The Colorado Flood: On Risk + Climate – What we can learn from natural disasters.

As some of the readers of this blog will know I recently moved from London to Nederland, Colorado (a small town outside of Boulder – where I work).

Still we reminded ourselves that Nederland was lucky relative to many of our neighbours.

Even more serious environmental disasters are in process as oil, gas and toxic fracking chemicals (including known carcinogens and endocrine disruptors) spills have become apparent at the site of at least 10 of the hundreds of fracking sites in the flood zone.
