Yes.
The distinction I need to always make, and this was even in the national climate change process, is that people confuse actions--the things individuals and businesses do to reduce greenhouse gases--with policies. The policies need to be immediate--there are some delays, which Bob has legitimately pointed out--and then the actions happen incrementally, over time.
Quite often I get frustrated. People will say, oh, the actions are going to happen over time, so we'll implement the policy later. The point is, no, the actions don't even start until the policy is there.
You also asked about the intensity. That's why you need that graduated signal, to say to people, look, it's going to get more expensive to keep using the atmosphere in this way. We want everyone to know that, because that really helps business in thinking about the research and development and the investment dollars as they head down the road.
