The impact of climate change on extreme weather events is a highly discussed topic. Extreme weather events such as heavy rain, droughts, hurricanes, etc. occur frequently worldwide, causing significant impacts on people's lives and the economy. Scientific research indicates that climate change is one of the main causes for the increase and intensification of these extreme weather events.

Firstly, climate change has led to a global rise in temperatures. With the increase in greenhouse gas emissions, the Earth's climate system has been disrupted, resulting in a global temperature increase. This temperature rise increases the amount of water vapor in the atmosphere, thereby increasing precipitation. As a result, the frequency and intensity of heavy rainfall events have increased, leading to the occurrence of floods.

Second, climate change also exacerbates drought events. Global warming increases the rate of surface water evaporation and soil moisture evaporation, leading to soil dryness. In addition, climate change alters the pattern of precipitation distribution, causing reduced rainfall in certain areas, further intensifying drought occurrence. Drought has serious impacts on agriculture, water resources, and ecosystems.

In addition, climate change also increases the intensity and frequency of tropical cyclones such as hurricanes. Warm sea surface temperatures provide energy for the formation and development of tropical cyclones. As global temperatures rise, sea surface temperatures also increase, making tropical cyclones stronger and more frequent. Hurricane strikes bring immense destruction to coastal areas, causing casualties and economic losses.

In summary, the impact of climate change on extreme weather events is evident. The global rise in temperatures has led to an increase in the frequency and intensity of extreme weather events such as heavy rainfall, droughts, and hurricanes. To mitigate the effects of climate change, global society should take action to reduce greenhouse gas emissions and promote sustainable development.
