"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?"

Cold Summer, Hot Winter

It's been a coolish summer in much of North America, though, alas, here in Texas, not so much. And while a swath of Texas has been flirting with records for hottest and driest summer, and while Texas is big, it's smaller than the area experiencing unusually cool weather up north. But North America is not, despite appearances, the universe.

Australia has experienced an extraordinarily hot winter. Here's the big picture, from Barry Brook's Brave New Climate blog.

Note the size of that swath of record seasonal warmth. That's not just unusual. That's unusually unusual. (Australia is about the same size as the mainland US, or "lower 48" as the Alaskans would prefer.)

There's much more at Brave New Climate. Check it out, and put that in the hopper, if you'd be so kind.
