Climate Change - Coggle Diagram

- - - - Burning fossil fuels releases Carbon Dioxide, which accounts for 50% of greenhouse gasses. Greenhouse gasses trap warmer air in the atmosphere, causing global surface temperatures to rise.
    - - Accounts for 20% of greenhouse gasses. Larger populations and demand for meat and rice will increase its contribution. As we clear trees for more farmland, we are decreasing the amount of photosynthesis that can occur.
    - - Logging and clearing land for agriculture/roads increases the amount of CO2 in the atmosphere, as less photosynthesis occurs. This means that the more forests we clear, the less photosynthesis can occur.
  - - - Sunspots increase from a minimum to maximum every 11 years. Fewer sunspots were observed during the coldest period ('Little Ice Age', in 16-45-1715). However, solar output has barely changed in the last 50 years. This means that despite global temperatures increasing, the solar activity doesn't have much to do with it.
    - - Volcanic aerosols reflect sunlight away, reducing global temperatures temporarily. This means that in a period with lots of volcanic activity, the global temperatures will be cooler.
    - - The Sun's energy on the Earth's surface changes as the Earth's orbit is elliptical, it's axis is tilted on an angle and the Earth isn't spherical. This means that the closer the Earth's orbit is to the Sun, the warmer the global surface temperatures on Earth are.
