Accepted Answer

Critical Scientific Data at Risk Due to US Budget Cuts

European governments are actively working to reduce their reliance on essential scientific data historically provided by the United States, which is now at risk due to significant budget cuts initiated by the Trump administration. These cuts have led to the dismantling of research programs and the decommissioning of public databases managed by agencies like the National Oceanic and Atmospheric Administration (NOAA). This situation has prompted European nations to enhance their own data collection systems and explore independent avenues for accessing vital information concerning climate change and extreme weather events.
Data Underpinning Climate and Weather Monitoring

The budget reductions to NOAA and other scientific agencies directly threaten data crucial for understanding sea-level rise and predicting extreme weather events. For example, the Danish Meteorological Institute has relied on several US datasets for monitoring Arctic sea ice and sea surface temperatures, information vital for climate projections and public safety. The decommissioning of datasets, such as the 20 related to earthquakes and marine science announced by NOAA between April and June, highlights the immediate impact of these cuts on the availability of foundational scientific information.
Ocean Observation and Global Research Systems

A significant area of concern for European officials is the potential impact on the Global Ocean Observing System, a network supported by NOAA's research arm. This system is critical for navigation services, shipping routes, storm forecasting, and risk modelling for the insurance industry. Furthermore, the Argo program, a global system of floats monitoring ocean conditions, which NOAA has described as the "crown jewel" of ocean science, is particularly vulnerable. The United States funds 57% of the Argo program's annual operating expenses, and proposed budget cuts in the White House's 2026 plan include the elimination of NOAA's Office of Oceanic and Atmospheric Research, which oversees such systems.
Infrastructure Planning and Industry Operations

The availability of reliable US-supported data is fundamental for long-term infrastructure investment and the operational viability of key industries. Coastal planners depend on shoreline, sea-level, and hazard data to guide their decisions, while the energy sector utilizes oceanic and seismic datasets to assess the feasibility of offshore drilling and wind farm projects. Without continued access to this information, these sectors face challenges in their planning and investment strategies. The EU's expansion of its European Marine Observation and Data Network aims to provide data on shipping routes, seabed habitats, and marine litter, mirroring and potentially replacing some US-based services.
Efforts to Preserve and Replicate Data

In response to the potential loss of critical data, several European governments are taking proactive measures. Norway has allocated US$2 million to back up and store US data, ensuring continued access. The Danish Meteorological Institute began downloading historical US climate data in February as a precautionary measure. German scientific organizations are reviewing their reliance on US databases. This "guerrilla archiving" effort, as some have termed it, involves scientists worldwide downloading US databases slated for decommissioning, though the long-term sustainability of such efforts is limited without significant governmental funding and infrastructure.
