Leonardo DiCaprio took the stage at the UN to advocate for clean, renewable energy in an impassioned speech.  He said: 

Every week , we’re seeing new and undeniable Climate Events, evidence that accelerated Climate Change is here now. We know that droughts are intensifying, our oceans are warming and acidifying, with methane plumes rising up from beneath the ocean floor. We are seeing extreme weather events, increased temperatures, and the West Antarctic and Greenland ice-sheets melting at unprecedented rates, decades ahead of scientific projections. None of this is rhetoric, and none of it is hysteria. It is fact. The scientific community knows it, Industry and Governments know it, even the United States military knows it. The Chief of the U.S. Navy’s Pacific Command, Admiral Samuel Locklear, recently said that Climate Change is our single greatest security threat.
