The Chemistry of  CO2: Carbon Dioxide

Date : 11/18/2011

Clip Length : 

This NBC Learn video explains and illustrates the molecular structure of CO2; how the bonding of the carbon and oxygen molecules illustrates the Octet Rule, or Rule of 8; carbon dioxide and carbonation; the role of CO2 in the Earth's atmosphere; and how changing levels of CO2 can affect the temperature on the Earth's surface, including the oceans.

Black Carbon

Date : 03/11/2011

Clip Length : 00:06:07

Black carbon, composed of tiny particles of soot, is produced whenever organic substances like fossil fuels, firewood or coal is incompletely burned. These particles are polluting the air and causing serious health and environmental concerns for people around the world. "Changing Planet" is produced in partnership with the National Science Foundation.

Thawing Permafrost

Date : 03/25/2011

Clip Length : 00:06:47

Because of a warming atmosphere, permafrost -- the frozen ground that covers the top of the world -- has been thawing rapidly over the last three decades. But there is cause for concern beyond the far north, because the carbon released from thawing permafrost could raise global temeratures even higher. "Changing Planet" is produced in partnership with the National Science Foundation.

As higher amounts of carbon dioxide become absorbed by the oceans, some marine organisms are finding it's a struggle to adjust. "Changing Planet" is produced in partnership with the National Science Foundation.

Survival of Trees

Date : 09/23/2011

Clip Length : 00:05:22

Dr. Joy Ward at the University of Kansas is looking at how rising levels of carbon dioxide in the atmosphere may be impacting trees around the world and even causing them to adapt. By looking at ancient tree specimens from the Ice Age, Ward is able to see how trees in the past have adapted, helping her understand how trees may adapt today and in the future. Changing Planet is produced in partnership with the National Science Foundation.

Clip Length : 00:02:12

In 2008, the journal Science reports that the production of biofuels such as ethanol and soybean biodiesel actually doubles instead of reduces carbon dioxide emissions.
