Along the walls of Oceanographer Canyon, fish dart in and out of colorful anemone gardens and sea creatures send up plumes of sand and mud as they burrow. Bill Ryan, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory, watched the scenes through the windows of a mini research submarine in 1978 as he became one of the few people to explore the seafloor canyons that President Obama has now designated a national monument.

Scientists have developed a new model to help coastal planners assess the risks of sea level rise. Put to use on a global scale, it estimates that the oceans will rise at least 28 centimeters on average by the end of this century – and as much as 131 cm if greenhouse gas emissions continue to grow unchecked.

Why does sea level change at different rates? How has it changed in the past? Who will be at risk from more extreme weather and sea level rise in the future? Our scientists often hear questions like these. To help share the answers more widely, we created a new app that lets users explore a series of maps of the planet, from the deepest trenches in the oceans to the ice at the poles. You can see how ice, the oceans, precipitation and temperatures have changed over time and listen as scientists explain what you’re seeing and why.
