Low Water Level on Lake Kariba

03.24.2023
Altimetry satellites including Sentinel-6A/Michael Frelich have measured the water level at Lake Kariba—the world’s largest reservoir and a major source of electricity in Zimbabwe and Zambia. The data show that since 2022, the lake level has dropped sharply.
sea levels (in blue) from data recorded by a series of five satellites starting in 1993. The solid red line shows the trajectory of rise from 1993 to 2022, illustrating that the rate of rise has more than doubled. By 2040, sea levels could be 3.66 inches (9.3 cm) higher than today

NASA Uses 30-Year Satellite Record to Track and Project Rising Seas

03.17.2023
Observations from space show that the rate of sea level rise is increasing. Knowing where and how much rise is happening can help coastal planners prepare for future hazards. Since satellites began observing sea surface height in 1993 , the average global sea level has increased by 3.6 inches (9.1 cm), according to NASA’s Sea Level Change Team.
