Abstract

Humans are slowly awakening to the idea that they are dependent on the environment for their survival and this is derived from the fact that, until recently, human evolution was heavily reliant on the environment for water, food, and good health and will continue to remain so, during the next few decades. These are needed now more than ever, despite modern technology and seeming endurance in the face of often damaged settings. The conditions for human sustainability (water quality and quantity, food security, and health) are now potentially threatened by various human-induced causes, out of which, climate change is one of the more durable. This paper will focus on the likely evolution of climate in the twenty-first century, as well as important climatic implications that may shape the future of human society, such as resource wars, environmental conflicts, and migrations.
