No controversy here — the sky (actually coronal mass) is falling!!! But never fear NOAA has the answers on all things solar flair-ish.
“When these coronal mass ejections hit Earth’s own magnetic field, they energize the Earth’s magnetic field and cause it to fluctuate” said SWPC physicist Doug Biesecker, Ph.D. During a moderate or strong storm, such fluctuations can temporarily impair navigation, power, satellite and other systems.
