What are the long term effects of climate change? (Choose 3)
Correct Answer(s)
C. Higher temperatures
D. Longer droughts
F. Higher sea levels
Explanation
The long-term effects of climate change include higher temperatures, longer droughts, and higher sea levels. As the Earth's temperature rises due to increased greenhouse gas emissions, it leads to a range of consequences. Higher temperatures can disrupt ecosystems, cause heatwaves, and impact human health. Longer droughts result in water scarcity, affecting agriculture, ecosystems, and human populations. Rising sea levels are caused by the melting of glaciers and ice sheets, which leads to coastal flooding, erosion, and displacement of communities. Increased ozone layer, reduced CO2 emissions, and increased glaciers are not directly linked to climate change and are not long-term effects of it.

Additionally, building on sensitive or undeveloped land can disrupt the natural flow of water, leading to increased runoff and a higher demand for artificial rainwater management systems.
32.
A building owner's project includes a major HVAC renovation, significant envelope modifications, and core plumbing renovation. An interior fit-out is not part of the project. What LEED rating system would be most appropriate for this project?
Correct Answer
B. LEED BD+C: Core and Shell
Explanation
Based on the information provided, the most appropriate LEED rating system for this project would be LEED BD+C: Core and Shell. This is because the project involves major HVAC renovation, significant envelope modifications, and core plumbing renovation, which are all related to the building's core structure and systems. Since an interior fit-out is not part of the project, the LEED ID+C: Commercial Interiors rating system would not be suitable. The LEED BD+C: New Construction rating system is typically used for projects that involve new construction from the ground up, so it may not be the best fit for this project. LEED O+M: Existing Buildings is focused on the ongoing operation and maintenance of existing buildings, so it would not be appropriate for a project involving major renovations and modifications.
