Climate Change

I think that the phrase "Global Warming" is not a good phrase to use and I would much rather talk about "Climate Change". Whether or not man is responsible for the various manifestations that are perceived to come from the change in climate may be open to scientific debate but, to a deep ecologist, there can be no removal of the effects of man's activities on the environment from the impact this may have. Can the earth continue to self-regulate itself purely to the advantage of mankind? I believe that even small changes in a local microclimate can change the wider macroclimate. There are no closed systems in the natural cycles and rhythms of the development and running of the earth. Perhaps the earth is doing 'her own thing' irrespective of man's activities, but does that absolve us from any responsibility for our actions...? Have we evolved to such an extend that we can exist separately and independently from the natural world?
