The year 2007 witnessed a major surge in interest in controlling the damage that can be done to the global economy due to the accumulation of greenhouse gases (GHGs) in the atmosphere. The Stern Review (Stern 2006) published in October 2006 and publicized in 2007 drew attention to the seriousness of the economic consequences potentially associated with a continuation of present trends in human-induced climate change. In an in-depth cost-benefit analysis (subject to the usual caveats for such analyses), Stern demonstrated that about 1 percent of Gross Domestic Product (GDP) invested in controlling GHG emissions can save an annuitized loss on a broad measure of consumption (that includes nonmarket goods and services) equivalent to 5–20 percent of GDP by mitigating the negative impacts of climate change. In February 2007, the latest assessment report of the Intergovernmental Panel on Climate Change (IPCC 2007a) articulated a growing consensus among climate scientists about the devastating effects of human-induced climate change, particularly for low-income regions and low-income people of the world. Al Gore, the former Vice-President of the United States, in his powerful documentary, An Inconvenient Truth, which won two Academy Awards, demonstrated in a graphic manner the high costs of climate change for the world, including developed countries. Since then, and also under the leadership of Al Gore, a series of Live Earth Concerts around the world have continued raising global consciousness about the dangers of climate change.
