The term tipping point has been used to describe elements of the Earth system that might, in the face of changing climate, behave non-linearly, irreversibly, or both. This study will address the likelihood of various physical components of the Earth system to undergo major and rapid changes (i.e., abrupt climate change) and, as time allows, examine some of the most important potential associated impacts and risks. This study will explore how to monitor climate change for warnings of abrupt changes and emerging impacts and examine gaps in our current scientific understanding and monitoring capabilities.

“临界点”一词被用来描述地球系统中的元素，这些元素在气候变化面前可能表现为非线性，不可逆或两者兼而有之。这项研究将探讨地球系统的各种物理组成部分发生重大和迅速变化的可能性（即，气候突变），并在时间允许的情况下，审查一些最重要的潜在相关影响和风险。这项研究将探讨如何监测气候变化，以预警突然变化和新出现的影响，并审查我们目前的科学认识和监测能力的差距。
