"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?"

Anthropocene Geography

Via Resilience Science, an Andrew Revkin article in the NYTimes about "mapping on the run".
Now, though, the accelerating and intensifying impact of human activities is visibly altering the planet, requiring ever more frequent redrawing not only of political boundaries, but of the shape of Earth’s features themselves.
The images are before and after pictures of the Aral sea. The scale on the ground is hundreds of miles. You may be able to make out a white rectangle at lower left that represents 20 km or about 13 mi.

Images are from the UNEP Atlas of the Changing Earth which is very spiffy in a sobering sort of a way.
