Here is a blog post on this movie on \"Blog or Die\". The author brings out an interesting point based on the chart of the Ice-Ages and the level of Oxygen\/CO2.  The movie presents many facts and draws conclusions. I want to separate out what is fact from what I have questions about. Fact List: Carbon dioxide is a greenhouse gas. That means that CO2 tends to allow light through, but not heat. That's a little like when you leave your car windows up on a sunny day. The light streams in through the windows, but the heat doesn't radiate out through glass as well. There is twice as much CO2 in the atmosphere than there has been at any time in the last 600,000 years. We know this because there are ice core samples taken in the Antarctic. Ice is deposited in recognizable annual layers, and schentists can measure the CO2 in the various layers. There is a strong correlation between the amount of CO2 in the atmosphere and the global temperature. The global temperature can be inferred through the ratio of two isotopes of Oxygen in the ice cores. One can see by looking at a time-series chart that CO2 in the atmosphere tracks temperature.","thumbnail_url":"http:\/\/images.amazon.com\/images\/P\/1594865671.01.MZZZZZZZ.jpg"}
