Carbon Dioxide Level Set To Reach New Milestone

The Scripps Institute of Oceanography reports that the level of carbon in the atmosphere is ready to pass a milestone to 400 parts per million.  There is nothing magic about the milestone and it may recede during the spring as plants absorb more carbon.  It is a warning, however, that the industrial revolution may have created great wealth at the expense of our environment. It is estimated that the level of carbon dioxide in the atmosphere was around 290 parts per million prior to the industrial revolution.
