I don't think this would be a good idea.

Government agencies may certainly have the power to influence this
enough, perhaps even without the newspaper being aware of it.
The same applies to basically all other "news" items, like the current
lottery numbers, the place of the most recent accident with > 10 death
victims, and so on.

Something that cannot be influenced by humans but is yet measurable by
many must be chosen.
Perhaps something based on the mean temperatures at the 10 biggest
cities in the world at the same date/time.
Or the most recent date/time/intensity of coronal mass ejections or
number of sun spots (which both has again the disadvantage that not many
people can measure it, thus it may again be subject to forgery).


Cheers,
Chris.
