The graph of the November rainfall shows at first glance normal variations from year to year.

However, there has been a notable decrease in the November rainfalls during the last few years.

The physicist Leo Szilard once announced to his friend Hans Bethe that he was thinking of keeping a diary: 'I don't intend to publish, I am merely going to record the facts for the information of God.' 'Don't you think God knows the facts?' Bethe asked. 'Yes' said Szilard. ‘He knows the facts, but he does not know THIS version of the facts'
