130 years, (the amount of time man has been keeping meteorlogical/climate data- and the timespan on the 3 graphs you show) is virtually a speck in the geological and climactic history of the Earth.
They have taken ice core samples I believe, that go further back, but I don't have that data.
LIke others have said, I do believe man certainly can and does have an effect on our environment. (extinction of species, nuclear waste, deforestation, etc), but I'm not sure about "planetary effects".
Far better it seems, is to focus back on pollution, deforestation, (which can cause climate change) and resource management. Things we do know are happening, have a definite cause and which are detrimental to man and the environment.
:D Also, I know nuclear winter is from a nuclear exchange. I used the term as a comparison with volcanos, as I have heard several scientist do. The similarities are the amount of debris and smoke they both toss up into the upper atmosphere, resulting in a loss of sunlight and cooling temperatures.
Good discussion and many good points on all sides.
