印度尼西亚政府计划通过投放干冰来应对严重的森林火灾烟霾问题。协调安全部长杜东·阿卜杜拉赫曼表示，这次干冰驱散试验是在总统直接指示下进行的，周四将有一架塞斯纳飞机在南苏门答腊城市巴邻旁上空投放1.5吨干冰1。
自1月以来，印度尼西亚全国已烧毁近90万公顷土地，成为十多年来最严重的火灾季1。由森林火灾产生的有毒烟霾已蔓延至新加坡、马来西亚、菲律宾等邻国，造成严重的区域性污染问题1。中加里曼丹省的空气污染指数在周三超过1,200，达到危险水平300的四倍1。
尽管政府采取措施，但专家对干冰消烟的效果持谨慎态度。新南威尔士大学灌木火研究小组副教授瑞克·麦克雷表示，干冰只能提供"局部短期救济"，并非永久解决方案1。烟霾危机对邻近地区造成广泛影响：新加坡上周被列为全球污染最严重的城市之一，当局推行烟霾相关医疗补贴并向居民分发N95口罩1；东帝汶宣布从周四起全国停课三天1；新加坡还提出集体诉讼，指控政府"严重过失"，数万人因烟霾寻求呼吸道疾病治疗1。
Indonesia's government launched a dry ice cloud-seeding operation Thursday in South Sumatra as toxic wildfire smoke continued to blanket the region and affect neighboring countries.1 A Cessna aircraft dropped 1.5 tons of dry ice over the city of Palembang as part of an experimental smoke-dispersal effort.1 Coordinating Security Minister Dudi Tjahjono stated that the trial was "undertaken on the direct instruction of the president."1
The fire crisis has reached unprecedented severity, with nearly 900,000 hectares burned across Indonesia since January—marking the worst fire season in over a decade.1 The air quality deterioration has extended well beyond Indonesia's borders, with Singapore last week ranking among the world's most polluted cities.1 In Central Kalimantan province, the air pollution index exceeded 1,200 on Wednesday, more than four times the "dangerous" threshold of 300.1 Singapore initiated smoke-related medical subsidies and distributed N95 masks to residents starting Monday, while East Timor announced a three-day national school closure beginning Thursday.1 The pollution's severity prompted thousands to seek respiratory treatment, and a class-action lawsuit was filed against Singapore's government last week alleging "gross negligence."1
However, experts cautioned that the dry ice approach offers only limited relief. Rick McRae, associate professor of bushfire research at the University of New South Wales, characterized dry ice dispersal as providing "localized short-term relief" rather than a permanent solution to the crisis.1
