Air pollution is a global problem and initiatives to counter the phenomenon are obviously necessary. In some circumstances, however, such interventions can generate paradoxical consequences<\/strong>, thus complicating climate mitigation. This is the case with actions taken over decades to improve air quality<\/strong> which, a study<\/a> published in the journal Ecology now claims, may have contributed to a reduction in soil carbon accumulation<\/strong> in an American forest area.<\/p>\n The research, conducted by scientists from the University of Michigan and the University of Wisconsin<\/strong>, analysed the rates of nitrogen<\/a> deposition in the soil, which had decreased due to international agreements to curb pollution.<\/p>\n
