Global Climate Change

It's not a hoax, nor is it fake news. Climate is a measurable phenomenon. We know Global Climate Change is happening. Can we now get over the arguing and actually start doing something about it?! And, as of December 2020, there might just be room for optimism . . .

Causes of Climate Change

There are three types of climate change:

  1. The normal, natural climate change, which has been happening forever, is due to fluctuations in Earth's movement around the Sun, plus its tilt and wobble.

  2. Then, there are short-term perturbations in Earth's natural climate systems caused by sun-spot activity, volcanic eruptions and phenomena like the El Niño–Southern Oscillation (ENSO) which includes La Niña. 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.

  3. Finally, there is enhanced climate change or anthropogenic climate change – the recent, very rapid warming of Earth due to the influences of people: burning fossil fuels, deforestation, agriculture and trade.
