For hundreds of millions of years, the earth has being going in and out of ice ages. At one point, maybe 300 million years ago there was an event called "Ice ball earth" in which the entire earth was covered by ice. There have been 100 theories to explain ice ages, but none have been proven to be correct.
Therefore, while I believe global warming should be studied and monitored, I fail to see how we can be certain that this warming is not part of the earth's natural cycle of going in and out of ice ages.
At present, the normal state of the earth is in an ice age. The dates very, but we generally we spend 100,000 years in an ice age and then pop out into a warming period of 10,000 to 20,000 years that we are in now.
I use the analogy of the mayfly that only lives one day above ground to breed. One may mayfly says to another: "The day is getting warmer and warmer. The end is near." After it is eaten by a toad, the toad says, "The earth heats and cools every 24 hrs."
