TL;DR:
1. This is one measurement among many. The honest scientist considers the whole of the data, rather than cherry picking the 1 among N measurements that support his hypothesis.
2. Existence of conflicting evidence is a good reason for more, not less, research.
3. There's nothing to suggest that one set of measurements reflects a trend. The global system is complex, and the existence of surprising phenomena should be a reason to try to understand better, not an excuse to bury our heads.
4. The relationship between stability and total mass is probably not strictly positive and is certainly not linear. So even in the best case scenario, the risk of destabilization should still be studies.
