Due to its pertinence, it is highly likely that candidates may encounter similar topics in future exams.
This article provides a comprehensive Reading passage along with an array of IELTS-style questions and detailed answer explanations, aimed at aiding learners in their preparation for the IELTS Reading test.
Reading Passage: Impacts of Climate Change on Water Resources
Climate change significantly affects global water resources, posing substantial risks to both natural ecosystems and human communities. As global temperatures continue to rise, the hydrological cycle is disrupted, leading to a complex array of consequences. This passage examines some critical impacts of climate change on water resources, emphasizing various aspects such as water availability, quality, and ecological balance.
Increasing Frequency of Extreme Weather Events
One of the most visible impacts of climate change is the increasing frequency of extreme weather events, including heavy rainfall, storms, and prolonged droughts. These events can lead to severe water scarcity or flooding, affecting water availability for agriculture, industry, and domestic use. Changes in precipitation patterns have led to regions experiencing either intense rainfall or prolonged periods of drought, both of which can have devastating effects on water supply.
Melting Glaciers and Ice Caps
Glaciers and ice caps serve as significant freshwater reserves. However, rising global temperatures have accelerated the melting of these ice formations, leading to a reduction in freshwater availability. The melting glaciers result in rising sea levels and the alteration of freshwater flows into rivers and lakes, impacting both human and ecological water needs.
Groundwater Depletion
Groundwater resources are increasingly under stress due to over-extraction and reduced recharge rates. With less precipitation infiltrating groundwater reserves, the pressure on these critical water sources intensifies. Many communities worldwide rely on groundwater for drinking and irrigation. The depletion of this resource can lead to severe consequences, including land subsidence and the loss of fertile land.
Water Quality Degradation
Climate change impacts not only water quantity but also water quality. Increased temperatures can lead to higher rates of water evaporation, concentrating pollutants in smaller volumes of water. Moreover, extreme weather events can result in the contamination of water supplies through runoff that carries pollutants from agricultural fields, urban areas, and industrial sites. This deterioration in water quality poses significant health risks to humans and aquatic life.
Ecological Impact
Water ecosystems are particularly vulnerable to changes in water flow and quality. Altered patterns of precipitation and temperature can disrupt the life cycles of various aquatic species, affecting biodiversity and ecosystem health. Changes in water temperature and chemistry can influence the reproduction and survival rates of fish and other aquatic organisms, ultimately impacting the entire food web.
