On May 8th 2013 the species reached a milestone that should have perhaps had us freaking out. We hit 400 parts per million of carbon dioxide in the atmosphere. See here (BBC story), here (National Geographic) and here (Gavin Schmidt quote).
Meanwhile, 24 years earlier –
“More specifically, on 8 May 1989, the Office of Management and Budget confirmed that it had altered the Congressional testimony of NASA’s James Hansen, thereby weakening his conclusion that enough was known about the phenomenon to justify immediate action. The Whitehouse defended this action by claiming that it wanted to avoid the appearance of policy disagreements within the Administration. The political fallout from this episode was considerable, not only within the United States but also internationally.”
