Overview

James Hansen is affiliated with Columbia University in the United States. Their research primarily focuses on environmental science and agricultural and biological sciences, with notable specialization in global and planetary change, atmospheric science, and ecology, evolution, behavior and systematics. Their work also extensively covers geophysics and soil science.

The main topics addressed in Hansen's publications include climate variability and models, climate change impacts on agriculture, meteorological phenomena and simulations, agricultural risk and resilience, CO2 sequestration and geologic interactions, and geological and geochemical analysis as well as geological and geophysical studies worldwide.

Hansen has contributed to the following peer-reviewed papers:

  • Potential for large-scale CO2 removal via enhanced rock weathering with croplands, 2020, Nature
  • ENACTS: Advancing Climate Services Across Africa, 2022, Frontiers in Climate
  • Impact pathways from climate services to SDG2 ("zero hunger"): A synthesis of evidence, 2022, Climate Risk Management
  • Flexible forecast presentation overcomes longstanding obstacles to using probabilistic seasonal forecasts, 2022, Frontiers in Climate
  • Modeling farmers' preference and willingness to pay for improved climate services in Rwanda, 2022, Environment and Development Economics

Hansen frequently collaborates with several researchers, including:

  • Tufa Dinku
  • Anthony Whitbread
  • Rémi Cousin
  • Amanda Grossi
  • Edward R. Carr

Their publications appear most often in the following venues:

  • Frontiers in Climate
  • International Journal of Economics and Financial Issues
  • Nature
  • Climate Risk Management
  • Environment and Development Economics

Over the course of their career, Hansen has received multiple recognitions, including being named a Fellow of the American Geophysical Union in 1993, election to the National Academy of Sciences in 1996, membership in the Academia Europaea in 1999, and receiving the BBVA Foundation Frontiers of Knowledge Award in 2016.
