The burden of proof that the world will not end tommorrow is not on the one that says the world will not end tomorrow, but on the one that says it will. I can and have made a pretty strong case for it. But the burden of proof remains with you to convince others of it or not.
There is a 60-80 year sea ice cycle and you completely deny it.
First, if you had been actually listening and reading the references you would know that the 60-80 year cycle is not referenced to Singer but several other scientists. Second, I would be happy to conclude that it was not a 60-80 year nature cycle when a substantial part of that cycle had not gone according to the dynamics of that cycle as laid out in the scientific literature. That could be determined either as a statistical anomaly or just via common sense approach. So I am ready to change my opinions thus as the facts change.
