Those who think they are smarter than all the scientists and experts who have been warning about global warming for decades, those who think what's the harm in a few degrees warming where they live, those who think it doesn't affect them. They cannot see past the end of their noses, and have no concept of how global warming affects everything on earth. They don't care the irreversible damage we are doing to earth. They denegrate people who are actually trying to do something to stop it, while having no clue as to what it is.
