Hurricanes and Climate Change: What We Know

Climate change intersects with hurricanes by increasing storm rainfall, intensity, and surge. A warming atmosphere causes more evaporation, meaning more water is available for precipitation. For every 1°F increase in temperature, the atmosphere can hold around 4 percent more water vapor, which leads to heavier rain and increases the risk of
