Study Notes
Greenhouse Gases and Their Impact on Climate Change
- Carbon dioxide levels in the atmosphere have not exceeded 300 ppm in the last 800,000 years, but have risen significantly due to human activities since the Industrial Revolution.
- Methane contributes 4 to 9 percent to the greenhouse effect, produced by ruminant digestion, slow organic matter decomposition, and human activities like natural gas extraction and waste treatment.
- Nitrous oxide, 300 times more potent than carbon dioxide, is produced from fuel burning and wastewater treatment.
- Water vapor, a significant greenhouse gas, contributes 35-70 percent to the greenhouse effect and amplifies the effect of other greenhouse gases.
- Ozone, with 25 percent potency of carbon dioxide, has increased at ground level due to human activities, affecting health and vegetation.
- Fluorinated gases, solely from human activities, are potent greenhouse gases causing ozone layer depletion.
- Oxygen and nitrogen, though not greenhouse gases, play crucial roles in sustaining life and are impacted by human activities, affecting climate.
- Argon, making up 0.9% of air volume, is not a greenhouse gas but affects heat transfer.
- Greenhouse gases are essential for Earth's habitability, regulating temperature and protecting from harmful UV radiation.
- The enhanced greenhouse effect, caused by industrialization and fossil fuel use, has led to a significant increase in carbon dioxide levels and subsequent environmental impacts.
- Fossil fuels are the most widely used energy sources, contributing to the enhanced greenhouse effect.
- The enhanced greenhouse effect leads to ocean warming, sea level rise, melting glaciers, habitat loss, and altered precipitation patterns, impacting ecosystems and species.
