• What is some evidence for climate change to occur naturally?

  Sun spots - Dark spots on the sun called sun spots. They increase the amount of energy the earth receives from the sun.
• What is some evidence for climate change to occur naturally?

  Volcanic eruption - volcanos release large amounts of dust containing greenhouse gases. This results in blocking sunlight meaning cooler global temperatures.
• Carbon dioxide is released into the air when we burn fossil fuels such as coal, oil or gas.
• Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and fluorinated gases.
• What types of countries are most responsible for climate change?

  ACs - while they usually have the lower populations, they use a lot more materials than LIDCs or EDCs.
