Dr. James Butler
Late Board Member
In Memoriam: Dr. James Butler
It is with great sadness that we announce the passing of Board Member Dr. Jim Butler on November 26, 2023. There have been many tributes to Jim, but on behalf of the Keeling Curve Foundation, we want particularly to note how committed Jim was to our mission – the recognition and honoring of those who collect and maintain high-quality, accurate, precise, and timely records of the Earth, its atmosphere, oceans and terrestrial biosphere, that modulate climate change. His specialty was the measurement of greenhouse gases, atmospheric aerosols, and other atmospheric trace species that allow us to quantify and model these changes. During his 35-year career at the National Oceanic and Atmospheric Administration (NOAA), 17 of which were as Director of its Global Monitoring Laboratory in Boulder, Colorado, he made an immense contribution, as a scientist, an innovator, and as a leader. He is remembered by his NOAA colleagues and colleagues around the globe as forward-looking, ever upbeat, and positive. His successor as Director at NOAA, Dr. Vanda Grubišić, wrote that “In addition to his scientific accomplishments, Jim’s legacy will be the positive influence he had on the personal and professional lives of a wide array of students, post-docs, colleagues, and friends across the globe with his generous heart, insightful intellect, and endless enthusiasm for science and for life.”

Julio Betancourt is a Scientist Emeritus with the U.S. Geological Survey. Dr. Betancourt’s research focuses on how climate variability and change drive regional drought, flood, and fire frequencies in the U.S., and how to define baselines of environmental change from seasonal to millennial timescales. He played a leading role in reconstructing vegetation dynamics during the last 50,000 years in deserts of the Americas. His early work on how tropical Pacific variability influences the annual occurrence of floods and wildfires in the American West challenged critical assumptions in flood frequency estimation and helped jumpstart the emerging field of fire climatology. Concerned about ‘season creep’ with climate change, he helped establish the USA National Phenology Network (NPN), a large-scale network of repeated and integrated plant and animal phenological observations, and the tools to analyze them at local to national scales. To date, 25,000 NPN volunteers at 19,000 sites have collected over 35 million records for over 1700 plant and animal species.
Julio is a Fellow of the American Geophysical Union (2009). He has received honors from the USGS, U.S. Department of Interior, White House, Ecological Society of America, American Water Resources Association, Geological Society of America, and the American Quaternary Association.

Dr. James Cloern
Late Science Advisory Council Member
In Memoriam: Dr. James Cloern
It is with great sadness that we announce the passing of our Science Advisory Council colleague Dr. Jim Cloern on November 3, 2025. Jim was a superb limnologist and oceanographer who used phytoplankton, and the biogeochemical and ecological processes they drive, as indicators of water quality and ecosystem condition in the world’s estuaries. Using San Francisco Bay as his laboratory, Jim devoted his career to understanding the complexities of estuaries at the interface of rivers, ocean,atmosphere, and dense human settlement. Beginning in 1976, when he joined the USGS National Research Program in Menlo Park, Jim led monthly cruises along a 145-km, deep-water transect to continuously sample the chemical, biological, and physical parameters that quantify estuarine ecological processes from ocean to inland delta. He relied heavily on this now half-century dataset to track the estuary’s response to primary agents of change. Jim’s detection and attribution of significant water quality trends, and his effective communication to policy makers and the public, catalyzed important policy actions. This included tracking over time the effects of the 1972 Federal Clean Water Act and informing dissolved oxygen standards for San Francisco Bay. Jim was a humble recipient of multiple honors and awards, but his most lasting impact was the example he set by always putting humanity — family, integrity, friendships, grace, generosity — above professional success.
