" the cause of the acceleration in the day’s melting to an atmospheric event, called an anticyclone, above the continent. Anticyclones are regions of high pressure which enable the air contained within them to sink."
That atmospheric event has been taking place for eons. Long before humans began burning carbon for energy and releasing CO2. Such melting events have taken place before and will take place again, regardless of what "scientists" try to do to prevent or mitigate them.
