Amidst polls showing a decline in concern over the impacts of global warming, perhaps it is time to revisit the basics.

The ability of human carbon emissions to warm the planet was first theorized over 100 years ago, near the beginning of the industrial age. Since that time, the theory has been reinforced by countless studies from around the world. However, the subjects of anthropogenic global warming and climate change are complex. It is easy for us to lose sight of the bigger picture when facing a season of cold winter days.

So, the following series of videos seeks to provide an understanding of the fundamentals of the anthropogenic global warming theory while taking a look at the last 30 years of satellite observation of our planet and how various natural influences relate to the impact from mankind.

Section 1: The Greenhouse Effect

How important is the greenhouse effect, and how important is carbon dioxide to that effect?


Section 2: The Human Impact

What impact can humans possibly have on our global environment?

Section 3: A Global Balancing Act

What differentiates various influences on the climate, and how does the planet react to these influences? How are human carbon emissions critically different than their natural counterparts?

Section 4: Current Conditions

How is the climate reacting to the current influences on it, and how is this reaction reflected around the world?

Section 5: Inertia, Feedback, & Tipping Points

Even if you’re not concerned with current conditions, why is action related to curbing carbon emissions still urgently needed?
