Climate Science Funding Dries Up, US Influence Shrinks

The Intergovernmental Panel on Climate Change (IPCC) is facing a budget shortfall after the United States government ended its funding and withdrew from the body, prompting member states to discuss how to replace both financial support and scientific capacity.

Officials involved in the process have been weighing alternative funding arrangements and ways to sustain the flow of research that underpins IPCC assessments. The shift comes as the United States had previously been a leading contributor to the IPCC’s scientific work, including staffing and expertise used to compile major reports.

On the IPCC’s sixth assessment, the United States contributed 74 researchers , underscoring the scale of its earlier role. Even after the government withdrawal, more than 70 US scientists are still participating through non-profit organizations, according to the information provided, but the absence of official government backing has left a gap that member states are now trying to address.

At the same time, other countries are increasing their scientific investments. European countries and China are among those expanding their contributions, reflecting a broader rebalancing in where publicly supported climate research capacity is growing. The material also notes that China is projected to surpass the United States in publicly funded research within two years , alongside a marked rise in its academic input to climate science.

Beyond staffing and funding for assessments, the withdrawal is also described as affecting key data resources used by researchers globally. A specific example cited is the defunding of the Emergency Events Database (EM-DAT) by the US Agency for International Development (USAID) , which is presented as a warning sign for the continuity of widely used public datasets that support climate-related analysis.

For governments and institutions that rely on IPCC findings, the immediate issue is how to maintain the organization’s operational capacity and the breadth of expertise feeding into its reports. The longer-running question raised by the developments is how shifts in public funding and data stewardship could change the global infrastructure that supports climate research, particularly when widely shared datasets face uncertainty.
