“When the solution to a given problem doesn’t lay right before our eyes, it is easy to assume that no solution exists. But history has shown again and again that such assumptions are wrong. This is not to say the world is perfect. Nor that all progress is always good. Even widespread societal gains inevitably produce losses for some people. That’s why the economist Joseph Schumpeter referred to capitalism as “creative destruction.” But humankind has a great capacity for finding technological solutions to seemingly intractable problems, and this will likely be the case for global warming. It isn’t that the problem isn’t potentially large. It’s just that human ingenuity—when given proper incentives—is bound to be larger. Even more encouraging, technological fixes are often far simpler, and therefore cheaper, than the doomsayers could have imagined. Indeed, in the final chapter of this book we’ll meet a band of renegade engineers who have developed not one but three global-warming fixes, any of which could be bought for less than the annual sales tally of all the Thoroughbred horses at Keeneland auction house in Kentucky.”

“When Al Gore urges the citizenry to sacrifice their plastic shopping bags, their air-conditioning, their extraneous travel, the agnostics grumble that human activity accounts for just 2 percent of global carbon-dioxide emissions, with the remainder generated by natural processes like plant decay.”

“In the United States especially, politics and economics don’t mix well. Politicians have all sorts of reasons to pass all sorts of laws that, as well-meaning as they may be, fail to account for the way real people respond to real-world incentives.”

“In a complex world where people can be atypical in an infinite number of ways, there is great value in discovering the baseline. And knowing what happens on average is a good place to start. By so doing, we insulate ourselves from the tendency to build our thinking - our daily decisions, our laws, our governance - on exceptions and anomalies rather than on reality.”

“Why? What is so wonderful about mass murder that nobody in the history of the world has ever fond any smarter solution to problems than killing everybody who doesn’t agree? Is that the limit of human intelligence?”

“An incentive is a bullet, a key: an often tiny object with astonishing power to change a situation”

“Every problem has a solution. Sometimes it just takes a long time to find the solution -- even if it's right in front of your nose.”
