NASA and international panel offer new window on rising seas


In addition to providing snapshots of sea level rise in the decades to come, the tool allows users to focus on the effects of the different processes that cause sea level rise. These processes include the melting of ice caps and glaciers and the extent to which ocean waters change their circulation patterns or expand as they warm, which can affect the height of the ocean.

“As communities across the country prepare for the impacts of sea level rise, access to good, clear data is essential to help save lives and livelihoods,” said the NASA administrator Bill Nelson. “NASA’s New Sea Level Projection Tool will provide America’s people and policymakers with the information they need to make critical economic and public policy decisions to protect our communities from the potentially devastating effects of sea level rise. from sea level. “

The tool can display possible future sea levels under several greenhouse gas and socio-economic emissions scenarios, including a low-emission future, a “business as usual” trajectory with emissions on their way. current and an “accelerated emissions” scenario. A low-emission future, for example, would occur if humanity reduced its greenhouse gas emissions, thereby mitigating the effects of climate change from sea level. The other end of the emission spectrum gives projections with the fastest sea level rise, information that could be useful for coastal planning that takes into account less likely but potentially more destructive possibilities.

“The goal is to provide the projection data in the IPCC report in a usable form while providing easy visualization of future scenarios,” said Ben Hamlington, a researcher at NASA’s Jet Propulsion Laboratory in Southern California, who runs the Sea Level agency. Change the scientific team.

The sea level projection tool should help people at all levels of government in countries around the world to forecast future scenarios and develop coastal resources accordingly. “Making sea level science accessible is our primary goal,” said Carmen Boening, a NASA oceanographer who also runs the agency’s Sea Level Portal, which hosts the projection tool.
