Access numerous carbon footprint calculators and useful tips on how to reduce your footprint here. This list of Web resources was compiled by IGLO (International Action on Global Warming). IGLO raises worldwide public awareness about global warming and the particular ways that the Polar Regions profoundly influence the Earth’s climate, environments, ecosystems, and human society.
This video on the Grand Illusions website shows all the large aircraft flights in the world, over a 24 hour period. Each aircraft is shown as a little yellow dot. The video has been speeded up, so that 24 hours takes only 2 minutes on your computer screen!
The video would be an excellent way of introducing how air travel might be a contributory factor to Climate Change.
