A lot of people are warning us about climate change, and a lot of people are telling them, well it is exactly like the previous scare the world has know. You might remember those scare (hole in the ozone layer, poverity everywhere because we lack ressources for everyone, an ice age, globale warming [it's something that come back every few years apparantly], lack of food for the growing population, etc) and think, well they do have a point, none of the previous scare came through and actually cause any problem for society.
While this is true, it doesn't mean climate changes won't be a problem (I doubt it will destroy society, humanity is amazingly adaptable and resilient) in fact climate change is the first thing beside nuclear weapon that where deemed by scientist to be capable of causing the extinction of life as we know. Small parenthese at the moment, I say life as we know it because from the history of the world we find that nothing appears to be able to completly wipe life off the face of the earth and seriously if a supernovae doesn't do it, I really doubt we could.
No seriously the problem with climate change is not in the climate change themself or even if scientist agree that they happen because of humanity, no the problem (at least in my opinion) is simple. The environnement is a political agenda, for some weird reason people have claimed that one side of the political spectrum as monopoly on the environnement. A lot of people are thus reflexively doubtfull of any claim on the environnement seeing them as means toward other idea they might not agree on instead of something that concern everyone inspite of political allegence.
I think we need to push away the environnemental issues away from the political agenda, it is the only way they might be considered correctly. If we do not I fear that we will debate weither any studies or report on the issue is not biased or partisant toward a party instead of looking at the issue itself. In a way arguing about the messenger instead of the message.
