Economic Implications of Climate Change for U.S. Agriculture: Assessing Recent Evidence
梳理了气候变化对美国农业经济影响的近期证据，发现全国层面影响尚不严重，但区域和环境冲击可能很大，建议政策聚焦降低不确定性和增强农业灵活性。
Recent studies estimate potential economic impacts of climate change on U.S. agriculture. While results are not directly comparable, several "big picture" lessons can be drawn. These broader findings are developed and put into a policy context. While the estimated impacts on U.S. agriculture, and the U.S. economy, do not yet justify costly adaptation or mitigation strategies, some regional and environmental impacts could be quite severe. Current policy efforts should focus on reducing climate change uncertainties and increasing farm sector flexibility. From a national perspective, future agreements to limit greenhouse gas emissions could be partially met through adjustments of farm practices.
