Study Notes
Greenhouse Gases
- Greenhouse gases trap outgoing heat, increasing temperatures.
- Anthropogenic climate change threatens the greenhouse effect.
- Naturally, Earth's temperature is 15°C without GHG; without it, it would be -20°C.
- Human activities have increased atmospheric CO2 by 50% since the 18th century.
- CO2 levels are now 150% of their 1750 value.
- This imbalance affects weather and climate systems, resulting in climate change.
Greenhouse Gases and their Impact
- Carbon Dioxide (CO2) accounts for 75% of emissions. Released by burning fossil fuels.
- Methane (CH4) is 84 times more harmful than CO2 over two decades. From agriculture (livestock), natural gas, and landfills.
- Nitrous Oxide (N2O) is 264 times more harmful than CO2 over 20 years. From agriculture (fertilizers) and burning fossil fuels.
- Chlorofluorocarbons (CFCs) are industrial gases, used in refrigerants, solvents, and spray cans.
Consequences of Rising Greenhouse Gas Levels
- Polar ice sheets are melting, raising sea levels, threatening coastal regions.
- Warmer temperatures lead to more intense storms, flooding, droughts, and heatwaves.
- Disruptions to agriculture, water supplies, and food security.
- Urban areas are more vulnerable to air pollution and smog.
- Increased respiratory diseases like asthma and lung cancer.
- Risks of a disastrous change in the climate that may make the planet uninhabitable.
Deforestation
- Forests are vital for our planet, absorbing CO2 (carbon dioxide).
- Deforestation and forest degradation release stored carbon into the atmosphere.
- 80% of deforestation is for livestock farming.
- Deforestation worsens climate change, making extreme events worse (e.g., California wildfires).
The Sun and Global Temperature
- Current global warming is not explained by solar irradiance.
- The Sun's natural 11-year cycle has not led to an increase in global temperature since 1880.
The impact of Animal Agriculture
- Animal agriculture contributes significantly to greenhouse gas emissions, with 15% of global emissions.
- Bovine produce the most methane, over 25 times more potent than CO2 short-term.
- Livestock farming is responsible for 42% of agricultural emissions in the U.S.
- Meat consumption is a major factor regarding climate change since it contributes to environmental damage.
Rising Sea Levels
- Sea levels have risen by 24 cm since 1880 (an average of 3.3 mm per year).
- Continued increases in temperature will lead to more rapid rises in sea levels by up to 1.8 meters.
- Melting ice from Greenland and Antarctica would result in a 66-meter rise in sea levels.
