I enjoyed this [relevant] commentary from the study:
One of the major candidates in the current Presidential primary in the United States has declared (http://www.cbsnews.com/8301-503544_162-20093535-503544.html) that human-made global warming is a hoax, and he has issued an official Proclamation: ” I, Rick Perry, Governor of Texas, under the authority vested in me by the Constitution and Statutes of the State of Texas, do hereby proclaim the three-day period from Friday, April 22, 2011, to Sunday, April 24, 2011, as Days of Prayer for Rain in the State of Texas. I urge Texans of all faiths and traditions to offer prayers on those days for the healing of our land, the rebuilding of our communities and the restoration of our normal way of life.”
Science cannot disprove the possibility of divine intervention. However, there is a relevant saying that “Heaven helps those who help themselves.”
Science does show that business-as-usual fossil fuel emissions will cause atmospheric CO2 to continue to increase rapidly. The increasing greenhouse gases will cause the rapid global warming of the past three decades to continue, and this warming will cause the climate dice to become more and more loaded with greater and greater extreme events. The probability that this conclusion is wrong is about as close to zero as one can get.
Fortunately, it is not necessary to continue business-as-usual. In a paper that we are working on with a number of distinguished colleagues we argue that an appropriately rising price on carbon emissions could move the world to a clean energy future fast enough to limit further global warming to several tenths of a degree Celsius. Such a scenario is needed if we are to preserve life as we know it.
