Things are different now: Now, however, carbon dioxide has reached levels not seen for at least 3 million years, and fossil fuel emissions have become the dominant driver of the changes to our climate. In a world potentially several degrees warmer than the one that spawned our civilization, we had better ready ourselves for some surprises. This isnt alarmism; its just sensible risk management. Retired US Navy Rear Admiral David Titley, now head of Penn States Center for Solutions to Weather and Climate Risk, pointed out that governments still spend money on defence, despite the declining number of people killed worldwide in war. He told the US Congress that we rightly invest in our security and defence as one component of hedging against unknown or unlikely security risks. Inaction on climate change violates that same fundamental risk-management principle.
