My other point to him at the time was that the Industrial Revolution was actually quite limited and that it wasn't until the forties last century that industry spread, but he ignored this as he ignored the email about getting rid of the MWP and LIA and when I found the Vostok data, and began to appreciate the great cycles within our Ice Age, he dismissed these too and came back to the claim that our temps had been «flat normal» and our fault that we were changing this by our increased production of carbon dioxide as the Hockey Stick showed.
