Of the hottest years on record, nine out of ten have occurred since 1990. Thousands of plant and animal species are already on life support. Hurricanes, floods, droughts, heat waves and forest fires are happening with more regularity and intensity than ever before. And in a matter of decades, some coastal communities could be entirely under water. All because of global warming. All because of the choices we make every day.

Legendary UK broadcaster Sir David Attenborough says we’ve reached a tipping point and that we must act now to save our planet. Through sensible, manageable, and meaningful changes he says we can save planet earth without tossing out our air conditioners and returning to the days of horse and buggies.

Questions for Part One:

1. How are human activities believed to be changing the climate of the planet?
2. How did Global Warming lead to the devastating strength of Hurrican Katrina?
3. The climate of the Earth has always been changing – are the recent changes in climate the same as past changes? What are the differences between natural changes and human=related changes?
4. How is Global Warming affecting the Great Barrier Reef?

Extension:
What do ancient rainforests have to do with the increase of CO2 in today’s atmosphere?
