What are some of the arguments against the existence of global warming?
Some of the arguments against the existence of Global Warming include the lack of long-range reporting data. With data on global temperature only going back – at best – a hundred years or so there is not enough information to say for certain that the planet is on an unnatural warming trend. For example if one scientist points out that temperatures and ocean levels are rising, another will ask why the reason for the change has to be human impact, and not simply part of a natural planet/ climate cycle.
