Yes or No to a National Carbon Tax

This Friday, world leaders and their entourages will disembark from carbon-spewing jets in New York to sign the world’s costliest climate change treaty. Lit by the flashbulbs of the world’s press and warmed by their sense of accomplishment, these politicians will pat each other on the back and declare a job well done.

The reality is that the so-called “Paris Treaty” is a hugely expensive way of doing very little.

Global leaders recently swept into New York for the United Nations General Assembly, trailed by thousands of media, activists and protestors. During the high-level get-together, two very different meetings held at the exactly same time revealed much about their priorities—and their flawed approach to the planet’s biggest problems.

The United Nations Climate Change Conference in Paris later this month is being billed as an opportunity to save the planet. It is no such thing. As I show in a new peer-reviewed paper, even if successful, the agreement reached in Paris would cut temperatures in 2100 by just 0.05° Celsius. The rise in sea level would be reduced by only 1.3 centimeters.
