I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.

You know, entropy is associated thermodynamically, in systems involving heat, with disorder. And in an analogous way, information is associated with disorder, which seems paradoxical. But when you think about it, a bit of information is a surprise. If you already knew what the message contained, there would be no new information in it.
