US science organizations to pick up on Trump’s abandonment of NCA
Two major US scientific organizations, American Meteorological Society and American Geophysical Union, will work together to produce more than 29 peer-reviewed journals covering all aspects of climate change, including observations, projections, impacts, risks and solutions.
The AP and the Guardian reported on the development late last week after the Trump administration dismissed all contributors to the sixth National Climate Assessment (NCA), the US government’s major study on climate change. The dismissal of nearly 400 contributors left the future of the study in doubt; it had been scheduled for publication in 2028.
The NCA has been overseen by the NASA-supported Global Change Research Program, a US climate body that the Trump administration also dismissed last month. The reports, published since 2000, coordinated input from 14 federal agencies and hundreds of scientists.
Speaking to the Associated Press, Katharine Hayhoe, a Texas Tech University climate professor and chief scientist at The Nature Conservancy, said the collaboration between AMS and AGU “is a testament to how important it is that the latest science be summarized and available.”
Hayhoe, who was a lead author of reports in 2009, 2018 and an author of the one in 2023, added: “People are not aware of how climate change is impacting the decisions that they are making today, whether it’s the size of the storm sewer pipes they’re installing, whether it is the expansion of the flood zone where people are building, whether it is the increases in extreme heat.”
In addition to widespread dismissals across federal agencies, federal websites have been purged of information pertaining to climate change and extreme weather events since Trump took office in January.
The NCA report is required by a 1990 federal law and was due out around 2027. Preliminary budget documents show slashed funding or elimination of offices involved in coordinating thereport, scientists and activists said in an AP report.
“We are filling in a gap in the scientific process,” AGU President Brandon Jones said. “It’s more about ensuring that science continues.”
Meteorological society past president Anjuli Bamzi, a retired federal atmospheric scientist who has worked on previous National Climate Assessments, said one of the most important parts of the federal report is that it projects 25 and 100 years into the future.
With the assessment, “We’re better equipped to deal with the future,” Bamzi said. “We can’t be an ostrich and put our head in the sand and let it go.”
In the announcement on Friday, the two societies said: “This effort aims to sustain the momentum of the sixth National Climate Assessment (NCA), the authors and staff of which were dismissed earlier this week by the Trump administration, almost a year into the process.”
According to the AMS and AGU, the collection will not replace the NCA but instead create a mechanism for important work on climate change’s impact to continue.
“It’s incumbent on us to ensure our communities, our neighbors, our children are all protected and prepared for the mounting risks of climate change,” AGU’s president, Brandon Jones, said.
“This collaboration provides a critical pathway for a wide range of researchers to come together and provide the science needed to support the global enterprise pursuing solutions to climate change,” he added.
Similarly, the AMS president, David Stensrud, said: “Our economy, our health, our society are all climate-dependent. While we cannot replace the NCA, we at AMS see it as vital to support and help expand this collaborative scientific effort for the benefit of the US public and the world at large.”
The last climate assessment report, released in 2023, said that climate change is “harming physical, mental, spiritual, and community health and well-being through the increasing frequency and intensity of extreme events, increasing cases of infectious and vector-borne diseases, and declines in food and water quality and security.”
In 2018, during Trump’s first term, the assessment was just as blunt, saying: “Climate change creates new risks and exacerbates existing vulnerabilities in communities across the United States, presenting growing challenges to human health and safety, quality of life, and the rate of economic growth.”
