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.”
Ralph Keeling, on behalf of the Board.

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. Deborah Clark, a Research Professor at UMSL, spent 30 years living at La Selva Biological Station, in Costa Rica. For 14 years, she was the first (Co-) Director of the Station with her husband David Clark, while conducting forest research. She also taught undergraduate and graduate field courses in tropical ecology, in the Brazilian and Peruvian Amazon, Mexico, and Costa Rica. In 1994, with La Selva now a premier site for tropical research and education, she became a full-time independent researcher funded by grants from diverse agencies, principally the National Science Foundation. With David and colleagues, she focused on questions that could only be resolved through highly quality-controlled long-term measurements. These multi-decade studies produced the first evidence that higher nighttime temperatures are reducing tropical rainforest productivity, in spite of limited benefits from increasing atmospheric carbon dioxide.
Deborah received her undergraduate degree in Biology from the University of North Carolina, Chapel Hill, and her Ph.D. in Zoology at the University of Wisconsin, Madison, based on field research in the Galapagos Islands. She is an AAAS Fellow and past President of the Association for Tropical Biology and Conservation.
