I read this news and I felt unconfortable. The original paper mentions some ways that should be quite effective to reduce black carbon production in the 3rd world. It says it would cause a double benefit: current generation people health improvement and reduction of climate change for future generations without the sacrifices derived from CO2 reduction policies. It refers to a science paper I have not read, so my views can be too superficial but I don’t like the idea behind, because I consider it dangerous.
It would be wonderful to solve the climate change problem with a technical advance or uniquely a win-win solution like this. It was done with the ozone layer problem by eliminating the CFCs, but I am afraid this time it is not so easy. Saying that any solution that involves economic sacrifice will not be implemented drives us to a dark future. I find it much more hopeful to say that short term economic sacrifice will lead us to a long term gain, as proposed by Tony Blair. In the other hand, selling the fantasy of an easy solution without sacrifice maybe dangerous and even counteracting, because we can loose a valuable time and we are running out of time.
By contrast, I like the approach of Joe Romm to combine this short term strategy with a long term CO2 reduction one. In some cases we do not have to choose, just take the best from each one.
