PCH has always had a backlog of orders because of the popularity of their products. I had to wait three months for my A-110. It was well worth the wait.

People always whine because our society demands instant gratification and, if they don't get their way, they stamp their feet and threaten to cancel their orders. Please feel free to cancel your order because there's a more deserving person waiting in line right behind you.

@Kimo. You're correct in saying that there have been episodes of global warming in the past. In most of those cases the cause of the global warming is known; the exception being the Paleocene-Eocene Thermal Maximum, 55.8 million years ago. It's not understood yet what triggered PETM although there are several theories. PETM occurred rather quickly, geologically speaking, taking about 20,000 years.

However, what we're seeing now is occurring blazingly fast. We're now seeing the warming of the earth in just decades, with the catastrophic results occurring in a century or less.

The cause of the current global warming trend is not cyclical, nor is it natural. Natural change has never occurred with this kind of speed. There is no doubt whatsoever that it's caused by humans.
