Internal changes in hydroclimate influencing global temperature on centennial scale

In a new study in Nature Communications by Michael L. Griffiths et al found that ENSO and related hydroclimate phenomena in the western Pacific produce significant changes in global temperature on a centennial scale. The study presents a 2,000-year multiproxy reconstruction of the western Pacific and concludes that there is a

likelihood that century-scale variations in tropical Pacific climate modes can significantly modulate radiatively forced shifts in global temperature.

So maybe it’s not all CO2 after all.
