I'm always confused as to why a scientific theory, with well documented and well supported evidence, has become an issue of political belief in the US.
We've obviously had a major impact on the environment, but rising sea levels are not the main threat. The outcome as described in the video is a rather simplistic view; most political discussions of global warming usually are. More pressing is the decline of local animal populations due to pollution - if bee's die out, then we have a more urgent catastrophe and famine in poorer countries.
