With climate change, it’s important to better understand the frequency and strength of precipitation events and how they may affect inland flooding. San Francisco undertook a unique collaboration between a municipality, climate scientists at Lawrence Berkeley National Laboratory, and climate consultants at Pathways Climate Institute to create a research team that focused on a better understanding of future precipitation events through climate modeling. Using supercomputing resources at LBNL’s National Energy Research Scientific Computing Center, the research team found that the effect of
