The impact of weather and climate extremes can be severe and wide-ranging although, in some cases, the impact can also be beneficial. Weather and climate extremes affect all sectors of the economy and the environment, including human health and well-being. This book assesses whether climate extremes are changing in terms of a variety of characteristics, including intensity, duration, frequency, or spatial extent, and how they are likely to evolve in the future. In addition, a summary of the highlights of scientific research and assessments related to human-induced climate change is presented.
