作为NASA地球科学事业（ESE）分计划之一的ESE研究战略，在未来10年中，将主要关注以下 5个科学问题：①全球地球系统是怎样变化的？②地球系统的主要驱动力是什么？③地球系统如何响应自然和人为引起的变化？④地球系统的变化对人类文明造成的后果是什么？⑤如何更好地预测地球系统未来的变化？这 5个问题都是大范围的跨学科问题，涉及到地球系统科学的各个方面。在这 5个大的科学问题之下，又具体细化为23个二级问题，并对这些问题进行了极其详尽的讨论。

As one of division plan of NASA Earth Science Enterprise (ESE), ESE Research Strategy is focusing on the five fundamental science questions on the Earth system as follows: (1)How is the global Earth system changing? (2)What are the primary forcings of the Earth system? (3)How does the Earth system respond to natural and human-induced changes? (4)What are the consequences of change in the Earth system for human civilization? (5)How well can we predict future changes to the Earth system? The five questions are concerned with each section of the Earth system. Under the five questions, there are 23 sub-tier questions that are discussed in more detail. [WT5HZ]
