CHAPTER ONE

GENERAL INTRODUCTION

Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including; for example, extreme events.[1] The earth’s climate is naturally variable on all time scales. However, its long-term state and average temperature are regulated by the balance between incoming and outgoing energy, which determines the Earth’s energy balance. Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. As these factors are external to the climate system, they are referred to as ‘climate forcers’, invoking the idea that they force or push the climate towards a new long-term state – either warmer or cooler depending on the cause of change.[2] Different factors operate on different time scales, and not all of those factors that have been responsible for changes in earth’s climate in the distant past are relevant to contemporary climate change. Factors that cause climate change can be divided into two categories ­- those related to natural processes and those related to human activity. In addition to natural causes of climate change, changes internal to the climate system, such as variations in ocean currents or atmospheric circulation, can also influence the climate for short periods of time. This natural internal climate variability is superimposed on the long-term forced climate change.[3]

1.1. Background of the Study

It is no longer news that that global climate system is warming uncontrollably due to anthropogenic activities of human beings. Unfortunately, human beings who are the major causative agents of climate are also the victims of its devastating effects. It is against this backdrop we seek to evaluate the causes and effects of this adverse change of our climate system and proffers some processes and procedures by which mankind that are also the causative agents can mitigate the effects of climate change and/or adapt to it. The path of environmental law has come to a cliff called climate change, and there is no turning around as climate change policy dialogue emerged in the 1990s, however, the perceived urgency of attention to mitigation strategies designed to regulate sources of greenhouse gas emissions quickly snuffed out meaningful progress on the formulation of adaptation strategies designed to respond to the effects of climate change on humans and the environment. Only recently has this “adaptation deficit” become a concern now actively included in climate change policy debate. Previously, treating talk of adaptation as taboo, the climate change policy world has begrudgingly accepted it into the fold as the reality of failed efforts to achieve global mitigation policy has combined with the scientific evidence that committed warming will continue the trend of climate change well into the future regardless of mitigation policy success. But we do not expect adaptation policy to play out for environmental law the way mitigation policy has and is likely to continue.
