Fox News, Sept 5, 2007

We often hear the story of humans voraciously exploiting the world’s resources and living way beyond Earth’s means. On “Earth Overshoot Day”, campaigners such as the Global Footprint Network claim that, by August 2, we have already exhausted this year’s supply of natural resources and Earth is now sliding into “ecological debt” for the rest of 2017.

For this Earth Day it is especially important we focus on the world's top priorities. In September, all 193 governments will meet at the UN to set targets for the world for the next 15 years in what is explicitly labeled "Sustainable Development Goals." So, it is worth looking at what we should do first. At my think tank, the Copenhagen Consensus, we've asked 60 teams of top economists including several Nobel laureates to evaluate the economic, social and environmental costs and benefits of the targets, so we can pick the best ones. Here is what we should do in environment.

The latest alarming news about climate change is that huge swaths of densely inhabited land will be underwater by 2050, with their cities “erased.” These reports – which appeared in The New York Times and many other media outlets – are based on a good research paper by scientists at Climate Central, but they get the story wrong.

This is part of a damaging pattern. Climate change is a man-made problem that we need to tackle, but many of the news stories about its purported effects are scaring us without justification and misleading us about how to act.
