The 2025 hurricane season has become a focal point for discussions on climate change, illustrating how global warming is reshaping weather patterns.This year, the season was marked by an unusual phenomenon: while the total number of storms was average, the intensity of those storms was alarming, with three reaching Category 5 status, the second highest on record for a single season.

npr.orgThe relationship between climate change and hurricane intensity is supported by scientific models that predict an increase in rainfall rates and storm surge due to rising sea levels.

npr.orgClimate models suggest that as the planet continues to warm, the conditions for wind shear may become more prevalent, potentially leading to fewer storms but with greater intensity.

npr.orgThe implications of these changes are profound.As climate change continues to alter the conditions under which hurricanes form, the potential for catastrophic flooding and damage increases.The National Oceanic and Atmospheric Administration (NOAA) has noted that rising sea levels, driven by climate change, will exacerbate the impacts of storm surges, leading to higher coastal inundation levels during hurricanes.
