Final answer:
Global warming refers to the increase in average temperatures on Earth due to greenhouse gases. Burning fossil fuels like coal contributes to global warming. The negative effect of continued global warming is the melting of polar ice caps and rising sea levels.
Step-by-step explanation:
Global Warming and its Effects
Global warming refers to the long-term increase in average temperatures on Earth due to the buildup of greenhouse gases in the atmosphere. These gases trap heat from the sun and cause the Earth's temperature to rise, leading to changes in climate patterns.
One major human activity contributing to global warming is the burning of fossil fuels such as coal, oil, and natural gas for energy production. This releases large amounts of carbon dioxide, a potent greenhouse gas, into the atmosphere. Carbon dioxide traps heat and leads to the warming of the planet.
Continued global warming can have numerous negative effects on the environment. One such effect is the melting of polar ice caps and glaciers, leading to a rise in sea levels. This can result in coastal flooding, lost habitats for various species, and the displacement of coastal communities.
