Bjorn Lomborg's analyses are well known for being highly motivated to push contrarian agendas, and shouldn't be taken as evidence of any sort of honest analysis. His thoughts are only useful to drive out of the box thinking, and should not be taken earnestly in any way.
This would be like asking "but how does all this new molecular biology work showing how smoking causes mutations that drive lung cancer square with Ronald Fisher's analysis showing that smoking is just correlated with lung cancer?" It just doesn't matter, because we need to realize when people are using statistics and analysis to push particular agendas, rather than using it to answer questions about the world.
