Unless we differentiate between possibilities and probabilities we will keep spinning our wheels and allow powers-that-be to lie and obfuscate. A technical possibility of 1.5C using CCS, net zero accounting tricks and solar panels built with pixie dust while ignoring the exponentially increasing energy needs of an economy and a financial system addicted to constant growth is a lie. It may technically not be a Zero probability event but even a basic understanding of statistics would make one realize that betting the whole planet on an approach that is 3 standard deviations away from the mean is foolish.
