Part of the problem is that the system is quite chaotic. A measurement change well within our instrument tolerance can give incredibly different simulation of the evolution of the climate. Heck the whole chaos theory was basically born from observations of the instability of weather models What I noticed mostly is that our forecasts are getting sensibly worse even in the short period. If I had time for a serious research, I'd look more at how some climate change happened to modify the patterns that we previously used successfully in our models because with confidence in forecast simulations dropping is gonna be very hard to make sense of any data. Especially since dire predictions from the seventies eighties and nineties all turned wrong and people is desensebilizing to the problem, even if the risk is about the unknown unknown more than the actual known
