the problem with that is that it misses some jkey points


1) it is true that earths temperature changes over eons and that there were colder/warmer times but the evidence also shows that temperature changes in the past took a long time to happen (degrees/centuries instead of degrees/years)

2) that continents and places move, that the earth wobbles.... so that some places that were warmer/colder were that way because they were different then now and you need to look at world temp and not (for example) was Antartic once warm. (it was, partially because it used to be in a more equatorial position)

3) that we know some things that cause the changes and we know that they are caused by us. so it becomes are we 90% responsible or 100% or 70% , so why not decrease the effect we have

4) we need to live on this planet, yes there where times when it was warmer/ colder and there were times when there were dinosaurs and mammoths, neither of which survived their climate changes.
