The layer that is responsible for protecting Earth is in danger. A massive chunk of the layer has been reportedly weakening and has caused a dent in the Earth’s shield. The phenomenon is called South Atlantic Anomaly (SAA) and is splitting into two and getting wider as time progresses. The SAA has been named after its location over South America and Southern Atlantic Ocean.
The magnetic field around the Earth acts as a protective shield which repels and traps charged particles from the Sun. As of now, NASA says the deepening rift in the SAA has no visible impact on daily life on the surface but recent forecasts have shown the region is expanding westwards and is increasingly growing weaker.
NASA says, “The South Atlantic Anomaly is also of interest to NASA’s Earth scientists who monitor the changes in magnetic field strength there, both for how such changes affect Earth’s atmosphere and as an indicator of what’s happening to Earth’s magnetic fields, deep inside the globe.
