We've used the most effective methods to increase the levels of CO 2 in our atmosphere burning coal oil and natural gas chopping down forests and surprisingly making cement in some respects 400 PPM is just an arbitrary figure an attractively round number like the 4 minute mile or the 7000000000 mark for world's population but it indicates that we've reached a new phase of our experience ...
