I found this photo of Houston in a story on io9. The story, by Annalee Newitz, describes how ozone in the atmosphere, while bad for the atmosphere, does create some beautiful sunsets.
I sense that Ms. Newitz wrote with a certain degree of irony. However, speaking as an economist, I must insist that all efforts to mitigate global warming be immediately placed on hold until we have done further research. We can't be taking rash actions without knowing all the facts, and we won't know all the facts until we know the extent to which utility is being increased due to the ability of pollution to improve sunsets. Blindly stumbling forward without further studies would be irresponsible, and constitute a craven surrender to the enviro-fascist conspiracy. If anyone would like, I could provide a graph with some curves and numbers to prove my point.
Thanks to io9 for the story, and thanks to eschipul for the photo.
