Which greenhouse gas is directly responsible for an increase in the frequency and strength of storms across the globe?Group of answer choicesWater vaporNitrogenMethaneCarbon dioxide

The greenhouse gas directly responsible for an increase in the frequency and strength of storms across the globe is Carbon dioxide.

Here's why:

1. Carbon dioxide (CO2) is one of the primary greenhouse gases and is released into the atmosphere through natural processes like respiration and volcano eruptions, and through human activities such as deforestation, land use changes, and burning fossil fuels.

2. When CO2 is released into the atmosphere, it absorbs and emits infrared radiation, which warms the Earth's surface. This is known as the greenhouse effect.

3. The increase in the Earth's temperature due to the greenhouse effect causes more water to evaporate from the oceans, leading to more moisture in the atmosphere.

4. This increase in atmospheric moisture can fuel more intense storms. Warmer air can hold more water vapor, which can lead to more frequent and intense precipitation, including storms.

5. Therefore, by contributing to global warming and the increase in atmospheric moisture, carbon dioxide is directly responsible for an increase in the frequency and strength of storms across the globe.
