Bjorn Lomborg argues that many of the elaborate and staggeringly
expensive actions now being considered to meet the challenges of global
warming ultimately will have little impact on the world's temperature.
He suggests that rather than focusing on ineffective solutions that will
cost us trillions of dollars over the coming decades, we should be
looking for smarter, more cost-effective approaches (such as massively
increasing our commitment to green energy R&D) that will allow us to
deal not only with climate change but also with other pressing global
concerns, such as malaria and HIV/AIDS. And he considers why and how
this debate has fostered an atmosphere in which dissenters are
immediately demonized.
