Abstract

Climate change is one of the most crucial problems facing the global community at the present time. Climate change will affect not only the well-being of future generations but the prospects of those who are currently alive. At the time of writing this introduction, news outlets across the world were reporting that global temperatures for February of this year showed an unprecedented upward spike.' According to NASA data, it was 1.35°C warmer than the average February during the baseline period of 1950-1981. Even more disturbingly, this is the biggest temperature anomaly since records began in 1880. At the same time, Arctic sea-ice cover recorded its lowest ever February value. Many commentators in those reports spoke understandably of a climate emergency at our very doorstep. These alarming statistics illustrate the rapid changes occurring across the globe and demonstrate the urgency of the climate challenges that confront us. In responding to climate change and in formulating climate policy, economic analysis and economic solutions will undoubtedly be two of the key tools employed by policymakers. They will be central to the solutions that governments and other relevant institutional agencies develop to the challenge of climate change. Indeed climate economics has been at the heart of much of the recent policy debate.
