James Hansen and many other scientists have been working on the matter of climate change for a long time. Climate change is very complicated, but the evidence is that we are facing change that has not been seen in MILLIONS of years. We are not facing a 100 year storm, but a disruption that happens only a few times in the life of the planet. This Hansen report should be a wake up call to decision makers. It further justifies the MDIA rethink of how we do metrics about all decision making and the accounting for risk.
