I strongly recommend watching this informational and educational video program on the National Geographic Channel on satellite or cable television. It is an excellent production with plenty of worthwhile critical material that helps one understand where the planet is at and where certain thresholds are in the coming years and decades. It is quite apparent some localized spikes to a level of three degrees warming have already occured in places in the last decade, but just for a season to a year. A more permanent longer trend is coming soon most everywhere.*****
