Answer:
Solar flares come from sunspots, and when they are heavy, it is common for television, radio and cell phone use to become problematic to a certain degree (more an annoyance than anything). This same activity also causes the Aurora Borealis, or "Northern Lights". It is suspected that sunspot activity over repeated long periods (lasting several hundred years each) may be connected to climate fluctuations here on earth, but this is still being investigated.
