Rising Sea Levels Trajectory: Satellite data has been essential in forecasting sea level rise, helping scientists plan and prepare for potential catastrophes. NASA’s detailed record of satellite images has allowed scientists to understand this global trend better, providing scientists with important data they can use to plan ahead for potential tragedies.
Since 1993, NASA’s TOPEX/Poseidon mission began measuring sea surface height; subsequent missions led by France’s CNES space agency, European Space Agency and US National Oceanic and Atmospheric Administration also collected essential information.
NASA’s website reports the newest mission as Sentinel-6/Jason-CS (Continuity of Service). This two satellite constellation will continue taking measurements until at least 2030 and collect data to better comprehend how sea levels are rising across coastal communities.
NASA conducted an analysis of satellite data which revealed that the average global sea level rose 0.11 inches (0.27 centimeters) between 2021 and 2022. To put this into perspective, this is equivalent to adding water from one million Olympic swimming pools into the ocean each day for one year.
Since 2001 when TOPEX/Poseidon began, sea levels have risen an average of 3.6 inches (9 centimeters). Long-term satellite predictions predict levels could continue rising at this rate through 2050, increasing by 0.26 inches (0.66 centimeters) annually by then
Nadya Vinogradova Shiffer, a NASA programme scientist for ocean science, stated that “Timely updates are essential to accurately gauge our climate trajectory.” NASA’s satellite record of Rising Sea Levels Trajectory will remain an invaluable tool to comprehend the effects of climate change on Earth.
Satellite missions provide a global snapshot of sea level changes, enabling scientists to recognize patterns and trends. This knowledge is essential for policymakers and government agencies as they craft strategies for mitigating climate change effects like implementing coastal protection measures, relocating communities in high-risk areas, and reducing greenhouse gas emissions.
In addition to providing insights into climate change impacts, satellite records of sea level rise have important ramifications for industries dependent on coastal infrastructure like shipping, fishing and tourism.
As sea levels continue to rise, these businesses will face increased risks from storm surges and flooding that could cause significant economic losses. By using data collected by these satellites, stakeholders in these industries can better comprehend these potential dangers and develop strategies to adapt to shifting coastal conditions.
