Practice Reading Passage

Effects of Climate Change on Global Water Levels

Climate change has emerged as one of the most profound challenges of our time, with significant impacts on global water levels. Rapid alterations in temperature and precipitation patterns, coupled with the melting of ice caps and glaciers, have led to fluctuating sea and freshwater levels with far-reaching consequences.

Rising Sea Levels

One of the most apparent effects of climate change is the rise in sea levels. As global temperatures increase, polar ice caps and glaciers melt at unprecedented rates, contributing to higher ocean levels. According to the Intergovernmental Panel on Climate Change (IPCC), sea levels have risen by about 8-9 inches (20-23 cm) since the late 19th century, with an accelerating trend observed in recent decades. This phenomenon threatens coastal communities, leading to increased flooding, erosion, and salinization of freshwater sources.

Rising Sea Levels

Changing Freshwater Availability

In addition to rising sea levels, climate change significantly alters the availability and distribution of freshwater. Changes in precipitation patterns can cause some regions to experience severe droughts, while others may face intense and frequent flooding. The shift in weather patterns disrupts the hydrological cycle, affecting water supply for drinking, agriculture, and industry. For instance, reduced snowpacks in mountainous regions diminish the freshwater availability during warmer months, impacting water resources and ecosystems.

Impact on Marine Ecosystems

The fluctuation of global water levels also poses a threat to marine ecosystems. Rising sea levels and changing temperatures can lead to the destruction of vital coastal habitats such as mangroves, salt marshes, and coral reefs. These ecosystems serve as crucial breeding grounds for marine species and act as natural barriers against storms and floods. The loss of these habitats not only jeopardizes biodiversity but also diminishes the natural protection provided to coastal communities.
