The United States faces multiple political challenges to achieving the rapid cuts in carbon emissions called for by the Intergovernmental Panel on Climate Change. Among these are the long-standing issue of partisan polarization and the newly emerging problem of climate doom and defeatism. These challenges are not only barriers to agenda-setting and enactment, but can also threaten the durability of policies over time. This study uses a survey experiment from a nationally representative sample (n = 1760) to examine the impact of partisan cues and fatalistic rhetoric on support for the climate provisions of the Inflation Reduction Act. We find that Republicans and Independents exposed to Democratic Party cues expressed less support for the IRA. We also find that Independents respondents exposed to a fatalistic message had reduced support for the IRA. These findings underscore the importance of framing in the post-enactment period and suggest that the IRA may be vulnerable to retrenchment or reversal.

美国在实现政府间气候变化专门委员会呼吁的快速削减碳排放方面面临多重政治挑战。其中包括长期存在的党派两极分化问题和新出现的气候厄运和失败主义问题。这些挑战不仅是议程制定和实施的障碍，而且还可能威胁到政策的持久性。本研究使用全国代表性样本 (n = 1760) 的调查实验来检验党派线索和宿命论言论对《通胀削减法案》气候条款支持的影响。我们发现，受到民主党暗示的共和党人和独立人士对爱尔兰共和军的支持较少。我们还发现，受到宿命论信息影响的独立受访者减少了对爱尔兰共和军的支持。这些发现强调了制定后时期框架的重要性，并表明爱尔兰共和军可能容易受到紧缩或逆转的影响。
