APES Climate Change Evidence and Impacts
39 flashcards covering APES Climate Change Evidence and Impacts for the AP-ENVIRONMENTAL-SCIENCE Unit 9 section.
The topic of Climate Change Evidence and Impacts is a critical component of the AP Environmental Science curriculum, specifically outlined in Unit 9. This unit addresses the scientific basis for climate change, including greenhouse gas emissions, global temperature trends, and the resulting ecological and social impacts. Understanding these concepts is essential for evaluating environmental policies and practices aimed at mitigating climate change.
In practice exams and competency assessments, questions related to this topic often focus on interpreting data from climate models, recognizing the effects of climate change on biodiversity, and analyzing case studies of affected ecosystems. A common pitfall is misinterpreting the correlation between human activities and climate change impacts, leading to incorrect conclusions about causation. Test-takers should pay close attention to the wording of questions, as they may include distractors that could lead to confusion.
A practical tip often overlooked is the importance of staying updated on current climate data and trends, as this can enhance understanding and application of the concepts in real-world scenarios.

Climate change threatens biodiversity by altering habitats, disrupting ecosystems, and increasing extinction rates among vulnerable species (College Board AP CED).
- 11
What is a feedback loop in the context of climate change?
A feedback loop in climate change refers to processes that amplify or diminish the effects of climate change, such as the melting of ice reducing albedo, leading to further warming (College Board AP CED).
- 12
What is the impact of climate change on agriculture?
Climate change can affect agricultural productivity through altered precipitation patterns, increased pests, and extreme weather events, impacting food security (College Board AP CED).
- 13
How does melting permafrost contribute to climate change?
Melting permafrost releases stored methane, a potent greenhouse gas, which exacerbates climate change (College Board AP CED).
- 14
What is the relationship between climate change and extreme weather events?
Climate change is linked to an increase in the frequency and intensity of extreme weather events, such as hurricanes, droughts, and floods (College Board AP CED).
- 15
What role do fossil fuels play in climate change?
Fossil fuels are the largest source of anthropogenic greenhouse gas emissions, significantly contributing to global warming (College Board AP CED).
- 16
What is the impact of climate change on water resources?
Climate change affects water resources by altering precipitation patterns, leading to droughts in some areas and flooding in others, impacting water availability (College Board AP CED).
- 17
How does climate change affect human migration?
Climate change can lead to displacement and migration as people seek to escape areas affected by extreme weather, sea-level rise, and resource scarcity (College Board AP CED).
- 18
What is the role of renewable energy in mitigating climate change?
Renewable energy sources, such as solar and wind, help reduce greenhouse gas emissions by providing alternatives to fossil fuels (College Board AP CED).
- 19
What are the social implications of climate change?
Climate change can exacerbate social inequalities, as vulnerable populations often face the greatest risks and have the least capacity to adapt (College Board AP CED).
- 20
What is the significance of the IPCC reports?
The Intergovernmental Panel on Climate Change (IPCC) reports provide comprehensive assessments of climate science, impacts, and mitigation strategies, guiding global policy (College Board AP CED).
- 21
What is the impact of climate change on ocean currents?
Climate change can disrupt ocean currents, which play a critical role in regulating climate and weather patterns globally (College Board AP CED).
- 22
How does climate change influence the frequency of wildfires?
