Earth Day is important to us here at The Earth Institute because it’s the one day of the year when everyone celebrates something that matters a lot to us: our beautiful planet.
Earth Institute scientists have been investigating the planet’s mysteries for more than 70 years. They have plumbed the depths of the oceans, scaled the tallest mountains, and traversed every continent in order to broaden and deepen our understanding of the world. Along the way, they’ve made incredible discoveries that shook the world of science.
Researchers at our Lamont-Doherty Earth Observatory were the first to propose that ice ages are driven by natural cycles of freezing and thawing in the Arctic Ocean. Lamont’s Marie Tharp was the first to map the ocean floor on a global scale. Mark Cane and Stephen Zebiak, researchers at our International Research Institute for Climate and Society, helped to create the first model to explain and predict the powerful El Niño climate cycle, which affects affect crops, disease outbreaks and natural hazards all over the world. And the term “global warming” came from our own Wallace Broecker, who was among the first scientists to warn of the dangers of rising global temperatures.
