Cold War concerns about the containment of communism were a priority for President Dwight Eisenhower, who had been a prominent military general before becoming president. His concerns for increasing and strengthening America's national security gave impetus to the plan to create an interstate highway system.
Eisenhower, the former general, had seen how Germany's Autobahn system of highways had been an asset to their strength. He came to see highways as an important part of our country's national defense. When Eisenhower gave a speech to Congress in 1955, to promote the building of a federal highway system, he listed safety on the roads and economic advantages as strong reasons for the huge project. But he also listed a national security reason, saying: "In case of an atomic attack on our key cities, the road net must permit quick evacuation of target areas, mobilization of defense forces and maintenance of every essential economic function. But the present system in critical areas would be the breeder of a deadly congestion within hours of an attack" (Special Message to the Congress Regarding a National Highway Program, <span>February 22, 1955).

Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic conditions in glacial and interglacial periods.
