Which we tend to hear about warming or cooling?

Bjørn Lomborg writes in the ET “implementing the Kyoto Protocol at a cost of $180 billion annually would keep two million people from going hungry only by the end of the century. Yet by spending just $10 billion annually, the United Nations estimates that we could help 229 million hungry people today. Every time spending on climate policies saves one person from hunger in a hundred years, the same amount could have saved 5,000 people now. Arguably, this should be among Obama’s top priorities”.
