I would suggest reading Federalist # 10 , but the short answer is that homogeneity breeds majority factionalism and is at greater risk of running roughshod over people whose circumstances diverge from theirs . I really don ' t put much faith in the opinions of slaveholders on modern society . They couldn ' t envision the invention of the semiauto , much less any of the modern communication tools that are intrinsic to our society today . The solution , however , is to find a way to work together , lol what the fuck ? Work together to do what ? Agree that Climate Scientists might be right ? You think there ' s a compromise with the Republicans on this ? What would that be , exactly ? and this is true both internally within our country and externally as a foreign policy objective between countries . It ' s called the Paris Climate Agreement . It ' s been done . The guy dumbfuckistan just elected President over my strong objections is going to abandon it on his first day in office . So much for working together . A first step would be identifying those areas that are easiest to develop an agreed upon approach , like conservation this can also be sold as energy independence and the promotion of green energy production in areas negatively impacted by losses in polluting industries . I don ' t think you understand the magnitude of the situation . 2 degrees of warming correlates to a sea level rise of 8 meters this floods the island of Manhattan . This is the level of temperature increase we expect to see if we stop all CO 2 production today . Like at this instant . Conservation , etc , isn ' t going to do it . In your lifetime we will have to abandon large areas of cities on the East and Gulf Coast . Find ways to decouple the issue from the more immediate needs of people like their job and connect it to things they care about and the opposition will disappear . Wow , I wish someone had thought of that . sigh This is clearly not a U . S . only phenomena . The graph you linked does not measure climate change denial . It measures perceived threat . I live a few hundred feet above sea level and own land a lot of it much further inland . I perceive no real threat from climate change . There are people who believe it doesn ' t existwe can ' t do anything about it . You can ' t ' negotiate ' that away .
