Of course, there were all kinds of explanations online, saying that the truly cold season had not arrived yet and that occasional high temperatures were perfectly normal.
However, as time passed and late November arrived, more and more bizarre weather phenomena emerged around the world. Densely populated cities also began coming under "attack." Some cities were even directly struck by widespread thunderstorms, damaging and disrupting large amounts of electronic equipment. What was more, none of these violent convective weather events had been forecast by meteorological departments. It was as though humanity's long-matured weather forecasting technology had suddenly failed across the board.
In truth, though, several major powers had obtained some special information through satellite remote sensing and knew that the source of the recent global climate anomalies lay in Antarctica.
Beginning in mid-October, temperatures in certain parts
