"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?"

Is there an on-line betting pool for this season?

I doubt if we have enough thick ice left for ringed seals to successfully rear young. This will leave polar bears hungry. I doubt if we have enough ice flows over shallow water for walrus to rear their young. . . . I think that over the next 5 years we will see a shocking loss of Arctic wildlife -- Even if we do not set any new records this year.
