"Global warming is a largely natural phenomenon. The world is wasting stupendous amounts of money on trying to fix something that can’t be fixed." 
"What I think is this: Man is responsible for a PART of global warming. MOST of it is still natural."
Global warming "is the biggest scientific hoax being perpetrated on humanity. There is no global warming due to human anthropogenic activities. The atmosphere hasn’t changed much in 280 million years, and there have always been cycles of warming and cooling. The Cretaceous period was the warmest on earth. You could have grown tomatoes at the North Pole"
"The essence of the issue is this. Climate changes naturally all the time, partly in predictable cycles, and partly in unpredictable shorter rhythms and rapid episodic shifts, some of the causes of which remain unknown."

"Personal attacks are difficult and shouldn't occur in a debate in a civilized
society. I can only consider them from what they imply. They usually indicate a
person or group is losing the debate."
