save it but simply because we chose not to make the effort”(Romm, 25). Challenges and solutions identified by the book The book claims that U.S. politicians who deny the science and have failed to take genuine action on conservation and alternative energy initiatives are following a disastrous course by delaying serious changes that he says are imminently needed. Romm also criticizes the media for what he says is sloppy reporting and an unwillingness to probe behind political rhetoric, which he says are lulling Americans into accepting continuing delays on implementing emission-cutting technologies. The book argues that there is a limited window of opportunity to head off the most catastrophic effects of global warming, and it calls upon Americans to demand that our government "embrace an aggressive multi-decade, government-led effort to use existing and near-term clean energy technologies." (p. 230) Romm writes that strategies to combat climate change with current technologies can significantly slow global warming and buy more time for the world to develop new technologies and take even stronger action. The book lays out a number of proposed solutions to avoiding a climate catastrophe, including: launching massive energy efficiency programs for homes, office buildings, and heavy industry; increasing the fuel efficiency of cars and light trucks to 60 miles per gallon while also equipping them with advanced plug-in hybrid technology; building 1 million large wind turbines; and ceasing tropical deforestation and reversing the trend by planting trees. The book states, "The IPCC's Fourth Assessment Report this year (2007) will present a much stronger consensus and a much clearer and darker picture of our likely future than the Third Assessment – but it will almost certainly still underestimate the likely impacts. The Fifth Assessment, due around 2013, should include many of the omitted feedbacks, like that of the [carbon emissions caused by] defrosting tundra, and validate the scenarios described on these pages." (p. 94) Critical response The Toronto Stars January 1, 2007 review of the book says that Romm "convincingly shoots down the arguments of those who claim global warming is a hoax or some kind of natural cycle not associated with human activities." The review laments that the "'Denyers and Delayers' are winning the political battle in the United States, the world's highest emitter of greenhouse gases and a saboteur of Kyoto talks" and that the media's policy of "giving 'equal time' to Denyers gives the public the wrong
