Our planet's thermosphere—which is the second-highest layer of the atmosphere—has now recorded the highest temperature compared to the past two decades. The reason behind this spike is the series of geomagnetic storms that struck Earth this year. That's not all, the thermosphere's temperature is likely to edge higher in the coming years as the Sun's activity increases. Let's see what impact this will have.
