Solar storm warning as ‘major blackouts’ threaten life on Earth – scientists raise alarm

Using data from the European Space Agency’s (ESA) Cluster and Swarm missions, scientists were able to establish a link between the oddly named bursty bulk flows and sudden changes in the Earth’s magnetic field. According to a paper published in Geophysical Research Letters, researchers studied bursty bulk flows, which are fast bursts of ions with typical velocities larger than 150 km/s. They found a link between solar storms, bursty bulk flows in the inner magnetosphere and disturbances in the ground level magnetic field which drive “geomagnetically induced currents” on and below Earth’s surface.
