The IELTS Reading section is a critical part of the exam, and understanding how to tackle complex texts can significantly boost your score. Over the years, the topic of climate change and its impacts on global water resources has frequently appeared in the IELTS test. Given its relevance and urgency, it is likely to feature prominently in future exams as well. This article aims to provide you with a comprehensive reading sample on “How does climate change impact the distribution of global water resources?”, along with practice questions, answers, and essential vocabulary and grammar insights to help you excel.
Reading Passage: The Impact of Climate Change on Global Water Resources (Medium Text)
Climate change has become a significant global issue, impacting various environmental systems, including water resources. The rising temperatures, fluctuating precipitation patterns, and increasing frequency of extreme weather events are all factors that influence the availability and distribution of freshwater resources around the world.
Changes in Precipitation Patterns
Alterations in rainfall periods and intensity are one of the most immediate impacts of climate change. Some regions are experiencing prolonged droughts, while others face unprecedented flooding. For instance, southern Africa and southeastern Australia have seen reductions in annual rainfall, leading to severe water scarcities. Conversely, North America and parts of Europe are contending with increased torrential downpours, exacerbating flood risks.
Melting Ice Caps and Glaciers
The melting of polar ice caps and glaciers is another major consequence of rising global temperatures. Glaciers in the Himalayas, Andes, and Rockies are retreating at alarming rates. The meltwater from these glaciers contributes significantly to river systems that millions of people depend on for drinking, agriculture, and industry. However, as the glaciers diminish, so does the predictability and availability of water from these sources.
Rising Sea Levels
Rising sea levels pose another threat to freshwater resources. As sea levels rise, seawater intrusion into groundwater supplies becomes a critical issue, especially for coastal communities. Countries like Bangladesh and small island nations in the Pacific are particularly vulnerable to this encroachment, threatening the supply of potable water and agricultural viability.
Impact on Water Quality
Climate change also affects water quality. Warmer temperatures can lead to the proliferation of harmful algal blooms in freshwater bodies, making water unsafe for consumption. Increased runoff from heavy rains can carry pollutants into rivers and lakes, further degrading water quality and posing risks to human health and ecosystems.
