Climate change, a consequence of global warming, (30) ______, particularly the burning of fossil fuels such as coal, oil, and natural gas. These actions release carbon dioxide, a greenhouse gas, which traps heat in the Earth's atmosphere and leads to an increase in global temperatures. The rise in temperature disrupts the delicate balance of ecosystems and has a range of significant consequences on the planet.
One of the most obvious consequences of climate change is the rising sea level. This phenomenon is linked to the melting of polar ice caps and the expansion of seawater as it warms. As a result, coastal regions are increasingly at risk of flooding, erosion, and the loss of natural habitats.

These events can lead to reduced agricultural productivity, food and water shortages, and the displacement of people and wildlife.
In response to the growing concern surrounding climate change, there has been a shift towards the use of renewable energy sources, which produce fewer greenhouse gas emissions compared to traditional fossil fuels. By using renewable energy, we can help reduce the impacts of climate change and (32) ______.
