An initial disclaimer is in order here, I think. Being that the "Discovery" account is most likely anything but an official, sanctioned, online representative of the National Geographic Channel, and I therefore have no idea how long it will be before a DMCA complaint removes this video or the YouTube channel itself, I will provide a more authorized link to the program here, which, with a registered account, may let you watch it in its entirety.
Disclaimer now fully disclaimed, onto my review of the video...
Quite honestly, I was prepared to cringe the whole time I watched it, but I should have known Nat Geo would do a better, less sensational job with the topic than, say, the Discovery or History Channel. The cameo by Ken Caldiera, someone who truly appreciates and understands the science of climate change, was a welcomed surprise, and the cons of each technological fix were at least mentioned in brief, in contrast to what I anticipated going in. Still, the cons needed more elaboration, because their costs and dangers are greater and more extensive than what was depicted, but in an hour-long show with ads how much detail can one expect? If you need an overview of the mad-scientist-style remedies for global warming being cooked up out there, it's worth a watch.
