Global warming has been happening since our planet was formed. Prior to the last ice age, global warming had a significant impact on our planet. To say we as humans have not contributed is nonsense. Can we slow it down, unlikely. But should we put people out of work due to global warming concerns and environmental concerns, I think not. Enjoy the warm earth and do your part to decrease your own carbon footprint. If it (global warming) concerns you then dont buy products from companies that contribute to it.
