In arguing that the United States or other high -
emitting nations need not reduce their ghg emissions to their fair share of safe global emissions based on cost, how have you considered, if at all, that all
nations have
agreed in international climate negotiations to take steps to limit warming to 2 degree C because warming greater than this amount will not only create harsh impacts for tens of millions of people but runs the risk of creating rapid non-linear warming that will outstrip the ability of people and
nations to adapt?
