The climate has been changing for about 4.5 billion years. Greenland got its name for a reason. Man’s presence obviously has an effect on the climate.  So does a warming and cooling sun. Thirty years ago Time, Newsweek, et al were screaming the next ice age was almost here. I don’t know how true the tampering allocation is but knowing what I do about climategate emails tampering is quite likely. Do we know the real net effect of man on the environment? I doubt it.
