# 气候变化与生物多样性丧失

我们迫切需要一个可互操作的全球生物多样性计量单位，以便所有利益相关方共同努力，守护地球生态。 

在21世纪，地球正经历物种丧失，其速度之快已被称为“第六次大灭绝事件”。 [(2)](https://sciwheel.com/work/citation?ids=4934855\&pre=\&suf=\&sa=0). 2022年，超过196个国家同意根据《昆明—蒙特利尔全球生物多样性框架》（GBF）采取紧急行动，到2030年保护至少30%的地球表面——重点关注高风险生物多样性生态区，以防止物种发生灾难性崩溃 [(3, 4)](https://sciwheel.com/work/citation?ids=7013008,16133214\&pre=\&pre=\&suf=\&suf=\&sa=0,0). 然而，根据项目管理科学和大型项目的历史，我们知道，只有就如何衡量成功达成一致，这一努力才可能成功 [(5, 6)](https://sciwheel.com/work/citation?ids=16439095,16545226\&pre=\&pre=\&suf=\&suf=\&sa=0,0). 

生物多样性协定既滞后于碳协定，也受益于碳协定所汲取的经验。气候通过全球平均温度变化进行跟踪，而碳排放则通过二氧化碳公吨进行量化。迄今为止，生物多样性行动和跟踪之所以受阻，正是因为尚无这样一个商定的单位 [(7)](https://sciwheel.com/work/citation?ids=16545253\&pre=\&suf=\&sa=0). 

解决这一问题有一个简单方案，但这种简单性依赖于一个视角转换，采取多学科方法，并消除意识形态分歧，以共同目标为先。
