I never understood the science behind global warming. Once I learned it, I no longer understood how one could deny the science. Our Earth is amazing – for better or for worse.
This video (2 minutes 50 seconds) does a great job explaining what global warming is – in layman terms – for all of us who are not environmental scientists! You will also learn why it matters to us as human beings. I don’t think National Geographic would let me embed it so you have to click through to it either on the screen shot below or link underneath.
