That would be true only if the data that all scientists rely on came from only one source. However, there are many, many data sets from multiple different disciplines that all point to similar conclusions. Ice core samples, tree ring samples, air/gas measures, ocean chemical composition measures, land surface temperature trends, ocean surface temperature trends, extinction patterns at varying temperatures over hundreds of thousands of years, fossil records, decades of visual observations of ice melt, destruction of the worlds largest carbon sink (trees), and on and on and on. The list is so large and covers such a large period of time, the evidence has become overwhelming that this period in man's history is unequivocally a period of warming unprecedented in that it is being caused by man himself.
