"去气候政策化":特朗普第二任期美国气候政治新变化OACHSSCD

Donald Trump,following his return to the White House in 2024,announced the U.S.withdrawal from the Paris Agreement once again on his first day in office,signaling a phase of"deterministic retrenchment"in American climate policy.Under the combined effects of an increasing personalized leadership style,the restructuring of domestic interest configurations,and intensifying great-power competition,U.S.climate politics has exhibited a distinct shift toward"de-prioritization of climate policy".Correspondingly,the politi-cal ecology has been systematically reshaped and further reinforced through the repeated deployment of discursive narratives and policy instruments.As a result,the U.S.climate governance system has become increasingly fragmented,exerting tangible impacts on the global climate consensus and the effective implementation of the Paris Agreement.In essence,this transformation reflects a systematic reconfiguration of policy behavioral logic through the reshaping of political ecology by multiple structural variables.Although this shift constrains multilateral climate processes in the short term,climate cooperation in the long run continues to demonstrate a fundamental trend in which consensus outweighs divergence.
