Cyclones are not the result of climate change. But climate change/global warming exacerbates the impact of cyclones. Warmer water is "fuel" for cyclones. AGW has warmed the oceans. Storm surge kills. Storm surge is on top of AGW-induced sea level rise. Precipitation extremes result in flooding. AGW results in increased precipitation. These are all basic, physical responses to warming. AGW is not responsible for these events, but it makes these events more impactful.
