Natural Cycles and Climate Change [video]

Posted on October 28, 2012


Natural cycles, you say?  Then you’ll want to know about El Niño and La Niña, about the affect on climate of volcanic eruptions and solar cycles.  Scientists have carefully studied all the natural influences on Earth’s climate and found out that by themselves, they don’t suffice to explain our current warming.  Until the human-caused increase of greenhouse gases in our atmosphere is taken into account, only then does the math add up.

What is happening to the climate now is not natural and not part of any cycle.

The following video, the seventh in a series of seven produced by the National Research Council, the working arm of the US National Academy of Sciences, addresses the question of natural cycles and climate change.

The first six videos may be found here:

  1. What is climate?
  2. Is Earth Warming?
  3. Greenhouse Gases
  4. Increase Emissions
  5. Climate Forcings
  6. The Sun and Climate Change
