What is Global Warming? Essay on Global Warming

What is Global Warming? Global warming occurs when the average global temperature rises as a result of increased greenhouse gas emissions. Greenhouse gases such as carbon dioxide, methane, and ozone capture sun energy. Furthermore, the greenhouse effect is increased when polar ice caps and sea ice melt. Sea levels are rising due to the melting of the polar ice caps. Furthermore, the greenhouse effect is increased when polar ice caps and sea ice melt. This is because ice reflects 50 to 70% of the sun's rays into space, whereas when there is no ice, solar radiation is absorbed. Seawater reflects only 6% of the sun's light back into space. Greenhouse gases aren't always dangerous. In reality, life on Earth depends on the greenhouse effect. Without this effect, the sun's rays would be reflected back into the atmosphere, freezing the earth and making life impossible. However, when large amounts of greenhouse gases are trapped, catastrophic effects result. A number of thin
