This chapter indicates the advanced issues of global warming, the significant aspects of climate change, climate change and crop production, climate change and risk issues, and the public perceptions of climate change. Global warming and climate change are the important environmental concerns that have a major impact on various environmental perspectives. The effects and impacts of global warming are climate change, sea level change, water balance, and human health. The problems of global warming and climate change can be controlled by minimizing the emission of greenhouse gases into the environment through conducting laws, reducing thermal power generating stations, planting trees, and sharing vehicles. Global warming and climate change must be recognized by local governments and environment-related international organizations in order to find the effective approaches to reducing their impacts in environmental settings.
