"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?"

Bastrop Fires Subside

I think Ron was joking, but in fact some of the success in controlling the Bastrop fire was actually due to informal, volunteer contributions.

Firefighters are mopping up the remnants of a blaze that tore through Bastrop State Park this week. All but 100 acres of the park were blackened by wildfire, but crews managed to save many historic Depression-era buildings.

...

Firefighters worked 30 hours without rest to limit damage by the fire. They saved cabins and other structures by spraying them with water and carving fire lanes around them with bulldozers loaned to the agency by volunteers.
Here's (hopefully) the final footprint of the Bastrop fire.


(NASA explains the 'LEUCKE', which is coincidentally used to calibrate their image resolution.)
We also made an empirical estimate of spatial resolution for lower contrast vegetation boundaries. By clearing forest so that a pattern would be visible to landing aircraft, a landowner outside Austin, Texas (see also aerial photo in Lisheron 2000), created a target that is also useful for evaluating spatial resolution of astronaut photographs. The forest was selectively cleared in order to spell the landowner's name 'LUECKE' with the remaining trees (figure 10). According to local surveyors who planned the clearing, the plan was to create letters that were 3100 ´ 1700 ft (944.9 ´ 518.2 m).
