The goal of this book is to look for linkages between two phenomena: climate change and human mobility (migration). Through reviewing contemporary literature this book examines the influence of changing climate on human behavior when it comes to decision to migrate. Are people likely to leave their homes when negatively affected by changes in their environment or will they choose to adapt and stay? Are changes of global environment likely to be so severe to provoke such strong population responses? Can climate change be the sole reason for people to migrate? Through what channels can change of climate and environment pressure residents to move? Are the conclusions of researchers sufficient for creating effective policy response? What are likely the groups being most affected and why? In the first chapter I debate determinants of migration and likely impacts of climate change in near future. In second chapter I discuss the impacts of climate change on certain areas of human life with particular attention being given to agriculture. Further I review the literature on climate events and consider them as possible push factor in the areas that are most severely hit.
