WWA researchers are investigating opportunities for sustained assessment in the US Southwest region – an area that includes Arizona, California, Colorado, Nevada, New Mexico, and Utah. The project is drawing on the broad existing capacity for climate assessment in the region, with the goal of connecting climate service providers and users to increase access to information and understanding of climate impacts in decision-making contexts. The project is developing recommendations for sustained assessment efforts in the region. It is being conducted in collaboration with partner RISAs CLIMAS (Climate Assessment for the Southwest) and CNAP (California-Nevada Climate Applications Program). Activities have also been integrated into the RISA Sustained Assessment Specialist network, resulting in the publication Learning from Successes (Grecni et al. 2019).
