NASA "Our planet is evaporating" (Video)



For a moment, let's not debate what the cause is behind the increased trend in wildfires and lands now exposed to this threat. Rather lets acknowledge that this trend is not good because not only of the explicit life-threatening dangers posed, but also because it places arable farmlands and wildlife in greater jeopardy. This is not good economics by any means. (Remember, Bugonomics last month?)

Many years ago, CPA firms would claim their advisory leadership advantage and unique value proposition was through "getting behind the financial statements numbers". Perhaps economists and policy-makers should steal a page from the CPAs' slogans book and get behind the GDP numbers - because when they do, they should discover that real economic capacities are burning up or evaporating. These are the physical capacities that will drive the GDP numbers of tomorrow. Neat idea?

Maybe this same approach could have perhaps been helpful with urban management too - Detroit, New Orleans, Newark and so forth and thus slowing the evaporation of such centres. 

Hmm - "getting behind the numbers" - it has a catchy ring to it.

Projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or 'fire weather'. An average increase of 1 mm/day over the whole year is a big change, one we can put in specific terms: We consider a 1 mm/day increase in PE to be an 'Extreme' event for fires, something like 2012 in Colorado. By these projections, fire years like 2012 would be the new normal in regions like the western US by the end of the 21st century. Graphic: NASA
