I get it - Americans want to have their guns. And I can understand a lot of the arguments in favor of gun ownership. You can build a case that someone has a right to a gun to protect him or herself and their family. You can build a case that someone has a right to a gun to go hunting. You can build a case that someone has a right to a gun for competitive shooting. You can build a case that someone has a right to a gun if they're in the business of protecting the nation - like the national guard or the reserves. In fact - that last one on the list was the real original reason the Founding Fathers wrote the Second Amendment...it was to protect the nation. Rewind back to the early days of America - even after the British were beaten back in the Revolutionary War there was still tremendous fear that American was vulnrable to attack. It could be the Spanish coming up from Florida. Or the French - or the British again - coming down through Canada. And most of our Founding Fathers also had an enormous fear of standing armies during times of peace - after all, thousands of years of history showed them that great nations that kept a standing army during times of peace were often taken down by that very army in a military coup. Jefferson wrote exhaustively on this - even threatening to blow up the Constitution since it didn't include protections from standing armies. As Jefferson wrote to James Madison in 1787: "I do not like [in the new Federal Constitution] the omission of a Bill ...

A Koch brother-funded climate change skeptic has suddenly reversed course - and now proclaims that humans are "entirely the cause" of global climate change. Three years ago - this guy - physicist Richard Muller - was given $150000 from the Koch brothers to co-found the Berkeley Earth Surface Temperature Project to debunk climate change arguments. But on Sunday, after three years of intense research, Muller is biting the hand that feeds him by promoting genuine science and ringing the alarm bell that climate change is happening and humans are to blame. As Muller wrote on Sunday in the New York Times: "My total turnaround, in such a short time, is the result of careful and objective analysis... it appears likely that essentially all of this increase [in temperatures] results from the human emission of greenhouse gases." From unprecedented ice melting in Greenland - to unprecedented heat waves and droughts in America - to sudden die-offs of reefs and phytoplankton in the oceans - the world is changing rapidly. And even Koch-funded scientists can't deny it anymore. Unfortunately - it may now be too late. Centuries of hurling toxic greenhouse gasses into the atmosphere may have already pushed the world passed the climate change threshold. Meaning in the coming years, decades, centuries - our planet could be radically different than we are prepared to handle. For more on this - Bill McKibbon joins me - he's an environmental activist and founder of 350.org - as well as the ...
