  1. Please label the axis’ on your graph. That is the proper way to make a graph.

    1. DJ: Agree, although I didn’t make the graph, I lifted it from the PwC report, so wasn’t able to easily make changes to their graph. Sorry.

    What we are really talking about here is the thermal stability of the planet in our burning of fossil fuel energy. After 350 parts per million of carbon in our upper atmosphere, that stability comes into question… today, as you read this we are at 390 parts per million and raising. Living systems are sensitive to very small changes. E.g., if your child’s temperature goes up a couple degrees you’ve got a low-grade fever on your hands; if it goes to say 103, you’re likely headed to the Emergency Room. ~ Right now our planet has a fever, and what is already built in this century is gonna’ give us successive major weather events, and a 4 degree average raise in the world’s temperatures may be unavoidable at this point. The cumulative effects play out for along time ~ even if we stopped Carbon burning today, we are building feedback loops and possibly unstoppable processes like loss of polar ice and even more carbon release from methane gas exposure from thawing of previously trapped carbons. ~ Natural gas maybe our only window to give us time to change, though fracking has its own problems… In short, it is past time for us to stop pouring more carbons into our atmosphere. The problem in the century we are now in and in the ones shortly to come are not gonna’ be about short term profits, but rather that it takes only a few degrees of change in global average to effectively knock our kind out of the equation…
