Being an IT Risk Manager, I understand how to perform risk assessments, whether they be on IT stuff or normal everyday decisions that need to be made, which is why I believe that action on lowing humans carbon footprint is so essential. In his video series, Greg has made a complex argument quite simple, and judging by this amount of hits on his YouTube series, he has made some impact. But what gets me is this. His initial video discussed the pro's and con's of action and inaction based upon whether anthropogenic climate change is actually occurring or not back in 2007, and we still have not done a hell of a lot about it. I could rant on all night, however the results of his risk assessment is quite compelling, and I totally agree with his assumptions.
Now if you what to know what this guy is on about, well let me show you. It is a bit nerdy, but please stick it out for the entire 10 minutes as I believe you will find this quite interesting.
