I suppose that most of us are aware of the climate change impacts and the long-term irreversible problems that will be created. I also suppose that many people, although they do not doubt at all for the core climate change arguments, are thinking that sometimes the impacts and the urgency are somehow exaggerated. Of course, there are climate change deniers (some of them as serious as Donald Trump who recently twitted “This very expensive GLOBAL WARMING bullshit has got to stop. Our planet is freezing, record low temps, and our GW scientists are stuck in ice”). And, finally, there is a also a huge grey area of people that are thinking that “the scientific facts are too complex to be understood” or that “this is one more sign of the environmental catastrophe that is often predicted” or simply that “ok, but human are too genius and they will find their way to manage the problem”.
