Hurricane Impact and Climate Change

Climate change is intensifying hurricanes by making them wetter, windier, and more intense. The ocean's surface heat fuels these storms, leading to stronger winds. As the planet warms, hurricane wind speeds and the proportion of intense hurricanes are expected to increase. A warmer atmosphere holds more moisture, resulting in heavier rainfall during storms. Climate change is also causing storms to move more slowly, allowing them to dump more water in one place. The hurricane season is shifting, with storms reaching peak intensity further north and occurring earlier in the year. This trend poses a threat to mid-latitude cities unprepared for such storms. Globally, similar patterns are observed, with cyclones and typhoons forming earlier than usual.

How does climate change affect the intensity of hurricanes?

• It makes them less intense.

• It has no effect on their intensity.

• It only affects their speed.

• It makes them wetter, windier, and more intense.

How does a warmer atmosphere affect rainfall during hurricanes?

• It decreases rainfall.

• It only affects the wind speed.
