Final answer:
The implications of more severe hurricanes due to a warming atmosphere include an increased risk of disasters, the necessity for better hurricane preparedness, and heightened climate change awareness, leading to the conclusion that the answer is D. All of the above.
Step-by-step explanation:
When scientists warn that the warming atmosphere is causing bigger and more frequent hurricanes, such as Hurricane Katrina, this raises several implications for people. Firstly, there is an increased risk of hurricane-related disasters, which implies greater potential for loss of life, property damage, and economic disruption.
Secondly, to manage this risk, there is a clear need for better hurricane preparedness, which involves improving warning systems, building infrastructure to withstand stronger storms, and developing evacuation plans. Thirdly, this trend signifies the importance of climate change awareness and understanding its impacts on our environment and society. This awareness can drive actions towards mitigating climate change and adapting to its effects.
Hence, the correct response to the student's question is D. All of the above, indicating that a warming atmosphere leading to more severe hurricanes has multifaceted consequences for individuals and communities.
