Chemistry 2003 JAMB Past Questions - Question 13: A consequence of global warming is

Correct Answer

A

Explanation

Global warming can have several consequences, and the listed options are connected to various aspects of this phenomenon:

1. **Air Pollution:** Global warming can contribute to increased levels of air pollution. Rising temperatures can lead to the intensification of certain air pollutants, such as ground-level ozone. Additionally, the increased frequency and intensity of wildfires, often associated with global warming, release large amounts of particulate matter and pollutants into the air.

2. **Water Pollution:** Changes in temperature and precipitation patterns can affect water quality. Higher temperatures can lead to increased evaporation, reducing water levels and concentrating pollutants in water bodies. Additionally, extreme weather events associated with global warming, such as heavy rainfall and storms, can lead to runoff carrying pollutants into rivers and oceans.

3. **Increased Humidity:** Global warming can contribute to changes in regional climate patterns, including increased humidity in some areas. While this might not directly cause pollution, it can influence the distribution and concentration of certain air pollutants and impact ecosystems.

4. **Flooding:** Global warming is associated with the melting of glaciers and polar ice caps, leading to rising sea levels. This can result in coastal flooding and the inundation of low-lying areas. Floods can have various consequences, including the displacement of communities, destruction of infrastructure, and the release of pollutants from flooded areas into water bodies.

It's important to note that the specific consequences of global warming can vary by region and depend on various factors, including geographical location, local climate, and human activities. The interactions between different environmental systems are complex, and the consequences of global warming often manifest in interconnected ways.
