Today, the world is facing great challenges to produce adequate food, fiber, feed, industrial products, and ecosystem services for the Earth’s 6.4 billion people. Climate changes and agriculture are interrelated processes, both of which take place on a global scale. Climate change is affecting the food quality because of the increasing temperature and decreasing crop growth period. With nearly 80 million added every year, we must develop ecosystem goods and services to meet the needs of 8 billion by the year 2025 and over 10 billion by 2050. Global warming is a major and controversial issue all over the world, it affects many aspects of life; agriculture, plant and animal biodiversity, environment and socio-economic well being. Environmental changes have important implications, some positive and others negative, for future crop yield and production. Global warming will bring about heat stresses on plants that will even affect the types of crop grown; hence plant breeding programmers need to make necessary changes to adopt environment-specific approaches to crop improvement for fulfilling additional demands on crop production.
