I found this lecture to be intriguing and effective, mainly because the presenter strayed away from the worn out scare tactics that I have now been desensitized to. Instead, he took a different, rational approach, by providing a best case scenario, and showing how even this could lead to an unpleasant future for our planet, and ourselves.
By making open assumptions, and using optimistic numbers instead of pessimistic ones, he managed to take much of the bias out of his presentation, which made the impact a lot more lasting for me. It made me realize that as long as our population continues to grow (which it will), it won't matter how efficient we are with fossil fuels - the one and only permanent solution is to stop using them entirely.
By pointing out the pros and cons of every possible alternative energy and solution to climate change, he managed to highlight the gravity and magnitude of our current problem, while eliminating most options, and only leaving one plausible one left: affordable solar energy. This provided a ray of hope to this otherwise dire problem, and certainly got me to support his line of research. I now feel like I have a much greater understanding of the efficiencies and inefficiencies of all the alternative energies, as well as the concept of energy consumption, and how to solve our growing problem.
