Easy to read climate book?

[Henrik Selin]

A student asked me the following question: I would like to purchase a 
book that explains the specific effects of global warming (for 
instance, case studies on species). I am hoping to find a book that 
is easily read and includes photographs, something that I will be 
able to share with friends and family and use as a sort of coffee 
table book to explain global warming effects to people who don't 
understand the science of it.

Any ideas and suggestions?
