The ongoing COVID-19 outbreak pandemic is now a global crisis. It has caused 9+ million confirmed cases and 400,000+ deaths at the time of writing and triggered unprecedented preventative measures that have confined a substantial portion of the global population and established ‘social distancing’ as a new global behavioral norm. The COVID-19 crisis has affected all aspects of everyday life and work, and heavily impacted the global economy. This crisis also offers unprecedented insights into how the global climate crisis may be managed, as there are many parallels between the COVID-19 crisis and what we expect from the imminent global climate emergency. Reflecting upon the challenges of today's crisis may help us better prepare for the future. Here we compile a list, by no means comprehensive, of the similarities and differences between the two crises, and the lessons we can learn from them: (i) High momentum trends, (ii) Irreversible changes, (iii) Social and spatial inequality, (iv) Weakening of international solidarity, and (v) Less costly to prevent than to cure.

正在进行的 COVID-19 爆发大流行现在是一场全球危机。在撰写本文时，它已导致超过 9 万例确诊病例和 40 万多人死亡，并引发了前所未有的预防措施，这些措施限制了全球大部分人口，并将“社会疏远”确立为新的全球行为规范。COVID-19 危机影响了日常生活和工作的方方面面，并严重影响了全球经济。这场危机还为如何管理全球气候危机提供了前所未有的见解，因为 COVID-19 危机与我们对迫在眉睫的全球气候紧急情况的预期之间存在许多相似之处。反思当今危机的挑战可能有助于我们更好地为未来做好准备。在这里，我们编制了一份清单，绝不是全面的，
