I haven't read the article but all the talk of global reactions has made me ponder the factors that are having a global impact. 3 come to mind:
a. The Credit Crunch in 2008 and the lingering, unequal impact
b. The rise in world population. I was surprised to find when looking at global warming that the world population was about 1.6 bn people in 1900 and over 7 bn now. That is a big rise in, relatively speaking, a short period in human experience.
c. The present day ease of communication, initially through radio and TV but now via mobile phones and the internet.
Are there other global factors that may be influencing people? Personally, I am not sure if the 3 events mentioned are massive shifts. Perhaps there are small shifts in underlying positions which have come to the surface.
