Concept notes: Global warming can lead to changes in climate patterns, which can affect the distribution of disease vectors such as mosquitoes. As temperatures rise, these vectors can expand their range into areas that were previously too cold for them, leading to the spread of diseases to new regions.

Common Mistakes: A common misunderstanding is that global warming will uniformly decrease the frequency and intensity of extreme weather events, or that it will lead to a decrease in global temperatures.

Explanations: Global warming is expected to cause a rise in temperatures, which can facilitate the spread of disease vectors such as mosquitoes and ticks. These vectors are often limited by cold temperatures, and as temperatures increase, they can move into new areas, potentially spreading diseases that were previously confined to the tropics.

Option Analysis:

Option A: This is incorrect because global warming is expected to increase the frequency and intensity of extreme weather events, including hurricanes.
Option B: This is correct because global warming can lead to the spread of diseases previously limited to the tropics as disease vectors expand their range.
Option C: This is incorrect because global warming is expected to cause an increase in global temperatures, not a decrease.
Option D: This is incorrect because global warming is expected to cause sea levels to rise due to the melting of ice caps and thermal expansion of seawater.
