"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?"

None Like It Hot!

But we are already trying that, and it is not working. The Arctic sea ice is just melting away and the planet is still getting hotter. What will happen when all the Arctic sea ice has melted?

Cheers, Alastair.

Great cartoon.

One of the few geoengineering schemes that might even make sense is a very modest one, Ice911, run by a neighbor of mine, with top-notch advisors like Terry Root and (before his death) Steve Schneider.

The basic idea is to engineer cheap, appropriate, floating materials to cover parts of the Arctic Ocean and raise its albedo to slow the melt, i.e., reduce the ice-albedo positive feedback. Leslie gave an interesting presentation on this at our local town center about a year ago. A worthy cause, I've donated.

Ah, a planet cozy.
