"System change is now inevitable. Either because we do something about it, or because we will be hit by climate change. '...

"We need to develop economic models that are fit for purpose. The current economic frameworks, the ones that dominate our governments, these frameworks... the current economic frameworks, the neoclassical, the market frameworks, can deal with small changes. It can tell you the difference, if a sock company puts up the price of socks, what the demand for socks will be. It cannot tell you about the sorts of system level changes we are talking about here. We would not use an understanding of laminar flow in fluid dynamics to understand turbulent flow. So why is it we are using marginal economics, small incremental change economics, to understand system level changes?"

It's 3 C

The global sensitivity to CO2 doubling appears to be pretty close to 3 C. Stop the presses.

The global equilibrium temperature sensitivity to CO2 forcing is really starting to look like we have it down. Can we move the conversation on to more appropriate questions?

No, I suppose not...

Welcome back to the blogosphere.

As for the question, so long as influential scientists are pushing the "Values substantially higher than 4.5°C cannot be excluded..." meme, ISTM there is still work to be done :-)
