 in the CWA lowlands east of the Andes, while the timing of reaching this warming level in the Andes mountains of CWA is expected to be 10-15 years earlier as result of the enhanced warming with elevation. Even following the more aggressive mitigation pathways available in the scientific literature (SSP1-1.9 and SSP1-2.6), the IPSL-CM6A-LR model ensemble shows a robust drying signal in the wintertime precipitation over the Andes mountains, implying a reduction of the scarce water resources draining to the adjacent semi-arid foothills.
