Turns out not too damn good If we had made a prediction like this and had it turn out as it did, why we would be called charlatans...or even worse psychics 1969 to now and the predictions were off by a measly 1200 percent in one case "Rather than spiking by 3.9 C (7 degrees F), the actual temperature increase between 1969 and the year 2000 was a practically imperceptible 0.3 C. Which means the experts were off by 1200 percent. And 2950 percent in the other "Most embarrassing of all, rather than rising 305 cm (10 feet), sea level increased by a paltry 10 cm (3.9 inches). Which means the experts overestimated that particular danger by 2950 percent." No Frakking Consensus: 1969 Climate Predictions Miss by a Mile Yep real good predictions there people! Keep it up!
