Overview of Book

This book is organized to cover the major topics that, in our opinion, are needed to address this interdisciplinary subject. Part 1 of the book includes essential background information on food security and trends in the climate system. Chapter 2 presents an overview of food security and the potential ways that it can be influenced by climate changes. Chapter 3 presents an overview of climate models and how they are used to assess uncertainties in the future of climate.

Part 2 delves into the links between climate and crop yields, with a focus on how and how well scientists attempt to quantify these links with models and experiments. Chapter 4 describes the process-based ecophysiological crop models that underlie many assessments of yield impacts, while Chapters 5 and 6 discuss statistical approaches that model yields based on relationships gleaned from historical yield variations across time and space. Chapter 7 focuses on crop responses to elevated CO2, a critical factor for projecting future yield impacts.

Part 3 provides an in-depth look at different adaptation options that may play a key role in minimizing impacts over the next few decades. Chapter 8 reviews market-mediated adaptations through trade, as well as on-farm agronomic adaptations such as shifts in planting dates or crop varieties. Chapter 9 discusses the key role that crop development can play in generating new seeds that can better thrive in a new climate.

Finally, Part 4 takes a snapshot of current research, with Chapter 10 summarizing results from recent regional and global assessments and Chapter 11 focusing on major lessons from past work and suggestions for future research.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
