Natural Factors

• Examples of natural climate change include:

  • Eccentricity - Earth's distance from the sun varying over 100 K years
  • Obliquity - Earth's tilt varying
  • Precession - the Earth wobbling slightly due to it not being a perfect sphere
• Examples of natural climate change include:

  • The sun having sunspots on it which have differing temperatures
• Examples of natural climate change include:

  • Volcanic eruptions' sulfur dioxide reacting with water vapour to form a haze layer which reflects the sun's rays
