As the past two decades have shown trying to get global agreement on tackling climate change seems to be futile. By comparison, more focused and limited interest of elites, however, are easier to push through, such as wars based on geopolitical threats (real and imaginary), or economic crises (where banks and other elites most responsible for the crises are bailed out by ordinary citizens).
Furthermore, as the West has generally shown in the past decade or more (even when their economies were doing good) paying now for something that seems to be a problem in the future is hard to accept. It is easier, therefore, to stall and keep blaming China, India and other emerging nations despite the historical inequality of those emissions. But ignoring that makes it easier to hope these emerging nations will pick up the burden of addressing emissions rises.
