Small Gases, Big Effect

Small Gases, Big Effect

This Is Climate Change


The international bestseller that gives you the facts about climate change

When students David Nelles and Christian Serrer struggled to find a book that explained the nuts and bolts of climate change in a way that was comprehensive, concise and enjoyable to read, they decided to write it themselves.

With meticulous research corroborated by over 100 scientists, Small Gases, Big Effect summarizes all the latest findings on the causes and effects of climate change. Combining clear, thoughtful writing with illuminating graphics, it is a little book that presents complex scientific evidence in a way that everyone will find easy to understand.


  • It's found its way into more than 350,000 German homes. It's been read by Merkel's agriculture minister and at least 37 MPs in the Bundestag. It's a set text in universities, engineering conglomerates and the European Central Bank. Yet the most remarkable thing about it is that, in an age of inexorably hardening political battle lines, it is really changing minds.
