对于那些仍然怀疑全球气候变化的人来说,这七张新图表应该能消除他们的疑虑。 今天上午,政府间气候变化专门委员会(IPCC)发布了一项名为“气候变化 2013:物理科学基础”的六年研究的首份公开摘要。 摘要包含了报告中的图表,并解释了图表背后的数据。 这些图表作为一个整体,展示了过去几十年来的明显趋势:全球许多地区的平均地表温度升高了高达 2.5 摄氏度,全球海平面上升了 20 厘米,北极夏季海冰面积缩减了 400 万平方公里,等等。

在为发布详细信息而举行的新闻发布会上,瑞士伯尔尼大学的托马斯·斯托克(Thomas Stocker),同时也是报告撰写工作组的联合主席,表示气候变化是我们时代最严峻的挑战,并补充说:“它威胁着我们的星球,我们唯一的家园。” 联合国秘书长潘基文通过网络视频在新闻发布会上发表讲话,他说:“热度已经来临。我们现在必须行动。” 联合国于 1988 年召集 IPCC,以评估地球气候状况以及人类活动对其造成改变的程度。 来自 39 个国家的 600 多位科学家作者评估了约 9,000 份同行评审研究和 54,000 条评论,最终形成了这份最新报告。
