>>1376358>last few hundred yearsNot enough data to produce a coherent understanding of the most complex system known to us. We can’t even predict with certainty tomorrow’s weather, let alone weather patterns on the scale of hundreds of years. The variability is too great, even accounting for known cyclical patterns like La Nina/ El Niño, axial tilt, solar irradiance, etc. Climate patterns are far more complex than a very loosely correlative relationship between temperature and anthropogenic green house gases.
