It was The International Geophysical Year (IGY), and the discoveries made during that year established a new foundation for science that affects our lives nearly every day. In The Year Science Changed Everything, author Mark O’Connell charts the struggles and successes of 1957’s International Geophysical Year alongside interviews with today’s leading environmental scientists to show that the time is right for another global
