Causes of Climate Change
There are three types of climate change:
The normal, long-term climate change, which has been happening forever, is due to fluctuations in Earth's movement around the Sun, plus it's tilt and wobble.
Then there is enhanced climate change or anthropogenic climate change – the recent, very rapid warming of Earth due to the influences of people.
Finally, there are short-term perturbations in Earth's climate systems caused by sun-spot activity, volcanic eruptions and phenomena like El Nino and La Nina. However, since climate is a 30-years average of conditions, these aren't truly climate changers, but part of the normal changes we experience here on Earth.
