The issue OP is making is that climate scientists have forecasted "tipping points"[0] for years on end now, and none of them have come true. It ruins the credibility of these "point of no return" articles.
Not sure what sort of "coming true" you guys are expecting. We're looking at a pretty unusual level of drought, fires, and flooding disasters all over the world, new temperature records almost every year, and faster temperature increases and ice loss than the IPCC had projected.
Back in 2007 the book Six Degrees was published, with one chapter per degree of warming, summing up the science of what results we would see. We're at one degree and everything in that chapter is happening now.
