Yannick Cornet Posted over 3 years ago James Hansen: Why I must speak out about climate change Some very interesting insights here, but some really surprising discussions too - and video for that matter. I mean, this is Rio+20 and some people in some so-called 'developed countries' are still arguing about this? Wou-haa. Sounds like a waste of time to me (like me even commenting here). Can we please get into action now? Yes that means removing all oil subsidies and internalizing fossil fuel so-called 'external costs' into our economies. Arhuing more is just giving credibility to the late adopters.
