Yes, they would have. To clarify, it's not the business of the IPCC to define what represents dangerous anthropogenic interference or dangerous human interference with the global climate system. That ultimately is a political decision.
There's been a growing constituency begun by the small island states in the EU who say that two degrees is dangerous, and there are a number of other countries that say, well, hold on here--you're talking about stopping everything in its tracks, so let's get a little realistic about this, etc. That still is under negotiation.
If you do want a two-degree world, if that's what your goal is--and that's not been decided yet by the global community--then it would likely require two things. Number one, 25% to 40% reductions by 2020 of 1990 levels on the part of OECD countries, and in 2020 already you're going to be seeing a significant departure from business-as-usual for major developing countries. If it's just going to be OECD doing it alone without developing countries, we won't get anything close to two degrees. Let's be clear about that.
