However, that debate is resolved, geoscientists increasingly agree that the crust, the oceans and the atmosphere were never truly separate systems, and their fragile equilibrium is now responding, in concert, to the stress humans have placed upon it.

"However, that debate is resolved"为让步状语从句，意为"无论这场争论最终如何解决"，为全句让步背景，与后文形成对比；
"geoscientists increasingly agree that…"为主句，that引导宾语从句，宾语从句内部由and连接两个并列分句："the crust, the oceans and the atmosphere were never truly separate systems"与"their fragile equilibrium is now responding…to the stress humans have placed upon it"；
第二个并列分句中，humans have placed upon it为省略关系代词that/which的定语从句，修饰the stress，还原后即(that) humans have placed upon it。

无论这场争论最终如何解决，地球科学家们如今越来越普遍地认同：地壳、海洋与大气从来都不是真正彼此独立的系统，它们脆弱的平衡正在共同应对人类施加于其上的压力。
