Countries of authors ranked by publication output within the time period 1980–2012 (only countries with at least 1,000 papers are considered).

All contributing authors are considered; this implies a substantial overlap, since the cooperating authors of a specific paper often work in different countries. In addition, the bibliometric indicators PPTop 50%, PPTop 10%, and PPTop 1% of the countries are included: Column (1) includes the impact of climate change papers, and column (2) displays the impact of climate change papers relative to the overall impact of the countries’ papers published between 1980 and 2012.本数据集纳入所有贡献作者；这意味着作者群体存在显著重叠，因为某一特定论文的合作作者往往供职于不同国家。此外，数据集还纳入各国的文献计量指标：PPTop 50%、PPTop 10%与PPTop 1%。第(1)列涵盖气候变化相关论文的学术影响力，第(2)列则展示以1980年至2012年间各国发表论文的总影响力为基准时，气候变化相关论文的相对影响力。
