I cannot think of a better statement – may it seem contradictory – to introduce a book dealing with climate uncertainty. Doubt, uncertainty, and indeed skepticism are inherent to science. Climate action, maybe beyond any other policy process, has been driven by climate science since the very recognition of the problem of climate change some few decades ago. Paradoxically, the inherent uncertainty of climate science was used by so-called climate skeptics to disregard climate action and the whole issue of climate change. Yet the scientifi c community, including through the IPCC, has kept providing ever- increasing data, analysis, and evidence from a multidisciplinary wealth of informa- tion, demonstrating beyond reasonable doubt that the planet is warming due to the buildup of greenhouse gases in the atmosphere. O f course, uncertainty remains present in most of our political, economic, and social decisions, including those related to the changing climate. But whereas in other policy areas action would not usually be hindered on arguments of lack of absolute certainty in presence of highly likely facts, climate action has always been questioned, including through the use of fake arguments that wrongly mix up rigor, uncertainty, and likelihood. In the meantime, global warming continues, the increased impacts of both slow-onset events and of altered regimes of extreme weather events are a reality, and global sustainability keeps a distant goal for humankind. T he publication of this book is very welcome in this context and at this stage. It deals effectively with climate uncertainty, one of the most prominent and pro- claimed barriers to developing effective adaptation action. It is true that climate policy needs to be tackled under signifi cant uncertainty from several sources, as identifi ed in Chap. 2 . But on the other hand there are several options allowing us to start, such as no-regret, win-win, and cost-effective adaptation measures, particu- larly those useful to deal with on-going climate effects, or that will be needed in any case to help solve other problems. Further, there is a rapidly increasing knowledge ix
