This fourth edition of SBDS is focused on extreme events affecting the Bay-Delta—heatwaves, droughts, atmospheric rivers, and wildfires. The articles explore physical and ecological processes within the Bay-Delta that are responding to changes in large-scale forcing phenomena, primarily those associated with climate change. This SBDS edition offers a regional perspective on the intensifying effects of climate change on the Bay–Delta rather than event-specific attribution studies and analyses.
