Rising seas may damage an important base tracking space debris in the coming decades after the Air Force ignored the potential ramifications of climate change.

The Associated Press reported Tuesday that the almost $1 billion Space Fence project in the Marshall Islands is placed on an atoll that could be damaged by intruding saltwater in coming decades. The report said the military and its contractor, Lockheed Martin, didn’t give serious consideration to the effects of climate change when picking a location for the base, despite warnings from local officials.
