Germany is constructing the CMIP7-ark ark to safeguard U.S. climate data from potential political interference by the Trump administration. The project involves installing 5 petabytes of storage at the DKRZ in Hamburg, expanding the existing 254 petabytes. This initiative supports the U.S. contribution to the 2029 U.N. climate assessment and follows a $35 million budget approved in late 2025. The operation aims to prevent data loss due to U.S. government actions, though the specific mechanisms for data transfer remain undefined.
