Time is running out
Alarm bells are ringing on all sides. Reports published by the UN Intergovernmental Panel on Climate Change (IPCC) confirm human responsibility for global climate change. More than 15,000 scientists say it will “soon be too late to deviate from our path doomed to failure, because time is running out”. The UN deplores the fact that greenhouse gas emissions are stagnating at 52 billions of tons per year, whereas they should be limited to 36 or even 24 for global temperature rise to stay below 2 °C, which would allow a peaceful future. The 2017 UN Climate Change Conference, COP 23, displayed a sense of helplessness. The commitments made two years previously at COP 21 will lead to an increase of 3 to 3.5 ° C. But let's remain optimistic, there is still time: “We have 3 years to act,” warn Jean Jouzel and Pierre Larrouturou.
