After the narrow passage of the Waxman-Markey climate-change bill in the United States House of Representatives, Krugman said that there was no justification for a vote against it. He called virtually all of the members who voted against it, “climate deniers” who were committing “treason against the planet.”
而诺贝尔经济学奖得主保罗·克鲁格曼在这方面则走得更远。在华克斯曼-马基气候变化法案在美国众议院以微弱优势通过之后，克鲁格曼说那些反对票都是无理取闹，还把那些投了反对票的议员都认定为触犯了“背叛地球罪”的“气候否定者”。
