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.
