Earth's magnetic field is weakening reveal ESA scientists, interfering with satellites

While global air travel is yet to commence in full strength as countries open up after Coronavirus lockdown, scientists at  European Space Agency (ESA), on Saturday, revealed that earth's magnetic field is weakening between Africa and South America, as per international reports. This phenomenon gared by ESA's Swarm constellation of satellites has allegedly caused issues for satellites and space crafts. ESA states that phenomenon known as South Atlantic Anomaly has grown considerably in recent years, reason is unclear.

Why is Earth's magnetic field weakening?

Scientists state that data gared by ESA has shown that area of anomaly dropped in strength by more than 8 percent between 1970 and 2020. ESA has mused that a possibility for weakening field is a sign that Earth's magnetic field is about to reverse. reversal will cause  North Pole and South Pole to switch places. 

reversal of poles called 'geomagnetic reversal' reportedly took place was 780,000 years ago. Scientists have claimed that such a reversal us long overdue as such reversals take place every 250,000 years. Repercussions of such reversal will be significant for Earth.

What will happen if Earth's magnetic pole reverses?

reversal of magnetic poles will affect Earth's magnetic field which protects planet from solar winds and harmful cosmic riation. magnetic field also affects Telecommunication and satellite systems and a reversal will disrupt computers and mobile phones. ESA has warned spacecraft flying in area experiencing South Atlantic Anomaly of "technical malfunctions", while satellites orbiting Earth are alrey having issues.

Scientists have stated that despite weakening field, "Earth's magnetic field is probably not reversing", as per a 2018 study. study has explained that process is not an instantaneous one and could take thousands of years to take place. Meanwhile, ESA continues to monitor weakening magnetic field using Swarm satellites, still trying to configure origin of South Atlantic Anomaly.

Earth is 'standing still'

Recently, scientists revealed that with entire world at a standstill due to COVID-19, planet too seems to 'standing still'. According to recent studies by seismologists drastic reduction in human activity has caused Earth to move substantially less. With reduction in movement of  Earth's crust, seismologists believe that y will be capable of detecting even smallest tremors - despite fact that many of scientific instruments in use today are near city centers.
