Understanding Global Warming: Causes, Evidence, and Future Implications

This introduction to global warming explores its causes and evidence. It addresses the role of greenhouse gases, such as carbon dioxide and methane, contributed by industrialization, deforestation, and agriculture. The greenhouse effect explains how heat is retained in the atmosphere, leading to rising temperatures. The text also discusses the natural aspects of climate change while stressing the anthropogenic factors driving current trends. Finally, it reflects on what the future may hold if action is not taken to mitigate this pressing global issue.

  17. Reflected by the atmosphere into space. Solar Energy Heat lost to space GREENHOUSE GASES Heat is retained by greenhouse gases and warms the atmosphere- Global Warming Global Warming Earth radiates heat. Solar energy heats Earth. Greenhouse effect

  18. Greenhouse gases increase. Farming rice and cattle releases methane. GREENHOUSE GASES Deforestation means less Carbon Dioxide is taken in, some trees are burnt releasing Carbon Dioxide. Burning fossil fuels releases Carbon Dioxide. Global Warming More heat is trapped, warming the Earth. Human impact...
