> Our new study shows that protracted droughts frequently occurred during the past millennia, but we do not have a good understanding of why the monsoon failed in those years. Similar studies using Himalayan ice cores, tree rings and other caves have also detected protracted droughts but face the same challenge. So we’ll just blindly attribute this to man-made climate change and move on?
