If money matters more than lives (even if it's your own or a lot of people you might care enough), then he might be right.<p>If it doesn't, then he is wrong. Never cross a river that in average is 4 feet deep, nor suppose that an increase of the global yearly average of temperature of 2 degrees excludes the possibility of 55-60 ºC on very populated cities on some particular day in a near future. That probably will kill a lot of people, and cause a lot of health troubles to a lot more. And to make it worse, it won't be an isolated event, it will keep happening and getting worse, and not affecting just people.<p>If you see what he proposes as "it will be less expensive to kill a lot of people", he might be technically right. And very wrong.
