Comments Off on Wall Street Journal Prints Laughable Op-Ed Claiming CO2 Emissions Are Good for the Planet

Photo via Shutterstock According to a recent op-ed on the Wall Street Journal , rising CO2 levels are the best thing to happen to the planet since the Big Bang. The column was written by Harrison Schmidt, a former astronaut and adjunct professor of engineering at the University of Wisconsin-Madison, and William Happer, a professor of physics at Princeton University. In it, they claim that increased CO2 levels in the atmosphere will result in increased agricultural productivity. But mainstream science of course says this is a bunch of hooey.

In addition to co-founding Twitter, Stone helped launch Blogger, Odeo, Xanga and the Obvious Corporation (a group that helps build and invest in new technology). It seems Stone has come to the realization — perhaps with the help of recent addiction studies — that the internet sensations he’s helped to create have some people so wrapped up in them that they just can’t put them down.
