The Warner-Lieberman bill on climate change – a piece of legislation which was recently abandoned in the US Senate but is seen as a precursor of future policy – would have postponed the temperature increase in 2050 by about two years. Recently, the Copenhagen Consensus project gathered eight of the world’s top economists – including five Nobel laureates – to examine research on the best ways to tackle 10 global challenges: air pollution, conflict, disease, global warming, hunger and malnutrition, lack of education, gender inequity, lack of water and sanitation, terrorism, and trade barriers.
关于气候变化的华纳－李伯曼（Warner-Lieberman）法案－一个最近被美国参议院废弃但是被认为是未来政策的先驱的立法－本来到2050年已经延缓气温上升大约两年时间。最近，哥本哈根共识计划聚集了八位全球顶级的经济学家－包括五位诺贝尔奖获得者－来审查有关迎接10个全球挑战最好的方法的研究，这10个挑战包括：空气污染，冲突，疾病，全球变暖，饥饿和营养不良，教育缺乏，性别不平等，水和卫生设施缺乏，恐怖主义以及贸易壁垒。
