That's not a valid conclusion. At best, from your reasoning, you could that the warming
might not be caused by man's activities.
One can accept that there is a cyclical variation in the earth's temperature over hundreds of thousands of years. But what has set off alarm bells is that the present upward trend has ocurred in decades, not millenia.
As I said earlier in this thread you have to take into account rate of change.
