南美洲亚马逊热带雨林早发生严重山火，巴西地理学家周四（28日）发表研究报告，指雨林火灾产生的黑碳，或加剧安第斯山脉的冰川融化。

里约热内卢州立大学地理研究学院科学家迪马加良斯涅托率领团队，利用2000年至2016年间发生的火灾事件、烟羽流动、降雨和冰川融化数据，制作电脑模型，评估亚马逊流域有机物燃烧对玻利维亚Zongo冰川的影响。

他们发现有机物燃烧产生的黑碳等气雾，会随风扩散到安第斯山脉的热带冰川，并沉降在冰雪中，令积雪反射阳光的比率减少，可能令冰川融化加剧。

他们重点分析2007年至2010年的情况，当时亚马逊流域的火灾季最为严峻。

电脑模型显示，黑碳和燃烧物粉尘分别令冰川每年融化速度增加3%至4%；若两者同时产生作用，冰片融化速度则增至6%。如果粉尘或黑碳浓度够高，单是前者已可令冰川每年融化速度增加11%至13%，后者更增至12%至14%。
