"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?"

Uh-Oh

Don't cash those chips in yet.

From the NSIDC:
"Sea ice extent has fallen below the 2005 minimum, previously the second-lowest extent recorded since the dawn of the satellite era. Will 2008 also break the standing record low, set in 2007? We will know in the next several weeks, when the melt season comes to a close. The bottom line, however, is that the strong negative trend in summertime ice extent characterizing the past decade continues."

Note, 2007 has pulled further into the lead in the last week of August. However the bet comes out, though, the serious story is that this year has essentially equalled in practical terms last year's unprecedented decline. Note in the chart above the comparison with the previous ice extent minimum in 2005.

Deltoid has some fun with the denialist camp on this one, starting with some recent unfortunate foolishness on the Register. Comments off, discussion referred to Deltoid please.
