Ask yourself: if these events had occurred 10 or 20 years ago what would have been your reaction?

It is possible that the 'Global warming' hoax was introduced to condition the populace to a situation that could be attributed to a source that is psychologically tenable (i.e 'we did it') instead of an external source (e.g a galactic cyclical event). If the people discovered that they were truly helpless to change what was happening and that its source was even more powerful and devastating than we can imagine, society would descend into chaos.
