It's funny how you attack Arctic News Blog as "tin-foil hat" stuff, yet you cannot refute a single scientific fact stated there. That four year timeline is a conjecture, and like it or not a real possibility. Further, it is absolutely moronic to insist that telling people there is a threat 100 years in the future is going to motivate them to change anything. That is a joke.
Then you go on to attack someone who pointed out what an ineffectual failure the Paris agreement was. This is widely known, was widely reported here at CD at the time of the signing, and isn't even remotely controversial. Yet you attack that FACT by smearing the person who brings it up as some sort of closet Trump supporter.
Finally you attempt to tar anyone who points out these sorts of truths —you know, the kind of truths that make neoliberal Hillary and Obama boosters squirm— as some sort of bad leftists.
Basically, you appear to be a con artist and a liar, using ad hominem atttacks to police discourse around here in an attempt to channel it into a neoliberal framework, presumably in support of pro-capitalist and pro-globalist politicians and policies. You sound in fact like a typical neoliberal Democrat, misrepresenting yourself as a "leftist."
In short: you come across as a transparent snake, and at a politically sophisticated site like CD you won't get away with that without people calling you exactly that.
