Study Notes
Greenhouse Effect
- Human activities are driving up the Earth's temperature, primarily due to the greenhouse effect.
- Greenhouse gases like water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons trap heat, similar to how a greenhouse traps heat.
- The more greenhouse gases in the atmosphere, the more heat gets trapped, strengthening the greenhouse effect and leading to increased global temperatures.
Human Activities and CO2 Increase
- Burning fossil fuels has significantly increased the amount of carbon dioxide (CO2) in the atmosphere.
- CO2 levels have risen by more than a third since the Industrial Revolution.
- The rapid increase in greenhouse gases has resulted in a substantial rise in global temperatures.
Climate Change Consequences
- The effects of climate change are widespread, impacting various aspects of the planet, including:
- Oceans: Ice sheets are melting, causing sea levels to rise and flooding coastal regions.
- Weather: Climate change results in more extreme weather patterns, including intense storms, floods, heavy snowfall, and longer, more frequent droughts.
- Food Sources: Growing crops is becoming more difficult due to changing weather conditions.
- Health: Increased air pollution from smog, particularly in urban areas, is linked to health problems like asthma, heart disease, and lung cancer.
Combating Climate Change
- While humans are the primary drivers of climate change, they can also play a significant role in mitigating its effects.
- Replacing fossil fuels with renewable energy sources, such as solar and wind, can significantly reduce greenhouse gas emissions.
- Transitioning to renewable energy can help prevent some of the worst consequences of climate change.
