Film: Six (Celsius) Degrees Could Change the World (1 hr 35 min)
1.) When scientists talk about a change of 6C globally they are not referring to fluctuations in daily temperatures but to a global average change. What were conditions like when the globe’s average temperature was 6C cooler than today? The Earth was in the grip of an Ice Age around 18 000 years ago.
2.) How many parts per million of carbon dioxide in our atmosphere is considered to be a dangerous level? 400 ppm. What level are we currently at?
3.) What would the world look like if it were 1C warmer?
Ice free northwest passage for half the year, flooded cities in Asia (Bengal), hurricanes, severe drought affecting food production, emergence of new deserts, etc.
4.) How are warmer temperatures affecting the migration of crops? Champagne region of France is becoming too warm for traditional champagne grapes, so they are starting to grow them in England, along with olive trees.
5.) What is involved in the carbon footprint a common product such as a cheeseburger? All the energy consumed to make up the component parts of the cheeseburger and the greenhouse gasses produced as a result= the feedstock for cattle, growing lettuce, wheat for bun, milking the cattle, processing milk for cheese, and processing cattle for meat, trucking (transporting) the various parts, keeping the meat cold, plus methane gas produced by the cattle
6.) So, what is the carbon footprint of a cheeseburger in the US?
200 million metric tones, more than all the SUV’s in the United States
7.) How might an increase of 2C affect the planet?
Rapid changes in the biosphere, especially marine life of the oceans, dying off of coral reefs, flooding of island states, melting of Greenland’s glaciers, etc.
8.) What significant ocean system could break down that could magnify the warming effect? Carbon sink provided by tiny sea creatures that absorb carbon dioxide from which they build...
