How Will Climate Change Affect Water Supplies? - The Water Cycle

The video discusses how climate change affects drought conditions. As the world warms, storm tracks that bring winter moisture to the western US are projected to move north, expanding dry regions. Additionally, a warmer atmosphere can hold more moisture, leading to increased evaporation and evapotranspiration, which dries out the soil and exacerbates drought conditions.

How does climate change affect storm tracks in the western US?

• Storm tracks disappear completely.

• Storm tracks move northwards, expanding dry regions.

• Storm tracks remain unchanged.

• Storm tracks move southwards, increasing rainfall.

What is one consequence of storm tracks moving northwards?

• Increased snowfall in the southwestern US.

• Expansion of dry regions in the southwestern US.

• More frequent hurricanes in the southwestern US.

• Decreased temperatures in the southwestern US.

What is the expected change in winter rainfall due to climate change?

• Decrease in winter rainfall from the Pacific.

• No change in winter rainfall patterns.

• Winter rainfall will become more unpredictable.

• Increase in winter rainfall from the Pacific.

How does a warming climate affect soil moisture?

• It has no effect on soil moisture.

• It decreases soil moisture by increasing evaporation.

• It increases soil moisture by reducing evaporation.

• It makes soil moisture more stable.

What process contributes to drier soil as the climate warms?

• Photosynthesis and respiration.

• Condensation and precipitation.

• Erosion and sedimentation.

• Evaporation and evapotranspiration.
