I am an avid reader of the Economist and appreciate the in-depth analysis and global perspective. The magazine just published a video on what the world would look like with 3 degrees of warming. Sorry, but yes, we are on track to hit that number by the end of the century. Those of us in western developed nations might complain about the heat, but rarely do we consider climate change the existential threat that it poses to the majority of the inhabitants of the planet. This video helped to open my eyes to the plight of many and the risks to our civilization. When you get a moment, this 16 minute video is worth the time.
