This is a very successful book, it packs a huge punch in a very small book.  Maslin has been able to reduce extremely complex issues into digestible bite-sized information that anyone can understand and actions to help solve the problems, from individuals to companies and governments.  I would absolutely recommend it, I would only say that he skims over or does not address companies 'off setting' emissions and the problems this causes, the fallout of job/income loss of those countries and communities currently employed in fossil fuel jobs.  (A coal miner in Indonesia is not going to be able to switch to a renewal fuel job, without education, training and funding etc).  Or historical inequalities that affect politics and economies today.

This is a basic book that is a great introduction for younger people, older or sceptical people or even more advanced readers who just want summaries in one place.  But it does not provide much critical thinking or advanced complex understanding of these issues... but I don't think that is the aim of the book, if that is what you are looking for I would recommend works such as The New Age of Empire: How Racism and Colonialism Still Rule the World etc and other niche books.
