When Erik the Red first arrived in Greenland, the fertile green land was perfect for farming. But within a few centuries the thriving Viking settlements had been wiped out by global cooling. The Little Ice Age is one of many climactic eras that have been scientifically identified. Since about 1850 the earth has been in a warming period.
What is the role of carbon dioxide in warming? The best available records of temperature and atmospheric CO2 over the past 650,000 years indicate that the earth's temperature always rises first, followed by a rise in carbon dioxide. If a warmer earth leads to increased levels of CO2-and not the other way around-can humans' use of fossil fuels be the cause of global warming? Shouldn't this critical question remain open to scientific inquiry?
This video provided an excellent opposing view for An Inconvenient Truth. I used it to set up a debate with my honors class.

This video did help to spur on great conversations about what we are being told in the media and what we hear from the science community. I was eager to share this with my students to help them see other view points, and to help them see the importance of looking beyond popular theory.

This was an excellent, classroom friendly resource in which scientists were allowed to raise critical questions in the climate change debate- great video!
Damian Holmes Social Studies - 9,10 Salem High School, Conyers, GA
I teach a unit in the spring on global warming and climate change. This video is an excellent enhancement to that unit. My students were really intrigued, and it got them thinking. When we start this unit in the spring, I will show it again.
Thanks for your videos!
