As we said yesterday, we got so many strong submissions this month that picking winners was extremely difficult. Many excellent images had to remain in what some submitting artists have affectionately dubbed “the slush pile” (a term that seems particularly apt this month). Nadja is particularly partial to the first two in this series by Barry Bruner - but really, there are many worth clicking through for. One thing to keep in mind for this contest: though on the blog we give a theme, when we look for winning images, we look for an image that contains the theme within itself. That is to say, to make a good cover, the stand alone image needs to be able to conjure the idea of global warming without surrounding text. Thank you to all the artists who took the time to submit - we look forward to hearing which images you liked and why. Stay cool!
