The U.S. news media have a critical role to play in educating the public about climate change.

Beyond the borders of wealthy countries like the United States, in developing countries where most people in the world live, the impacts of climate change are much more deadly, from the growing desertification of Africa to the threats of rising sea levels and the submersion of small island nations.

So it is fair to ask, why not address the threat of climate change when it is still possible? Asad Rehman, of the international environmental group Friends of the Earth, who was in New York for the climate march, told me, “If we can find the trillions [of dollars] we’re finding for conflict whether there’s been the invasion in Iraq or Afghanistan or now the conflict in Syria, then we can find the kind of money that’s required for the transformation that will deliver clean, renewable energy.”

A typical Ponzi scheme involves taking money from investors, then paying them off with money taken from new investors, rather than paying them from actual earnings.

Whether you vote for me or you don't vote for me, I really want to be your greatest champion. And I will be your champion, whether you vote for me or not.

Journalism is the only profession explicitly protected by the U.S. Constitution, because journalists are supposed to be the check and balance on government. We're supposed to be holding those in power accountable. We're not supposed to be their megaphone. That's what the corporate media have become.

Go where there is silence and say something.
