Most of the people on Earth at this time will be unaware. They may be aware of drought, of a reddish glow during the heat of the day, perhaps even a reddish dust coloring their water and giving a bitter taste to their drinking water. Even those who might take notice can scarce do anything about it. This is an unknown experience. There is no precedence in memory.
Denial is high.
The authorities will not encourage the propagation of information, wishing calm and for the status quo to continue. Even where there is awareness, there will be little action. Many will look about them, and debate their lifestyle should they take action. Should they be forced to become beggars, they may stay in their own, familiar, surroundings. Then there are those who will cling to their material goods.
