PrintModule 9.1: Understanding Global Climate Change and Food Systems
We hear a lot about global climate change and global warming in the news, especially about the controversy surrounding proposed strategies to reduce carbon emissions, but how well do you understand the science behind why our climate is changing and our planet is warming? In this unit, we'll review the basic science that underpins our understanding of global warming. Agriculture is one of the human activities that contributes carbon dioxide to the atmosphere, so we'll consider those contributions and how they can be reduced. Finally, we'll start to look to the future. What are some of the projections for future temperatures? We need to know what the future projections are so that we can plan to make our food systems more resilient to expected changes.
