Study Notes
Natural Causes of Climate Change
- Solar energy: Earth receives more solar energy due to the sun's energy output.
- Earth's tilt: The Earth's tilt changes over 41,000 years, varying from 22 to 25 degrees, affecting the amount of solar energy received.
- Volcanic eruptions: Ash and dust in the atmosphere block sunlight, reducing temperatures for months to years.
Greenhouse Effect
- Greenhouse gases (CO2, methane, ozone): These gases trap some solar energy, warming the Earth. This is a natural process.
- Increased greenhouse gases: Higher concentrations of greenhouse gases lead to greater warming, potentially causing climate change.
- Energy balance: The balance between incoming and outgoing energy changes with greenhouse gas concentrations.
Human Causes of Climate Change
- Increased CO2: Human activities (e.g., energy production, transportation, industry, agriculture, and waste) release more CO2 into the atmosphere.
- Temperature increases: From 1948-2013, average temperatures in Canada rose by 1.6°C, likely due to increased greenhouse gases.
Adapting to Climate Change
- Replace fossil fuels: Transition to alternative energy sources.
- Reduce energy consumption: Decrease personal energy use through efficiency measures.
- Plant trees: Trees absorb CO2, helping mitigate climate change.
- Develop climate-resilient crops: Growing crops suited to changing climate conditions.
- Strengthen health services: Provide resources to deal with extreme weather events.
- Protect water sources: Maintain access to safe water supplies.
- Create green spaces: Increase urban green spaces to help regulate temperature.
