evidence: Earth’s global sea levels are rising – and are doing so at an accelerating rate. Waters in the ocean are expanding as they absorb massive amounts of heat trapped by greenhouse gases in Earth’s atmosphere. Glaciers and ice sheets are adding hundreds of gigatons of meltwater into the oceans each year. The land surface along the coasts is also creeping up and down, affecting relative sea level rise. People are feeling the impacts, as seemingly small increments of sea level rise become big problems along coastlines worldwide. [...] In 2014, NASA created a Sea Level Change Science Team to bring together experts from across the agency and at other institutions that study different aspects of this multidisciplinary problem. Scientists studying glaciers, ice sheets, ocean physics, land movement and more are brought together to tackle what sea level rise looks like now – and what it will look like in the future.
