Adresat Climate Change as a Risk Multiplier

Climate change amplifies both floods and hurricanes. Warmer air holds more water vapor, increasing the potential for extreme rainfall. Sea-level rise elevates baseline water levels, making storm surges more destructive. Some studies suggest that the proportion of Category 4 and 5 hurricanes is increasing. While no single storm can be attributed solely to climate change, the overall trend is clear. Mitigation strategies must therefore include reducing greenhouse gas emissions, alongside adaptation measures. Communities that pursue both parallel tracks will be more resilient to whatever natural disasters the future holds.
