Please join us for our LA Climate Reality monthly chapter call, featuring a conversation with climate scientist Dr. Joshua B. Fisher.

Dr. Fisher’s research focuses on terrestrial ecosystems, water, carbon, and nutrient cycling using a combination of remote sensing, supercomputer models, and field campaigns from the Amazon to the Arctic, with applications in water and ecosystem management, food security, wildfire, and environmental justice. He completed his undergraduate and graduate degrees from UC Berkeley and his postdoctoral work from the University of Oxford. Dr. Fisher was a NASA Scientist at the Jet Propulsion Laboratory (JPL) for over a decade and the founding Science Lead for the ECOSTRESS mission on the International Space Station.

Dr. Fisher is now the Science Lead for Hydrosat and Associate Professor of Environmental Science and Policy at Chapman University. In 2026, Dr. Fisher was named an AGU  Fellow. With over 275 publications, Dr. Fisher has been named one of the world’s “most influential” researchers, in the top 0.1% of scientists with papers in the top 1% by citations for the past 8 years in a row.
