In mid-September, Storm Boris brought massive rainfall to Central and Eastern Europe, causing floods that claimed 24 lives and inflicted $2-3 billion in damages. Early warnings and infrastructure improvements helped mitigate the impact. A study by the World Weather Attribution group found that human-caused climate change doubled the likelihood of such intense rainfall and increased its severity by 7%. Climate scientists warn that if global temperatures rise by 2°C, such events will become 50% more likely and more intense. The storm, a “Vb” system, stalled over the region, exacerbating the flooding.
