Lomborg on MSNBC's Melissa Harris-Perry's show

How do we best spend our scarce resources to do good in the world?

In his talk to Reason Foundation, Lomborg takes you though how to prioritize the solutions to some of the world's greatest problems.

At 8:30 p.m. on Saturday, people and public places across the globe will switch off their lights for one hour to raise awareness about the impact of energy use on climate change. Unfortunately, this Earth Hour event is nothing but an ineffective feel-good event. It does little for the climate in terms of reducing CO emissions and distracts us from the real problems and solutions — especially giving light to those in the darkness.

The Doha meeting continued 20 years of failed climate negotiations, since the original Earth Summit in Rio in 1992. There, countries pledged to cut greenhouse-gas emissions to 1990 levels by the year 2000; the OECD countries fell short by almost 9%. The Kyoto Protocol from 1998 has almost entirely failed. And the effort intended to save the world in Copenhagen in 2009 collapsed spectacularly.
