Even if we remained on our current trajectory, keeping temperatures from rising more than 2º Celsius above pre-industrial levels – the threshold beyond which the most disruptive consequences of climate change would be triggered – would be next to impossible to achieve. As the Intergovernmental Panel on Climate Change’s most recent report reinforced, we cannot afford a slowdown in progress.
即使保持现有趋势，将气温限制在前工业化水平以上2℃之内——超过这一阈值就有可能引发灾难性后果——也将是难以完成的目标。正如政府间气候变化专门委员会（Intergovernmental Panel on Climate Change）最近的报告所强调的，我们决不能在这方面减慢速度。
