The correct answer is: d) All of the above.
Climate change is projected to increase the frequency and intensity of droughts and heatwaves, cyclones and floods, and coastal erosion and sea-level rise.
Droughts and heatwaves are caused by a lack of rainfall. Climate change is projected to lead to a decrease in rainfall in some areas, which could lead to more frequent and severe droughts. Heatwaves are also caused by high temperatures, which are projected to increase due to climate change. This could lead to more frequent and severe heatwaves.
Cyclones and floods are caused by high winds and heavy rainfall. Climate change is projected to lead to an increase in the frequency and intensity of cyclones and floods. This is because warmer oceans provide more energy for cyclones, and warmer air can hold more moisture, which can lead to heavier rainfall.
Coastal erosion and sea-level rise are caused by the rising sea level. Climate change is projected to lead to a rise in sea level, which could lead to more coastal erosion and flooding.
These are just some of the ways in which climate change is projected to affect our planet. It is important to be aware of these changes and to take steps to adapt to them.
