Why Germany is building an ark for US climate data
In a modern five-story building in the center of Hamburg, Germany, technicians are preparing to install several new “racks” — gray metal casings that hold computing hardware — alongside the scores that already line the narrow, dimly lit corridors of the German Climate Computing Center, or DKRZ, one of the world’s largest repositories for climate simulation data. The new equipment will add about 5 petabytes of storage capacity to the 254 petabytes of data already stored here. One petabyte of data is equivalent to the storage space needed for roughly 200 million high-resolution images.
Under normal circumstances, the DKRZ’s mission is to provide computing power and storage to the German climate science community. But these new racks will serve a different and highly sensitive purpose: They will store backup versions of climate simulations from the other side of the Atlantic. …
