My father, who has become too deaf to listen to reason, bores us with news of the weather. We have lost the sense of seasons; our climate has been degenerating since the first nuclear explosion in Nevada a generation ago. He remembers that radioactive clouds traveled from Nevada to upstate New York and that all the exposed negatives in the Kodak laboratories in Rochester were damaged. He says he saw a news item about it in an early edition of a Montreal paper, but that in the later editions it had been left out. Did we read it then? Do we think about it now?
