WMO Pays Tribute to Renowned Climate Scientist Antônio Divino Moura

The World Meteorological Organization (WMO) has paid tribute to Antônio Divino Moura, one of the world's foremost experts in weather and climate science, following his passing on 16 April 2026 at the age of 80. Moura's decades-long career helped shape modern meteorology, particularly in Latin America, leaving behind a legacy that continues to influence global climate research and policy.

A towering figure in atmospheric science, Moura made groundbreaking contributions to understanding the El Niño–Southern Oscillation (ENSO) and the complex interactions between oceans and the atmosphere. His work significantly advanced scientific knowledge of how climate variability affects both regional and global weather systems, providing critical insights for forecasting and disaster preparedness.

WMO Secretary-General Celeste Saulo described Moura as "one of the great scientific leaders who shaped meteorology in Brazil," highlighting not only his academic achievements but also his role in building international scientific collaboration. She emphasized that Moura belonged to a pioneering generation that transformed meteorology in Brazil and extended its impact across Latin America through strong regional partnerships.

Moura's leadership within the WMO spanned decades. He served as Brazil's Permanent Representative to the organization from 2011 to 2016 and as WMO Third Vice-President between 2007 and 2011. In his home country, he led Brazil's national meteorological service on three separate occasions, playing a central role in modernizing the institution and strengthening its scientific capabilities.

In recognition of his outstanding contributions, Moura was awarded the International Meteorological Organization (IMO) Prize in 2019—the WMO's highest honor. His acceptance speech reflected the curiosity that defined his career, recalling his early research into the climatic anomaly of the Amazon rainforest existing alongside arid regions in Brazil—an observation that sparked his lifelong exploration of climate dynamics.

Beyond theoretical research, Moura was a pioneer in applying climate science to real-world challenges. He championed the integration of climate forecasts with public health strategies, particularly in combating mosquito-borne diseases such as malaria and dengue fever. By linking rainfall and temperature predictions with disease models, his work helped improve early warning systems and preventive measures, demonstrating the vital role of climate science in safeguarding public health.

Moura also played a key role on the global stage as the founding Director-General of the International Research Institute for Climate and Society (IRI) at Columbia University from 1996 to 2002. Under his leadership, the institute became a leading center for climate research and forecasting, including the development of widely used El Niño and La Niña prediction systems.

His efforts extended to bridging the gap between science and policy. At a time when El Niño was poorly understood, Moura worked tirelessly to inform policymakers in Brazil and internationally about its far-reaching impacts, helping to integrate climate knowledge into decision-making processes.

Brazil's National Institute of Meteorology (INMET) described his contributions as an "inestimable legacy," noting that his influence went beyond institutions to shape generations of scientists and public servants.

Known affectionately as "Totonho," Moura was remembered not only for his intellectual brilliance but also for his dedication, humility, and commitment to improving lives through science. His work underscored the importance of climate services as a public good—helping communities anticipate risks, adapt to environmental changes, and build resilience.

As tributes pour in from across the global scientific community, the WMO extended its condolences to Moura's family, colleagues, and all those who worked alongside him, honoring a life devoted to advancing knowledge and strengthening humanity's response to climate challenges.
