目前现有气候模型均未将微塑料纳入辐射强迫计算，该研究指出这一遗漏可能导致气候预测系统性偏低。独立学者对研究结论总体持审慎认可态度，UK 生态与水文中心的 Sam Harrison 博士指出，大气 MNPs 分布及其气候影响仍存在较大不确定性，需要更多证据支持；布里斯托大学气溶胶科学研究员 Jim Walker 亦强调，若该结论得到进一步验证，微塑料或应被纳入黑碳等短寿命气候强迫因子框架，意味着通过减少塑料排放可在较短时间内改善其增温贡献，但这不应转移对主要温室气体减排的关注。

Airborne microplastics could be making climate change worse

Tiny plastic particles drifting in Earth’s atmosphere could have a significant warming effect, a new study finds

Colored microplastics could be making global warming worse

There's more bad news about microplastics. We already know they pose a risk to health and can pollute ecosystems, but now researchers have discovered that tiny plastic particles drifting in Earth's atmosphere could be a significant contributor to global warming.
