Transcript of Global Warming
The result is that the globe has heated up by about one degree Fahrenheit over the past century, and it has heated up more intensely over the past two decades.
If one degree doesn't sound like a lot, consider this: the difference in global average temperatures between modern times and the last ice age (when much of Canada and the northern U.S. were covered with thick ice sheets) was only about 9 degrees Fahrenheit. So in fact one degree is very significant—especially since the unnatural warming will continue as long as we keep putting extra greenhouse gases in the atmosphere. Methods to Help/Contribute At Home: Use Less Energy
Home energy accounts for 21 percent of America's global warming pollution. If we make smart choices, we can cut more pollution than the entire emissions of over 100 countries!
On the Road: Be Efficient
When it comes to global warming, how and what we drive are two of our most powerful choices. Transportation is the biggest source of U.S. carbon dioxide emissions, more than factories or homes.
Neutralize the Rest
Even if you are already driving efficiently and using less electricity, there's more you can do. Buying offsets, or credits, neutralizes what we can't cut.

Episode 4- One Carbon Atom Always Tries to Bond With Its Most Stable Partner, Oxygen. When One Carbon Atom Bonds With Two Oxygen Atoms, They Become CO2. Engineers are Working on Fixing Global Warming, by Figuring Out Methods of Carbon Sequestation. Extra Information All living things contain carbon. Fossil fuels are made up of dead organisms that died millions of years ago under the sea. The pressure turned them into black goo, oil, but their carbon bonds remained. Some Carbon Dioxide can be absorbed by trees and the ocean, but some CO2 can escape into the atmosphere.
