National Geographic: Six Degrees Could Change the World (2007)



Starring: Alec Baldwin Director: Ron Bowman Rating

Product Description
In a special broadcast event National Geographic explores the startling theory that Earths average temperature could rise six degrees Celsius by the year 2100. In this amazing and insightful documentary National Geographic illustrates one poignant degree at a time the consequences of rising temperatures on Earth. Also learn how existing technologies and remedies can help in the battle to dial back the global thermometer

6o Film Notes:

What does the film state about Global Warming at the beginning?









Where are we at in this Six Degrees (Celsius) (~11oF) Global Temperature rise?




















What scenarios are predicted with each degree rise in Global Temperature?

1 degree Celsius


One Degree of Warming

At one degree of warming, the Arctic is ice-free for half the year, the South Atlantic—typically void of hurricanes—experiences coastal hurricanes, and in the western U.S. severe droughts are plaguing residents











2 degree Celsius


Two Degrees of Warming

Polar bears struggle to survive as glaciers increasingly melt away. Glaciers in Greenland begin to disappear, while coral reefs are vanishing.











3 degrees Celsius


Three Degrees of Warming

The Amazon rainforest is drying out and El Niño’s intense weather pattern becomes the norm. Europe repeatedly experiences searing summer heat that has rarely happened before.









4 degrees Celsius


Four Degrees of Warming

Oceans could rise, taking over coastal cities. The disappearance of glaciers may deprive many of fresh water. Northern Canada’s agriculture could boom and a Scandinavian beach could be the next tourism hotspot. A part of Antarctica could collapse, causing water to rise even further.
















5 degree Celsius

Five Degrees of Warming

Uninhabitable zones could spread, snow pack and aquifers feeding big cities could dry up, and climate refugees could run in the millions. Human civilization could begin to break down with this drastic of changes to the climate. The poor would likely suffer the most.






















6 degree Celsius


Six Degrees of Warming

At six degrees, the oceans could be marine wastelands, the deserts could march across continents, and natural disasters could become common events. The world’s great cities could be flooded and abandoned. This could be “the doomsday scenario.”












What are the current carbon dioxide levels and what is the critical point in parts per million?




The McMurry textbook, p 462 Figure 16.3, states the current level (2011) is at 389 ppm. The film was produced in 2007, so has the CO2 level of the atmosphere increased or decreased in the last four years and by how much?
