There was no Earth Day speech. No urgent call to action. No outlining of the threats we face or the way in which we were going to work together to meet them. There wasn't even an Earth Day tweet -- just silence. It was a very stark reminder of his priorities. U.S. President Barack Obama's speech noted that we are already experiencing the impacts of climate change. The fact that 2014 was the hottest year ever recorded, that droughts, storms, and wildfires are increasing all over the planet in both frequency and intensity, and how climate change is already adversely affecting the air our children breathe.
