While the end result of planetary warming may be the same, the mechanisms are different.

Its not a great direct comparison... but it does indicate the likelihood that human factors are not fully responsible, or even, that they represent a small portion of what is causing the change. This is important to ascertain so proper measures can be taken. If climate change isn't a solely human induced phenomenon, then Kyoto and its "pollution credits" should be tossed out the window, and focus should be made on technological efficiency and mitigating the damage caused by change.
