"I recall we children being walked to the school stairwell to practice in case of nuclear attack. Later, during the 1962 Cuban missile crisis, I recall grownup men looking scared."

"During the Cold War, no one could see how it could go away. But it did," she says.

"Global warming is the new overarching challenge. But it's heavy stuff to think about.
