With reference to a coastal environment at a local scale, assess the predicted impact of climate change upon the landscape. [20 marks]
Worked Solution & Example Answer:With reference to a coastal environment at a local scale, assess the predicted impact of climate change upon the landscape - AQA - A-Level Geography - Question 3 - 2020 - Paper 1
Step 1
Identify impacts of climate change on coastal environments
Answer
Climate change primarily affects coastal environments through rising sea levels and increased frequency of extreme weather events. This results in flooding, coastal erosion, and habitat destruction. Specifically, areas like Great Yarmouth face the risk of inundation as sea levels have risen due to melting ice caps and thermal expansion of the oceans.
Step 2
Assess specific local examples of climate impacts
Answer
In Great Yarmouth, the historical significance of the area, such as its proximity to the Norfolk Broads and the River Yare, exacerbates the impact of climate change. The area has experienced notable floods, particularly in 2006, suggesting vulnerability. Furthermore, with the beach erosion and the effect of storms, structures like the cliffs and habitats are increasingly at risk.
Step 3
Discuss response strategies to mitigate effects
Answer
To combat these issues, sustainable coastal management practices have been suggested. Initiatives like the Government-funded Pathfinder Project aim to understand and mitigate risks, emphasizing the importance of evidence-based strategies. Measures such as managed retreat and the construction of sea walls may be necessary to safeguard the coastline and protect local communities.
Step 4
Evaluate potential long-term predictions
Answer
Long-term predictions show that if current climatic trends continue, local landscapes will undergo significant changes. Regions like Great Yarmouth may see a loss of beach areas and increased risk of coastal flooding, detrimentally impacting local economies reliant on tourism and fishing. Evaluation of ongoing climate actions and community preparedness will be crucial in adapting to these challenges.
