I was horrified to watch some of the recent discoveries made into "Global Dimming"- in fact this was the first time that I'd encountered it at all. It is very shocking! What I find more shocking is the fact that it hasn't been greatly publicised; not to the same extent as pollution. I found this a really motivating programme, and I am now consciously thinking of ways that I can personally decrease my culmination to the burning of Greenhouse gases. I hope there are more informative programmes like this in the future!
