Which of the following statements are correct with regard to the effects of global warming?

(A) Due to global warming, it is believed that heat waves may increase in the future.
(B) Tropical cyclones will be more intense.
(C) It is likely that the area affected by droughts will decrease.
(D) The models indicate that some regions will experience significantly more precipitation and runoff.

Choose the correct answer from the options given below:

Correct option is C

The correct answer is (A), (B), and (D).

• Statement (A) is correct because global warming is expected to increase the frequency and intensity of heatwaves due to higher average global temperatures.
• Statement (B) is also correct. As global temperatures rise, the atmosphere becomes more capable of holding moisture, which can lead to more intense tropical cyclones.
• Statement (D) is correct. Climate models predict that some regions will experience more precipitation and runoff due to changes in atmospheric patterns, leading to increased rainfall in certain areas.

Information Booster:

1. Global warming is linked to the intensification of heatwaves, with rising temperatures amplifying extreme heat events.
2. The increased intensity of tropical cyclones is associated with higher sea surface temperatures, which provide more energy for storm formation.
3. Some regions may face more severe drought conditions due to altered rainfall patterns and increased evaporation from higher temperatures.
4. Climate models suggest a shift in precipitation patterns, with some regions seeing increased rainfall, leading to higher runoff, while others experience dry conditions.
5. Climate change's effects on precipitation and runoff may vary depending on geographical location, topography, and local weather systems.

Additional Knowledge: 

• Statement (C)is incorrect. While some areas may experience less severe droughts, the overall trend with global warming is that droughts are likely to become more severe, particularly in regions already prone to water scarcity.
