A History of Earth’s Climate [11:19]

Description

To fully understand the current issue our world is facing with man-made climate change, or global warming, we need to understand a bit about Earth’s climate history.  This video discusses the history and major causes of Earth’s cycling between Greenhouse and Icehouse climates.  The video ends with data and discussions about our current situation and the anti-Global Warming claim that we’re actually heading toward an ice age and that the Earth is cooling.

Discussion Questions

  • What are some of the causes of change in global climate?
  • Are we actually in a period of cooling, entering a global ice age?
  • If such changes are natural, does that mean the current changes we’re witnessing are natural too?

Keywords: nature, global warming, climate change, environmentalism,
